The Body Electric. Uncomfortable shoes. Painful artificial limbs. When technology meets biology, the interface is rarely flawless. An associate professor of media arts and sciences and leader of the Biomechatronics Group in MIT. But more than highlighting a single project, Herr. As both a rock climber and a user of prostheses, Herr has direct experience with frustratingly poor prosthetic designs. His lab is working to understand the tricks the human body uses for moving efficiently, and then translating that knowledge into robotic devices that can not only restore function to those who have lost it but enhance normal human capabilities. When he was young, that intense focus was directed at one thing: climbing.

Body Electric may refer to these artworks, all named after 'I Sing the Body Electric', an 1855 poem from Leaves of Grass by the American poet Walt Whitman. This disambiguation page lists articles associated with the title Body Electric. If an internal link led. His academic interests were, he readily admits, nonexistent. In 1. 98. 2, when he was 1. Herr and a friend were caught in a blizzard while climbing Mount Washington in New Hampshire. They were stranded for three nights before being rescued; one man who was trying to rescue them died. His first prostheses were temporary ones with plaster sockets, and he was instructed not to walk without crutches or another support: the plaster would shatter under his full weight. Later he got permanent prostheses made of wood, rubber, and plastic, but they were stiff and painful. ![]() Yet Herr found that he could still excel in the vertical world of rock climbing. In high school, he had trained in tool and die machining at a vocational school; shortly after returning home from the hospital, he set up a workshop in the garage and put those skills to work designing and building his own prosthetic limbs for rock and ice climbing. Climbing is a sport in which the typical human body can feel awkward, as anyone who has tried to balance on a small foothold or wedge a foot into a crack can attest. He created tiny feet that could balance on a whisper- thin ledge, and hatchetlike blades that could fit into a crack. Soon enough, Herr began climbing harder routes than he. So although Herr had never intended to go to college, a few years after his accident he decided to give it a try, earning a bachelor. His thesis project involved the unusual idea of developing an elastic suit to make vertical climbing easier: the motion of reaching up to grab a handhold stretches the elastic, and its stored energy is then used to aid the more tiring motion of pulling the body upward. His lab is still working on the idea today. For his Ph. D in biophysics at Harvard, he developed a numerical model to describe how a horse runs and established prin. He also worked in MIT. The lab was then led by Gill Pratt . When Herr graduated, Pratt hired him as a postdoc. Herr worked with Pratt to develop a computer- controlled knee joint that uses a magnetorheological fluid. When Pratt left MIT in 2. Herr took over the lab, which eventually became the Biomechatronics Group within the Media Lab. The Science of Walking. Visitors to the Biomechatronics Group, which fills half of a large open room on the Media Lab. The lab, which is typically packed with students and postdocs working on projects, is strewn with computer parts, coffee cups, wires, rolls of tape, random tools, and plastic molds of human feet. At the center of the space is a raised platform with a treadmill and a set of hip- high parallel bars. Ten cameras trained on the platform capture the motions of subjects as they run and walk on the treadmill. Walking, though a seemingly simple act, is still largely mysterious, using energy in a very economical manner that is difficult to re- create in robotics. Though researchers have been able to simulate human walking well enough to create walking robots like those used in DARPA. It will take a few more years, Herr says, to understand walking well enough to program robots and develop prosthetic devices that efficiently replicate human function. These walking and running devices designed in Herr. It is the first foot and ankle prosthesis that behaves, as he puts it, more like a motorcycle than a bicycle, meaning that it puts energy into the system rather than relying solely on human power. In human walking, the calf muscle and the ankle joint contribute the most power. The Bi. OM T2 uses a battery to power a system of microprocessors, sensors, springs, and actuators; the joint provides stiffness during a heel strike to absorb shock, then power to help propel the lower leg up and forward during a step. They also designed it to minimize the battery at the calf, to keep it from getting in the way of dance steps. The goal of such devices is to make prostheses more natural and, by lowering the energy costs of walking, reduce joint stress and fatigue. But bringing bionic devices into the clinic is not easy. Bob Emerson, a prosthetist at A Step Ahead Prosthetics who helps connect patients to research projects in Herr. ![]() ![]() He says it takes vision and persistence to drive major technological innovations in such a small and specialized market. There are still drawbacks to current bionic designs. So how you attach the machine world to that is a really hard problem. Now he is going a step further, collaborating with surgeons and other researchers on ways to allow bionic limbs to be controlled directly by the nervous system, which he hopes to demonstrate in a human in the next few years. Whereas brain- machine interfaces would require invasive surgery for brain implants, he wants to connect electronic devices to the peripheral nerves at the site of the injury, allowing people to control bionic limbs with their existing nerves and potentially even perceive sensations in the limb. Amputation, which is currently a fairly crude surgery, might become a sophisticated procedure of setting up the body to interface with a bionic limb. Extending Human Capability. Along one wall of the Biomechatronics Group lab, wheeled shelves known as the . While the collection of prosthetic devices his lab has already produced is impressive, Herr isn. His lab is also working on technologies that could enhance normal human function, allowing us to walk or run faster, carry more weight, or climb more easily. The dessert cart holds early designs for wearable exoskeletons that would allow people to commute to work on foot as quickly as they might on a bicycle, or carry heavy loads without getting tired. Herr climbs in Shawangunk, New York, in 1. Building an exoskeleton that makes movement easier is challenging. Luke Mooney, a graduate student in the Biomechatronics Group, says that many people think . But he recently worked with Herr on a far more minimalistic approach, focusing solely on providing mechanical power to the ankle to reduce the energy it needs for walking. Their prototype, a hiking boot attached to a brace on the lower leg and powered by a wearable battery pack, is the first exoskeleton that can actually lower the metabolic costs of walking, as demonstrated in a study published this May in the Journal of Neuro. Engineering and Rehabilitation. While some researchers and engineers gloss over the social implications of their work, he has become an outspoken champion for the ways that technology can improve the body. Part of that inspiration comes from Herr. Once he realized he could climb with prosthetic legs, he began celebrating them rather than hiding them, painting them bright colors. Today, he sometimes wears trousers cut off at the knees, making his prostheses visible. Herr has never been concerned with appearing to have . Many people want to camouflage their prostheses, he says, because they associate looking normal with being attractive. His sense of attractiveness was shaped by climbing; as an athlete, he always felt that sexiness was determined by ability more than looks. In 1. 98. 6, Herr became the second person to do a free climb of a 1. Washington state called City Park, at the time considered the hardest such climb in the country. When another climber ascended it in 2. Herr. He sees parallels with how the world responded to Olympic runner Oscar Pistorius, a double amputee who was accused of cheating when he used his prosthetic legs to compete with able- bodied athletes. An artificial limb that makes no attempt to look like a human limb might appear ugly, he says, but .
