In early December 2014, I wrote a six-part series of articles titled “To Bathe, or Not to Bathe“. Then, I was not aware of the existence of R. David Whitlock, a chemical engineer and a graduate of Massachusetts Institute of Technology (MIT) who had not showered in the past 12 years.
Whitlock claims that he has not taken a shower in over 12 years because soap and bath gels affect and deplete the natural balance of the skin microbiome.
Justin Sonnenburg, a microbiologist at Stanford, regards the human body as “an elaborate vessel optimized for the growth and spread of our microbial inhabitants.”
According to Published research for every one human gene, there are 100 associated genes within our microbiome. And so, more than 100 trillion microorganisms live in and on our body. They live in our mouths, tongues, guts, mucosal surfaces and on the surface of our skin.
These microbes perform various beneficial functions relevant to supporting life. They help to digest food, prevent disease-causing pathogens from invading the body, and synthesize essential nutrients and vitamins.
Changes in the microbiome can trigger changes in human cellular activities, resulting in disease or contribute to its progression.
Ammonia-oxidizing bacteria (AOB)
In the late 1990s, when David Whitlock went on a date with a young woman, she asked him why her horse liked to roll in the dirt.
Unable to answer her, Whitlock read books on biology. He gathered soil samples and grew bacteria in his basement. After reading hundreds of papers, he concluded that it must be important for the horses to roll in the dirt.
He learned that sweat of the horse is abrasive to its skin and causes equine acne that starts as a small, oily black plugs in the skin and may develop into red, itchy inflamed bumps.
He found ammonia-oxidizing bacteria (AOB) in the soil. He realized that ammonia-oxidizing bacteria (AOB) in the soil must be helping the horse to clean itself by converting urea and ammonia found in sweat into nitrite and nitric oxide.
Nitrite fights most bad bacteria while nitric oxide has anti-inflammatory properties.
In the following video, Dr. Larry Weiss, MD, a Key Member and Chief Medical Officer of AOBiome LLC talks about AOB.
From his study of the behavior of the horses, Whitlock concluded that useful bacteria once colonized on human skins too, and with the advent of knowledge in Chemistry and modern hygiene, humans eradicated them by sterilizing their bodies with soaps, lotions, and antiseptics, leaving our skin more susceptible to challenge.
Whitlock believed that by restoring the appropriate AOB levels, a range of human health conditions could be impacted.
In 2000, to test his hypothesis, Whitlock began adding AOB to water and dousing himself daily. He avoided using soaps because they kill the microbes. For the past 12 years, Whitlock did not shower. He found that the bacteria kept him clean and odor-free. His skin looks fresh, and he smells nice.
Though Dave Whitlock does not shower, he takes an occasional sponge bath to clean off the accumulated grime on his skin.
On August 10, 2001, Dave Whitlock presented his application papers for obtaining a patent for compositions, including ammonia oxidizing bacteria to increase production of nitric oxide and nitric oxide precursors and methods of using same. He obtained the patent US7820420 for same on October 26, 2010.
A method of enhancing health through the generation in close proximity of a surface of a subject, nitric oxide and nitric oxide precursors using bacteria adapted to oxidize ammonia and urea derived from perspiration is described. Local and systemic effects are described including a reduction in vascular disease, enhancement of sexual function, improved skin health, and reduced transmission of sexually transmitted diseases.
NitroCell BioSciences LLC
In 2012, Dave Whitlock co-founded NitroCell BioSciences LLC as a pharmaceutical company based in Cambridge, Massachusetts. The company focused on getting U.S. Food and Drug Administration approval for bacteria-based prescription therapies for acne, eczema, rosacea, wound healing, and more.
In March 2013, NitroCell BioSciences LLC changed its name to AOBiome, LLC.
Now, AOBiome, LLC develops skin products based on ammonia-oxidizing bacteria (AOB). The company’s products are used to restore the natural balance of skin microbes that have been lost due to modern living practices, including the use of soaps and shampoos. It also develops AO+ Refreshing Cosmetic Mist, a cosmetic product to improve the look and feel of skin.
According to Jasmina Aganovic, an MIT graduate and AOBiome’s general manager for consumer products, as humans, we need to reconnect with our environment. “We’ve confused clean with sterile. … We’ve taken the dirt out of our lives. We don’t spend as much time outdoors as we used to — even as little children.”
So, AOBiome, LLC has created and launched “Mother Dirt” to add a little dirt back into our lives. AOBiome is the first cosmetics company to market a product that contains live bacteria. The company claims their products do not cause illness, even if ingested.
The Mother Dirt products set themselves apart from all other scientific skincare items that have flooded the market in recent times.
The Mother Dirt AO+ mist specifically contains live ammonia-oxidizing bacteria (AOB) that’s sprayed on the skin twice a day. It has no odor and feels like water. There’s aMother Dirt shampoo and cleanser that doesn’t contain bacteria, but Jasmina Aganovic says it won’t interfere with it either.
Though Dave Whitlock still doesn’t shower, he uses Mother Dirt every day and hopes the rest of the world will join him. He said: “I would like a billion people a day to use this.”
Aobiome officials believe in the health benefits of these live bacteria. They are not making any scientific claims right now, but they will soon begin clinical trials on inflammatory skin conditions like acne.
On October 9, 1825, the ship Restauration came into the New York Harbor with immigrants from Stavanger, Norway. It was the first organized official immigration of Norwegians to America.
Stories of Leif Erikson’s journey to Helluland (Baffin Island), Markland (Labrador coast) and Vinland (areas around the Gulf of St. Lawrence) in North America later helped the Nordic immigrants to the United States to identify themselves with pride with the great explorer of the new found land.
New England region of the Northeastern United States consists of the six states of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. In the nineteenth century, the theory that Leif Erikson and his men visited New England gained popularity. Many believed that Cape Cod in Massachusetts could have been the Vinland of the Viking sagas.
In 1887, the first statue of Leif Erikson created by the American sculptor and poet Anne Whitney was erected on Commonwealth Avenue in Boston, Massachusetts. It was followed by the erection of another statue of Leif Erikson in Milwaukee by Anne Whitney.

The Norumbega Tower, Weston, Massachusetts.
In 1889, Eben Norton Horsford, a Harvard Chemistry professor, erected the Norumbega Tower in Weston, Massachusetts at the confluence of Stony Brook and the Charles River. He built it to mark the supposed location of Fort Norumbega, a Norse fort and city. The tower is approximately 38 feet tall, composed of mortared field stones with a spiral stone staircase.
