It's been a good couple of weeks for Boston-area robotics startups: two young companies have recently closed on significant venture rounds. One of them, iWalk, is commercializing prosthetic limb technology developed at MIT's Media Lab under Dr. Hugh Herr, himself a double amputee.
Herr, an avid rock climber, lost both legs to frosbite after a climbing accident at age 17. He immediately began building his own prosthetic limbs to enable him to get back into climbing. As he started his academic research career he dedicated his efforts to developing prosthetic limbs using robotics. Among his projects is a powered prosthetic ankle and foot called the PowerFoot One.

I had the opportunity to hear Dr. Herr speak at an MIT robotics conference last November. At the time, I knew nothing of his background or research. Halfway in to the presentation as he was describing his research, he rolled up the cuffs of his slacks to reveal metal and electronics. Until that point I'd had no idea he was a double amputee; as he'd walked to the front of the room, his gait -- though not completely normal -- was so smooth, I'd never have guessed he was dealing with anything but a couple of stiff joints.
Herr's work, including an assistive device for patients with muscle control difficulty, has been commercialized by other companies in the past. But iWalk -- who has tested prototypes with veterans and other disabled patients -- appears to be focused entirely on the technology coming out of Herr's research, and the $20M Series-B investment is just what they need to start serious production.