Horsford believed that the Algonquin word ‘Norumbega’, means the general region that is now coastal New England. Convinced that the word “Norumbega” was derived from “Norvega” meaning Norway, he believed Norumbega was Vinland.
In 1901, the city of Chicago erected the statue of Leif Erikson that was commissioned for the 1893 World’s Columbian Exposition.
In 1925, during the centenary celebration of the first official immigration of Norwegians in America, President Calvin Coolidge told a crowd of 100,000 people at the Minnesota State Fair that Leif Erikson had indeed been the first European to discover America.to America,
Replica of Leif Erikson’s Viking ship in Duluth
Visitors to the Leif Erikson Park and Rose Garden in Duluth, a seaport city in the State of Minnesota, USA, can view the replica of a Viking ship built in 1926 in Norway by local boat builder Christian Overlier for Captain Gerhard Folgero. It is not an exact replica of a Viking craft, but a representation of the same class and style of boat likely used by Leif Erikson himself.
The ship on display is a 42-foot wooden fembøring vessel patterned after the traditional Norwegian working craft constructed of fir or pine. Medieval Norse adventurers, explorers, traders, and fisherfolk used this type of crafts. Architects consider the dragon’s head and tailpiece fitted on the ship to be masterpieces.
Captain Folgero and his crew sailed the fembøring vessel from Bergen, Norway, to the coast of Labrador and beyond, following much of Leif Erikson’s original sea route. From Labrador, they reached Boston, covering in all 6,700 miles in 50 days. During their voyage, they faced hurricane-like winds, icebergs, and fog.
From Boston, they sailed on to Duluth to take part in a national convention of Norwegian emigrants invited by the Norwegian-American immigrant and businessman H.H. Borgen.
The crew landed in Duluth on June 23, 1927.
Bert Enger, a Norwegian immigrant and West End furniture dealer along with the wife of his late business partner, Emil Olson, purchased the Norwegian boat and presented it to the city of Duluth. The ship placed on display in Duluth’s Lake Park was later named Leif Erikson Park. The boat was once considered Duluth’s second-largest tourist attraction after the Aerial Lift Bridge.
In 1929, the Wisconsin Legislature passed a bill to make October 9 “Leif Erikson Day”.
A few have speculated that Norsemen may have penetrated as far as Minnesota, either down from Hudson Bay or going west through the Great Lakes. Some researchers suggest that the Mandan Indians showed evidence of being culturally influenced by pre-Columbian explorers from Europe. A Runestone with carvings of a Scandanavian nature was discovered near Kensington, Minnesota, dating to approximately 1030.
On October 9, 1949, a statue of Leif was erected near the State Capitol in St. Paul, Minnesota.
In 1964, the United States Congress authorized and requested the president to proclaim October 9, of each year as “Leif Erikson Day”.
On October 9, 1968, Leif Erikson Day, the United States issued a commemorative stamp to honor Leif Erikson, the first Viking colonizer of North America.
The “Saga of the Greenlanders” (“Grænlendinga saga” in modern Icelandic) tells that in the summer of 986, Bjarni Herjólfsson, a Norse explorer sailed to Iceland as usual, to visit his parents. Since his father had migrated to Greenland with Erik the Red, Bjarni with his crew set off to find him.
In the 10th century, they had no map or devices such as compasses to guide them. Neither Bjarni nor any of his crew members had been to Greenland before. A storm blew them off course. Bjarni and his crew saw a piece of land covered with trees and mountains. The land looked hospitable. They were not sure whether it was Greenland. Although his crew begged him to, Bjarni refused to stop and explore the new lands. He was much eager to reach Greenland to see his parents.
So, Bjarni Herjólfsson was the first European to have made landfall there and see North America beyond Greenland.
After regaining his course, and arriving in Greenland, Bjarni reported seeing the low-lying hills covered with forests some distance farther to the west. But at the time no one seems to have shown interest. Later, word spread of the lands to the west, which Bjarni Herjólfsson had seen.
As they lacked timber, Greenlanders took a special interest in what Bjarni described. They became allured by the wooded coastline Bjarni had seen. It created a great intrigue throughout the Nordic Empire. Though Bjarni was celebrated by the Greenlanders, King Eric chided him for not exploring that land mass.
In 999, Leif Erikson, the son of Greenland leader Erik Thorvaldsson (Old Norse: Eiríkr Þorvaldsson), also known as Erik the Red (Old Norse: Eiríkr hinn rauði), travelled from Greenland to Norway.
Blown off course to the Hebrides and staying there for much of the summer with his crew, Leif arrived in Norway. He became a hirdman of King Olaf Tryggvason. He converted to Christianity from Norse paganism and took on the mission of introducing the new religion to Greenland.
Leif Erikson, having heard the story of Bjarni Herjólfsson, approached Bjarni and purchased the ship he had used for his voyage.
The Saga of Erik the Red says Leif Erikson hired a crew of 35 men. He planned to take his father, Erik the Red along with him in his expedition, however, Erik fell off his horse on the way to the ship, and this was taken as a bad omen and stayed at home. Leif with his crew set out towards the land Bjarni had described. He retraced Bjarni’s route in reverse.
They first went up the West Coast of Greenland and then crossed the Davis Strait and landed first in a rocky and desolate place which he named Helluland (“the land of the flat stones”), possibly Baffin Island.
Then, they went down south and found a forest area which amazed them because there were no trees in Greenland. They named the region Markland (“Wood Land”), possibly Labrador coast.
After two more days at sea, they landed in a luscious place. Relative to Greenland, the weather was mild. Salmon was aplenty in the streams. They named the region Vinland (“land of pastures”).
During one of these explorations, they found the land was full of vines and grapes. Leif and his crew built a small settlement, which later visitors from Greenland called Leifsbúðir (Leif’s Booths).
The earliest record of the name “Winland” is in chapter 39 of Adam of Bremen’s “Descriptio insularum Aquilonis” (“Description of the Northern Islands”) written c. 1075. Adam implies that the name contains Old Norse “vín” (Latin “vinum” meaning “wine”):
“Praeterea unam adhuc insulam recitavit a multis in eo repertam occeano, quae dicitur Winland, eo quod ibi vites sponte nascantur, vinum optimum ferentes.“
“In addition, the island discovered by many in one of the seas, which is called Winland, from the fact that the spontaneous growth of grapevines, produced the best wine.”
This etymology retained in the 13th-century Saga of the Greenlanders, provides a circumstantial account of the discovery of Vinland, and named from the vínber, i.e. “wine berry,” a term for grapes or currants (black or red), found there.
Archaeological evidences suggest that Vinland may have been the areas around the Gulf of St. Lawrence, the world’s largest estuary, and the outlet of the North American Great Lakes via the Saint Lawrence River into the Atlantic Ocean.
Leif Erikson formed two groups: one to remain at the camp, and the other to explore the lands.
After having spent the winter in Vinland, Leif Erikson returned to the family estate of Brattahlíð in Greenland in the spring of 1000 with a cargo of grapes and timber.
In Greenland, he started preaching Christianity. His father, Erik Thorvaldsson reacted with anger to the suggestion that he should abandon his religion – Norse paganism.
Replica of Tjodhilde’s Church that was built in Brattahlið (Source: greenland.com)
His mother became a Christian and built a church called Thorhild’s Church (actually a small chapel) in Brattahlið.
At odds with both wife and eldest son Leif, Erik attempted a sail to Leif’s Vinland with his youngest son Thorstein. They failed to reach Newfoundland, but the doughty Eric said, “We were more cheerful when we put out of the fjord in the summer; but at least we are still alive, and it might have been worse.”
Erik the Red is last mentioned in the sagas in 1005.
Leif Erickson is last mentioned alive in 1019. By 1025, he installed one of his sons, Thorkell as the chieftain of Eriksfjord (Eiríksfjǫrðr).
None of the sagas mentions Leif Erickson’s death. He must have died in Greenland. Nothing further is known about his family beyond the succession of Thorkell as chieftain.
In the early 1960s, Norwegian explorer Helge Ingstad and his wife, archaeologist Anne Stine Ingstad, identified a Norse settlement located at the northern tip of Newfoundland. They suggested that this site, known as L’Anse aux Meadows, is Leif’s settlement of Leifsbúðir, the first known attempt at founding a settlement by Europeans on the mainland of the Americas.
Leif Erikson had opened the way to America. Vikings ships plied from Greenland to these “new lands” (Newfoundland) during the following years.
According to Brattahlíð lore, Thorvaldur, the brother of Leif Erikson set sail to further explore Vinland. The natives of Vinland, called Skrælings (“stunted”) by the Norse because of their small size, attacked Thorvaldur and his crew. Thorvaldur received a fatal wound and his men buried him in Vinland and returned to Greenland.
According to the “Saga of the Greenlanders,” Leif Erikson’s younger brother Thorstein set sail for Vinland along with his wife Gudrid Thorbjarnardóttir (Guðríður Þorbjarnardóttir) to retrieve his brother Thorvaldur’s body. Losing their way at sea they had to return. At the close of the first week of winter, they landed at Lysufiord, where Thorstein fell ill and died.
After her husband’s death, Gudrid returned to Brattahlíð. She married a merchant named Thorfinn Karlsefni, “a man of good family and good means” and “a merchant of good repute.” After their marriage, at Gudrid’s insistence, the couple set sail to Vinland with a group of sixty men, five women, and various livestock in an attempt to settle down in the camp that Leif Erickson had built some years earlier. They spent three years in Vinland.
In Vínland, Gudrid bore a son, the first European reported to be born in the Western Hemisphere. They named him Snorri Thorfinnsson,
Harassed by the natives, Thorfinn and Gudrid returned with their son to Greenland, where Thorfinn Karlsefni died.
After that, the hostile indigenous people of Vinland thwarted the many attempts by settlers from Greenland and Iceland to found a colony there. The stories of the various Viking expeditions survived in the collective memory of the descendants of those who returned by the 13th century from the North American coast to settle once again in Greenland and Iceland.
The Norse settlements in coastal North America were small. They did not develop into permanent colonies. While voyages, such as to collect timber, are likely to have occurred for some time, there is no evidence of enduring Norse settlements on mainland North America.
Leif Erikson has the honor of being the first European to open the way to America almost 500 years before Christopher Columbus.
For eons, the Americas were a pristine no man’s land. Around 12,000 BC, humans first stepped onto the North American continent. But who were they?
The Clovis people
Approximately 14,000 years ago, humans walked across the Bering Strait from Siberia into Alaska. They were the Clovis people.
The Clovis culture is a prehistoric Paleo-Indian culture, named after distinct stone tools found at sites near Clovis, New Mexico, in the 1920s and 1930s. This culture appears at the end of the last glacial period, roughly around 13,200.
The Clovis people spent the next few thousand years migrating from Alaska to the south and east across North America, and then into South America.
The manufacture of “Clovis points” and distinctive bone and ivory tools characterize the culture of the Clovis people. They are the ancestors of most of the indigenous cultures of the Americas: the Folsom tradition, Gainey, Suwannee-Simpson, Plainview-Goshen, Cumberland, and Redstone.
At the same time as the Clovis people began leaving behind tools, human bones and other evidence of their presence in the northwest, humans were leaving similar items along the New England coastline in the Northeastern United States. It puzzled the historians. They wondered how the Clovis people could trek from both Alaska and New England at the same time?
The answer – two different cultures discovered America: one crossing the frozen Bering Strait, on foot; and the other traveling from Europe to America’s east coast by boat.
Gunnbjørn Ulfsson (circa 10th century), also known as Gunnbjørn Ulf-Krakuson, a Norwegian, was the first European to sight North America. Blown off course while sailing from Norway to Iceland, GunnbjørnUlfsson and his crew sighted islands which he called “Gunnbjarnarsker” (Gunnbjörn’s Skerries) lying close off the coast of Greenland. They did not land on any of those islands. However, Gunnbjørn reported this find.
The exact date of this event is not recorded in the Nordic sagas. Various sources cite dates ranging from 876 to 932, but these must remain little more than guesses, but the early 10th century is more likely than earlier.
Around 978, Snaebjörn Galti (c. 910 – 978) made the first purposeful visit to Gunnbjørn’s islands. According to records from the time, this first Norse attempt to colonize Greenland ended in disaster.
Historians consider Eric the Red, the Viking rover, who soon followed Galti’s attempt, as the first permanent European settler in Greenland.
Eric the Red
According to medieval and Icelandic sagas Erik Thorvaldsson (Eiríkr Þorvaldsson) was born in the Jaeren district of Rogaland in Norway around 950.
He is best known as Erik the Red (Eiríkr hinn rauði). The appellation “the Red” most likely refers to the color of his hair and beard and perhaps also because of his fiery temper.
Erik’s father Thorvald Asvaldsson (Þorvald Ásvaldsson) was banished from Norway for manslaughter. Thorvald sailed West from Norway with his family and settled in Hornstrandir in northwestern Iceland, 175 miles away from Greenland.
Erik married Thorhild (Thjóðhildr), daughter of Jorund Atlisson, and as part of her dowry received land at Eriksstadir in Haukadal where he built a farm.
Around the year 980, the thralls (serfs or slaves) of Erik caused a landslide on the neighboring farm belonging to Valthjof. The landslide buried the home of Valthjof along with him and his family. Eyiolf the Foul, a kinsman of Valthjof in turn killed the thralls. Eric retaliated by killing Eyjolf and Holmgang-Hrafn. Eyjolf’s kinsmen demanded the banishment of Erik from Haukadal.
The Vikings cherished the ornamental beams which were symbols of Viking authority and had religious, mystical, and political significance known as the setstokkr. Erik had inherited his setstokkr which his father had brought with him from Norway. After giving this setstokkr to his friend Thorgest (Þórgestr) to look after, Erik and Thorhild moved to the isle of Öxney off the western Icelandic coast.
After building his new house, Erik went back to Haukadal to get his setstokkr. Thorgest refused to give them back. An infuriated Erik went to Breidabolstad and stole Thorgest’s own setstokkr instead.
Thorgest gave chase. Erik prepared an ambush. In the ensuing skirmish, Erik slew both sons of Thorgest and a few other men.
Thorgest approached the court.
In 981, the thing (Þing), assembly of Thorness resolved the dispute. Erik was banished from both Iceland and Norway, for three years.
Erik the Red had heard about the “Greater Ireland” settlements in Greenland, a small, unprotected Irish settlement in Greenland.
In the spring of 981 he traveled westward in his 100-foot-long ship. It was not a romantic voyage with the urge to discover new lands. It was rather a typical Viking voyage of plunder.
Erik’s party landed near Julianehåb. They arrived too late to reap the reward, for the Irish settlers had already left and mere arctic desolation greeted them.
They spent the first winter on the island of Eiriksey. In spring, he proceeded to Eriksfjord (Eiríksfjǫrðr). They spent the second winter in Eiriksholmar, close to Hvarfsgnipa.
According to the Saga of Erik the Red, Erik spent his three years of exile exploring this land. In the last summer, they explored as far north as Snaefell and into Hrafnsfjord. They even crossed the Davis Strait and reached Baffin Island, then abundant with game.
Erik was much impressed with the resources he found in the land. He was convinced that the new land was better adapted than Iceland for raising stock.
In 985, Erik returned to Iceland after the expiry of his exile period. He wanted to found a colony in the new land he had found. He knew that the success of any settlement in the new land would need the support of as many people as possible.
Erik had great powers of persuasion. He was always boasting and praising the new land he had returned from. To lure potential settlers, Erik on purpose called the land “Greenland” which was a more appealing name than “Iceland”. Many Vikings, especially those living on impoverished lands in Iceland and those that had been victims of a recent famine became convinced that Greenland held great opportunity.
The following year Erik set out from Iceland leading a fleet of 25 ships on course for Greenland. On board were around 500 men and women, various livestock, provisions and gear required to found the settlement in Greenland.
Of the 25 ships only 14 made it to the eastern shore of Greenland – of the other 11, some sank while others turned back to Iceland.
Each sea-captain claimed a fjord to which he gave his name.
Erik the Red and his wife Thorhild took the best fjord. They called it Eriksfjord (Eiríksfjǫrðr). They built the farm Brattahlið near its head (in present-day Qassiarsuk). Here, Erik lived like a Jarl (lord) with his wife and four children: Leif Erikson, Thorvald (Þorvaldr) Eiriksson, Thorstein (Þorsteinn) Eiriksson, and an illegitimate daughter, Freydis Eiríkssdóttir.
Along one side of Eriksfjord was much good pasture. The farm Brattahlið lay on one of the most fertile plains in Greenland. Another large green valley lay behind it.
Erik the Red held the title of the paramount chieftain of Greenland and became both much respected, and wealthy.
Both the Eastern Settlement (the area around present-day Qaqortoq, formerly Julianehåb) and the Western Settlement (around Nuuk or Godthåb, the capital and largest city of Greenland) were presumably established soon.
The Eastern Settlement was about 300 miles south of the Western Settlement. Located near the mouth of Eiriksfjord in the area of Qaqortog, the Eastern Settlement had about 200 farmsteads and supporting facilities.
During the summers, when the weather favored travel, each fjord-based settlement would send an army of men to hunt in Iss Vagr above the Arctic Circle. They hunted food and other valuable commodities such as seals, Walrus tusks and meat from beached whales. In these expeditions, they first met the Inuit people or Skræling.
The settlement flourished, growing to 5000 inhabitants spread over a considerable area along Eriksfjord and neighboring fjords. Groups of people escaping overcrowding in Iceland migrated to Greenland.
In 1002, a group of immigrants brought with it an epidemic that ravaged the colony, killing many of its leading citizens, including Erik the Red.
The Norse colony in Greenland lasted for almost 500 years.
Hugh Herr, an American, born October 25, 1964, a double amputee is building the next generation of bionic limbs, robotic prosthetics inspired by nature’s own designs. Herr is a rock climber, engineer, and biophysicist.
Herr grew up in rural Pennsylvania, and his only dream was becoming a mountaineer. By the time he was 8, being a prodigy rock climber, he scaled the face of the 11,627-foot (3,544 m) Mount Temple in the Canadian Rockies.
In January 1982, the 17-year-old Hugh Herr, acknowledged as one of the best climbers in the United States, and a fellow climber 20-year-old Jeff Batzer ascended a difficult technical ice route in Huntington Ravine on Mount Washington in New Hampshire. They were caught in a blizzard. Disoriented, they wandered through the frozen wilderness. Eventually, they descended into the Great Gulf and spent three nights in −20 °F (−29 °C) degree temperatures. When rescued, both the climbers had suffered severe frostbite and hypothermia. During the rescue attempt, an avalanche killed a volunteer named Albert Dow.
Months of surgeries followed. Unfortunately, both legs of Hugh Herr were amputated below the knee. His companion, Jeff Batzer lost his lower left leg, all the toes on his right foot, and the fingers of his right hand. He did not climb again. He joined the clergy and is now the director of pastoral care at the Lancaster Evangelical Free Church.
After the amputation and rehabilitation, Hugh Herr focused on academics. He earned an undergraduate degree in physics at the Millersville University, and then a master’s degree in mechanical engineering at MIT, followed by a Ph.D. in biophysics from Harvard University.
Soon, an undaunted Hugh Herr using specialized prostheses that he himself designed, was climbing once again, a feat his doctors told him was unthinkable.
Hugh Herr designed and created prosthetic feet with high toe stiffness that made it possible for him to stand on small rock edges the width of a coin. He designed titanium-spiked feet to assist him in ascending steep ice walls. He used the prostheses to alter his height that could range from five to eight feet, to avoid awkward body positions and to grab hand and footholds that were previously out of reach. He created robotic powered ankles because that was the only way for smooth walking.
Using the prostheses, Herr climbed rock cliffs at a more advanced level than he had before the amputation. He became the first person with a major amputation to perform in a sport on par with able-bodied sportsmen.
At present, Hugh Herr is an associate professor in MIT’s Program in Media Arts and Sciences and at the Harvard-MIT Division of Health Sciences and Technology. As the head of the MIT Media Lab’s Biomechatronics group, Herr focuses on the designing of the next generation of bionic limbs and robotic prosthetics inspired by nature’s own designs. He is developing wearable robotic systems that serve to augment the human physical capability. He is rewriting the laws of physiology by redefining what it means to be human.
TED is a nonprofit group devoted to spreading ideas, usually in the form of short, powerful talks. TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today it covers almost all topics — from science to business to global issues — in more than 100 languages.
TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes or less on Technology, Entertainment and Design — plus science, business, global issues, the arts and much more.
In the following video, Dr. Hugh Herr shows his incredible technology in a talk that is both technically and deeply personal. He demonstrates the Biometric technology developed by the MIT Media Lab’s Biomechatronics group with the help of the ballroom dancer Adrianne Haslet-Davis, who lost her left leg in the 2013 Boston Marathon bombing, and performs again for the first time on the TED stage.
Looking deeply inside nature through the magnifying glass of science, designers extract principles, processes and materials that are forming the very basis of design methodology, from synthetic constructs that resemble biological materials to computational methods that emulate neural processes, nature is driving design. Design is also driving nature. In realms of genetics, regenerative medicine and synthetic biology, designers are growing novel technologies not foreseen or anticipated by nature.
Bionics explores the interplay between biology and design. As you can see, my legs are bionic. Today I will tell human stories of bionic integration, how electromechanics attached to the body and implanted inside the body are beginning to bridge the gap between disability and ability, between human limitation and human potential.
Bionics has defined my physicality. In 1982, both of my legs were amputated due to tissue damage from frostbite incurred during a mountain climbing accident. At that time, I didn’t view my body as broken. I reasoned that a human being can never be broken. Technology is broken. Technology is inadequate. This simple but powerful idea was a call to arms to advance technology for the elimination of my own disability and ultimately the disability of others. I began by developing specialized limbs that allowed me to return to the vertical world of rock and ice climbing. I quickly realized that the artificial part of my body is malleable, able to take on any form, any function, a blank slate through which to create perhaps structures that could extend beyond biological capability. I made my height adjustable. I could be as short as five feet or as tall as I’d like. (Laughter) So when I was feeling badly about myself, insecure, I would jack my height up, but when I was feeling confident and suave, I would knock my height down a notch just to give the competition a chance. (Laughter) (Applause) Narrow, wedged feet allowed me to climb steep rock fissures where the human foot cannot penetrate, and spiked feet enabled me to climb vertical ice walls without ever experiencing muscle leg fatigue. Through technological innovation, I returned to my sport stronger and better. Technology had eliminated my disability and allowed me a new climbing prowess. As a young man, I imagined a future world where technology so advanced could rid the world of disability, a world in which neural implants would allow the visually impaired to see, a world in which the paralyzed could walk via body exoskeletons.
Sadly, because of deficiencies in technology, disability is rampant in the world. This gentleman is missing three limbs. As a testimony to current technology, he is out of the wheelchair, but we need to do a better job in bionics to allow one day full rehabilitation for a person with this level of injury. At the MIT Media Lab, we’ve established the Center for Extreme Bionics. The mission of the center is to put forth fundamental science and technological capability that will allow the biomechatronic and regenerative repair of humans across a broad range of brain and body disabilities.
Today, I’m going to tell you how my legs function, how they work, as a case in point for this center. Now, I made sure to shave my legs last night, because I knew I’d be showing them off.
Bionics entails the engineering of extreme interfaces. There’s three extreme interfaces in my bionic limbs: mechanical, how my limbs are attached to my biological body; dynamic, how they move like flesh and bone; and electrical, how they communicate with my nervous system.
I’ll begin with mechanical interface. In the area of design, we still do not understand how to attach devices to the body mechanically. It’s
extraordinary to me that in this day and age, one of the most mature, oldest technologies in the human timeline, the shoe, still gives us blisters. How can this be? We have no idea how to attach things to our bodies. This is the beautifully lyrical design work of Professor Neri Oxman at the MIT Media Lab, showing spatially varying exoskeletal impedances, shown here by color variation in this 3D-printed model. Imagine a future where clothing is stiff and soft where you need it, when you need it, for optimal support and flexibility, without ever causing discomfort.
My bionic limbs are attached to my biological body via synthetic skins with stiffness variations that mirror my underlying tissue biomechanics. To achieve that mirroring, we first developed a mathematical model of my biological limb. To that end, we used imaging tools such as MRI to look inside my body to figure out the geometries and locations of various tissues. We also took robotic tools. Here’s a 14-actuator circle that goes around the biological limb. The actuators come in, find the surface of the limb, measure its unloaded shape, and then they push on the tissues to measure tissue
compliances at each anatomical point. We combine these imaging and robotic data to build a mathematical description of my biological limb, shown on the left. You see a bunch of points, or nodes. At each node, there’s a color that represents tissue compliance. We then do a mathematical transformation to the design of the synthetic skin shown on the right, and we’ve discovered optimality is where the body is stiff, the synthetic skin should be soft, where the body is soft, the synthetic skin is stiff, and this mirroring occurs across all tissue compliances. With this framework, we produced bionic limbs that are the most comfortable limbs I’ve ever worn. Clearly in the future, our clothing, our shoes, our braces, our prostheses, will no longer be designed and manufactured using artisan strategies, but rather data-driven quantitative frameworks. In that future, our shoes will no longer give us blisters.
We’re also embedding sensing and smart materials into the synthetic skins. This is a material developed by SRI International, California. Under electrostatic effect, it changes stiffness. So under zero voltage, the material is compliant. It’s floppy like paper. Then the button’s pushed, a voltage is applied, and it becomes stiff as a board. We embed this material into the synthetic skin that attaches my bionic limb to my biological body. When I walk here, it’s no voltage. My interface is soft and compliant. The button’s pushed, voltage is applied, and it stiffens, offering me a greater maneuverability of the bionic limb.
We’re also building exoskeletons. This exoskeleton becomes stiff and soft in just the right areas of the running cycle to protect the biological joints from high impacts and degradation. In the future, we’ll all be wearing exoskeletons in common activities such as running.
Next, dynamic interface. How do my bionic limbs move like flesh and bone? At my MIT lab, we study how humans with normal physiologies stand, walk and run. What are the muscles doing, and how are they controlled by the spinal cord? This basic science motivates what we build. We’re building bionic ankles, knees and hips. We’re building body parts from the ground up. The bionic limbs that I’m wearing are called BiOMs. They’ve been fitted to nearly 1,000 patients, 400 of which have been U.S. wounded soldiers.
How does it work? At heel strike, under computer control, the system controls stiffness to attenuate the shock of the limb hitting the ground. Then at mid-stance, the bionic limb outputs high torques and powers to lift the person into the walking stride, comparable to how muscles work in the calf region. This bionic propulsion is very important clinically to patients. So, on the left you see the bionic device worn by a lady — on the right a passive device worn by the same lady that fails to emulate normal muscle function — enabling her to do something everyone should be able to do, go up and down their steps at home. Bionics also allows for extraordinary athletic feats. Here’s a gentleman running up a rocky pathway. This is Steve Martin, not the comedian, who lost his legs in a bomb blast in Afghanistan.
We’re also building exoskeletal structures using these same principles that wrap around a biological limb. This gentleman does not have any leg condition, any disability. He has a normal physiology, so these exoskeletons are applying muscle-like torques and powers so that his own muscles need not apply those torques and powers. This is the first exoskeleton in history that actually augments human walking. It significantly reduces metabolic cost. It’s so profound in its augmentation that when a normal, healthy person wears the device for 40 minutes and then takes it off, their own biological legs feel ridiculously heavy and awkward. We’re beginning the age in which machines attached to our bodies will make us stronger and faster and more efficient.
Moving on to electrical interface, how do my bionic limbs communicate with my nervous system? Across my residual limb are electrodes that measure the electrical pulse of my muscles. That’s communicated to the bionic limb, so when I think about moving my phantom limb, the robot tracks those movement desires. This diagram shows fundamentally how the bionic limb is controlled, so we model the missing biological limb, and we’ve discovered what reflexes occurred, how the reflexes of the spinal cord are controlling the muscles, and that capability is embedded in the chips of the bionic limb. What we’ve done, then, is we modulate the sensitivity of the reflex, the modeled spinal reflex, with the neural signal, so when I relax my muscles in my residual limb, I get very little torque and power, but the more I fire my muscles, the more torque I get, and I can even run. And that was the first demonstration of a running gait under neural command. Feels great. (Applause)
We want to go a step further. We want to actually close the loop between the human and the bionic external limb. We’re doing experiments where we’re growing nerves, transected nerves, through channels or microchannel arrays. On the other side of the channel, the nerve then attaches to cells, skin cells and muscle cells. In the motor channels, we can sense how the person wishes to move. That can be sent out wirelessly to the bionic limb, then sensors on the bionic limb can be converted to stimulations in adjacent channels, sensory channels. So, when this is fully developed and for human use, persons like myself will not only have synthetic limbs that move like flesh and bone, but actually feel like flesh and bone.
This video shows Lisa Mallette shortly after being fitted with two bionic limbs. Indeed, bionics is making a profound difference in people’s lives.
(Video) Lisa Mallette: Oh my God. Oh my God, I can’t believe it. It’s just like I’ve got a real leg. Now, don’t start running.
Man: Now turn around, and do the same thing walking up. Walk up, get on your heel to toe, like you would normally just walk on level ground. Try to walk right up the hill. LM: Oh my God. Man: Is it pushing you up? LM: Yes! I’m not even — I can’t even describe it. Man: It’s pushing you right up.
Hugh Herr: Next week, I’m visiting the center’s —
(Applause) Thank you, thank you.
Thank you. Next week I’m visiting the Center for Medicare and Medicaid Services, and I’m going to try to convince CMS to grant appropriate code language and pricing so this technology can be made available to the patients that need it.
Thank you. (Applause)
It’s not well appreciated, but over half of the world’s population suffers from some form of cognitive, emotional, sensory or motor condition, and because of poor technology, too often, conditions result in disability and a poorer quality of life. Basic levels of physiological function should be a part of our human rights. Every person should have the right to live life without disability if they so choose — the right to live life without severe depression; the right to see a loved one in the case of seeing impaired; or the right to walk or to dance, in the case of limb paralysis or limb amputation. As a society, we can achieve these human rights if we accept the proposition that humans are not disabled. A person can never be broken. Our built environment, our technologies, are broken and disabled. We the people need not accept our limitations, but can transcend disability through technological innovation. Indeed, through fundamental advances in bionics in this century, we will set the technological foundation for an enhanced human experience, and we will end disability.
I’d like to finish up with one more story, a beautiful story, the story of Adrianne Haslet-Davis. Adrianne lost her left leg in the Boston terrorist attack. I met Adrianne when this photo was taken at Spaulding Rehabilitation Hospital. Adrianne is a dancer, a ballroom dancer.
Adrianne breathes and lives dance. It is her expression. It is her art form. Naturally, when she lost her limb in the Boston terrorist attack, she wanted to return to the dance floor.
After meeting her and driving home in my car, I thought, I’m an MIT professor. I have resources. Let’s build her a bionic limb to enable her to go back to her life of dance. I brought in MIT scientists with expertise in prosthetics, robotics, machine learning and biomechanics, and over a 200-day research period, we studied dance. We brought in dancers with biological limbs, and we studied how do they move, what forces do they apply on the dance floor, and we took those data and we put forth fundamental principles of dance, reflexive dance capability, and we embedded that intelligence into the bionic limb. Bionics is not only about making people stronger and faster. Our expression, our humanity can be embedded into electromechanics.
It was 3.5 seconds between the bomb blasts in the Boston terrorist attack. In 3.5 seconds, the criminals and cowards took Adrianne off the dance floor. In 200 days, we put her back. We will not be intimidated, brought down, diminished, conquered or stopped by acts of violence. (Applause)
Ladies and gentlemen, please allow me to introduce Adrianne Haslet-Davis, her first performance since the attack. She’s dancing with Christian Lightner. (Applause)

Some say that the United States is a country that tolerates other nationalities. Does it really?
Some states of the United States still incarcerate a high proportion of blacks than apartheid South Africa did. Today the black-white wealth gap in the United States is greater than what it was at the peak of apartheid in South Africa in 1970.
On rare occasions, individual citizens challenged public segregation in the United States, but their effirts had minimal impact on civil rights issues. In some locales, in addition to segregated seating in buses, it could be forbidden for stores or restaurants to serve different races and nationalities under the same roof.
In December 1955 in Montgomery, Alabama, Rosa Parks refused to move to the back of a bus for a white passenger. Parks’ civil disobedience sparked the Montgomery Bus Boycott. This act of defiance by Rosa Parks became an important symbol of the modern Civil Rights Movement, and Parks became an international icon of resistance to racial segregation.
In Alabama, where the vestiges of segregation still linger on, Indian citizens have to be careful while walking on the streets. The case of the 57-year-old Sureshbhai Patel clearly illustrates the attitude of the white segregationists. And, sadly, it is the guardians of peace, who resort to brutality.
The following video includes a footage captured on the morning of February 6, 2015 by the dash cam of a car, shows an inglorious scene of two Alabama police officers using disproportionate force and slamming a frail Sureshbhai Patel to the ground. Sureshbhai Patel was out strolling near his son’s house in Madison, Alabama. He had arrived only the previous day from India to see his 17-month-old grandson. Sureshbhai Patel is now partially paralyzed and hospitalized in a city hospital.
The police officer Eric Parker, who assaulted Patel has been arrested for third-degree assault. Madison City Police chief Larry Muncey has offered apologies to Patel and his family and has said the Federal Bureau of Investigation will look into the incident.
It has a lot to do with the juxtaposition of opposites: the sense of being underground with the light streaming in; the intimacy of being in a cave, yet the columns end up very large, sometimes thirty to forty feet high. – Ra Paulette in an interview, 2014
For the past 25 years, 67-year-old Ra Paulette, an American cave sculptor based in New Mexico has been carving out caves from the sandstone hills of New Mexico. He digs, shovels, scrapes, and bores into hillsides. He then sculpts elaborate artistic spaces inside these caves. He turns the underground sculpted spaces into works of art. And, his caves attract visitors worldwide.
Ra Paulette grew up in La Porte, LaPorte County, Indiana, United States, along the shores of Lake Michigan. In 1985, he moved to the small town of Dixon in Rio Arriba County, New Mexico, near the Rio Grande about 35 miles north of Santa Fe.
A veteran of the Vietnam War, Ra Paulette began creating underground art. When he roamed the rugged terrain of the remote backcountry and found a promising spot on the side of a sandstone cliff he would start digging with his pickaxe. He works with rudimentary hand tools such as shovels, pick axes, and scrapers. Paulette never studied architecture, sculpting or structural engineering in a formal school. He is self-taught.
In 1987 Paulette finished his first cave using a shovel and buckets and a wheelbarrow. He called the “Heart Chamber.” Later on, he described it to a historian as “a secret place for me, a private place, a hermitage.” The Heart Chamber had many visitors and it almost developed into a public shrine. The cave was on public land and he had dug it without permission from the authorities. Fearing it might collapse on a visitor, he buried the chamber and sealed it off.
The Jemez Mountains are a volcanic group of mountains in New Mexico, United States. Located in the rural Ojo Caliente River Valley, approximately halfway between is the Rancho de San Juan, the 225-acre Relais & Chateaux Country Inn and Restaurant. David Heath and John H. Johnson II, the owners of the ranch had moved to the area from California to open the elegant Resort.
In June 1994, Ra Paulette approached the owners of Rancho de San Juan. He showed them pictures of the Heart Chamber and asked them if they would like to commission him to dig a shrine on their property. At first the owners were reluctant. After several months 0f persistence by Paulette, they relented. They wanted their guests to have a view of the surrounding impressive landscape from their ranch. They commissioned Ra Paulette to open the interior of the natural butte. Heath and Johnson paid him between $10 and $16 per hour for his work.
It took two and a half years for Ra Paulette to create the “Windows in the Earth Shrine.” It is a chamber with lofty arched ceilings and imposing columns. Long windows fill the chambers with light. The windows provide a spectacular panorama of the magnificent Jemez Mountains. Inside the sandstone cave, one can enjoy the art created by Ra Paulette. He has carved all sorts of shapes on the interior sandstone walls: scallops, molded curves, smooth ledges, inlaid stones, narrow pods and crusty ledges. There is space to meditate and write. Even high desert weddings take place there.
Later on, Ra Paulette created more than a dozen caves. He spent months and in some cases he toiled for years on each of them.
Needless to say, the work of Ra Paulette was backbreaking. He carved out rooms, connected tunnels, created alcoves and arches, benches, steps, pillars, etc. He decorated the surfaces with sculpted shapes and chiseled ornamental patterns. He broke through walls and ceilings to create windows and skylights to bring in sunlight to the dark underground spaces.
Martha Mendoza, a reviewer in the Los Angeles Times described the caves of Ra Paulette as hallowed places and as a sanctuary for prayer and meditation. Many connoisseurs of art describe the caves of Ra Paulette as works of art.
For thousands of years, indigenous peoples lived in the vast expanse of land that is now known as the United States of America. They developed their own complex cultures before the arrival of the European colonists. The Spanish had early settlements in Florida and the Southwest. The French settled along the Mississippi River and Gulf Coast.
After 1600, most of the colonists in these new-found lands were from England. By the 1770s, there were 13 British colonies along the Atlantic coast east of the Appalachian Mountains. About two and a half million people populated these colonies.
In early 1770s, the British East India Company was in financial difficulties. It held a massive surplus of tea in its London warehouses. The English Parliament presented the Tea Act of 1773 to help the struggling company survive. This Act was also promulgated to undercut the price of tea smuggled into Britain’s North American colonies.
The Tea Act of 1773 granted the British East India Company the right to ship its tea directly to North America. The Company also received the right to duty-free export of tea from Britain. Yet, the tax imposed by the Townshend Acts and collected in the colonies remained in force. The Tea Act received the royal assent on May 10, 1773. (See my article: The Boston Tea Party of December 16, 1773).
The colonies did not send representatives to the British Parliament. Hence, they had no influence over the taxes raised, levied, or how they were spent. So, they objected to the Tea Act. They believed the Act violated their rights as Englishmen in America to be taxed without their consent. They raised the slogan: “NO TAXATION WITHOUT REPRESENTATION.”
In September and October 1773, seven ships carrying East India Company’s tea set sail to the American colonies. The ships carried more than 2,000 chests containing about 600,000 pounds of tea. Four ships were bound for Boston and one each for New York, Philadelphia, and Charleston.
The Americans learned the details of the Tea Act only after the ships were en route. Whigs was a nickname for the Patriots, who sometimes called themselves the “Sons of Liberty”. They mobilized a coalition of merchants and artisans to oppose the delivery and distribution of the inbound tea.
The Whigs began a campaign to raise awareness about the implications of the provisions in the Tea Acts. They opposed the Acts which implicitly agreed to accept the right of taxation by the English Parliament.
Benjamin Franklin said the British were trying to use cheap tea to “overcome all the patriotism of an American”.
Benjamin Rush, a Founding Father of the United States from the state of Pennsylvania, urged his fellow Americans to oppose the landing of the tea. He said the cargo contained “the seeds of slavery”.
On October 16, 1773, Dr. Benjamin Rush, Colonel William Bradford, Thomas Mifflin, Dr. Thomas Cadwalader, and other local leaders and members of the Philadelphia Sons of Liberty organized a meeting at the Pennsylvania State House. They adopted eight resolutions. One resolution stated:
“That the duty imposed by Parliament upon tea landed in America is a tax on the Americans, or levying contributions on them without their consent.”
The most important one read:
“That the resolution lately entered into by the East India Company, to send out their tea to America subject to the payment of duties on its being landed here, is an open attempt to enforce the ministerial plan, and a violent attack upon the liberties of America.”
These declarations, printed in the Pennsylvania Gazette, comprised the first public protest against the importation of taxed tea from England.
In Boston, Whig leader Samuel Adams called for a mass meeting at Faneuil Hall. Three weeks later, on November 5, 1773, at a town meeting at Faneuil Hall the Bostonians adopted the same resolutions that Philadelphians had promulgated earlier. In their resolution the Bostonians declared:
“That the Sense of the Town cannot be better expressed on this Occasion, than in the words of certain Judicious Resolves lately entered into by our worthy Brethren the Citizens of Philadelphia.”
Colonial merchants, some of them smugglers of Dutch tea, joined the Whigs. They played a significant role in the protests because the Tea Act made legally imported tea cheaper. Also, the Tea Act was a threat to put an end to their smuggling business. Other legitimate importers of tea, not chosen as consignees by the British East India Company, also faced financial ruin because of the Tea Act. Most American merchants feared that this type of government-created monopoly might extend to include other goods in the future.
The Whigs convinced, and sometimes harassed the Company’s authorized consignees to resign. They successfully prevented the unloading of taxed tea in three colonies and forced the ships to turn back to England. They could not do so in Massachusetts.
The tea ship Dartmouth arrived in the Boston Harbor in late November, 1773. On November 29, a handbill posted all over Boston, contained the following words:
Friends! Brethren! Countrymen! – That worst of plagues, the detested tea, shipped for this port by the East India Company, is now arrived in the harbor.
That day Whig leader, Samuel Adams called for a mass meeting, at Faneuil Hall. As thousands of people arrived, the meeting shifted to a larger venue – the Old South Meeting House. The assembled passed a resolution, introduced by Adams, urging the captain of the Dartmouth to turn back to England without paying the import duty. Meanwhile, the meeting assigned twenty-five men to watch the ship and prevent unloading of the tea from the ship.
British law required the Dartmouth to unload its cargo of tea and pay the customs duties within twenty days . If the customs duties were not paid within that time, the customs officials could confiscate the cargo.
Royal Governor Thomas Hutchinson refused to grant permission for the Dartmouth to leave Boston without paying the duty. He convinced the tea consignees, two of whom were his sons, not to back down.
Two more tea ships, the Eleanor and the Beaver, arrived in Boston Harbor. Another ship, the William headed for Boston encountered a storm and sank before it could reach Boston.
On December 16th, the last day of the Dartmouth’s deadline to pay the customs duties, about 7,000 people gathered around the Old South Meeting House.
After receiving the report that Governor Hutchinson had refused to let the ships leave, Samuel Adams announced: “This meeting can do nothing further to save the country”.
Immediately, people poured out of the Old South Meeting House. Samuel Adams tried to reassert control of the meeting, but the throng headed out to prepare to take action.
Some donned elaborately prepared Mohawk costumes, disguising their faces, because of the illegality of their protest. Dressing as a Mohawk warrior was a specific and symbolic choice. In the evening of December 16, 1773, they boarded the three vessels – Dartmouth, Eleanor and the Beaver. Over the course of three hours, they dumped 342 chests of tea into the water.
Eventually, the Boston Tea Party proved to be one of the many courses that culminated in the American Revolutionary War.
In most countries, the test for parking is one of the hardest task before getting a license to drive a car. For most of us parking a car might not be the easiest of all manoeuvres. Now, electronic gadgets take over much of the guess work.
At the beginning of last year, Audi, the German car maker whose slogan ‘Leap ahead through technology’ (German: ‘Vorsprung duech Technik‘) demonstrated a car that can park itself without the need for a driver. Audi calls it “Piloted Parking.”
This reminds us of cars from Mr. Q’s lab in James Bond films and Knight Rider’s KITT.
Audi demonstrated its self-parking car in Las Vegas. After getting out of the vehicle, at the click of a button on a smartphone, the car drives off by itself to a nearby parking garage. The car was summoned by pressing another button on the smartphone.
Here is a video clip of the Las Vegas test. The car controlled via a special app moves only in special ‘pedestrian free zones’. But Audi is developing anti-collision technology to be used in a normal car park.
