Fast Company highlights the cheap-for-the-price Phoenix exoskeleton, created by University of California Berkeley professor (and Berkeley Robotics and Human Engineering Laboratory director) Homayoon Kazerooni and a team of his former grad students at SuitX, a company Kazerooni founded in 2013. Set to sell for $40,000 when it goes on sale next month, the Phoenix sounds expensive -- except compared to the alternatives. For paraplegic patients, there are a handful of other powered exoskeletons, but they cost much more, and are engineered for more than the modest goals of the Phoenix, which allows only one thing: slow walking on level ground. That limited objective means that the rig is light (27 pounds), and relatively unobtrusive. Kazerooni says that he'd like the price to go down much further, too, noting that all the technology in a modern motorcyle can be had for the quarter of the price.
A slice: [The] only driving motors in Phoenix are at the hip joints. When the user hits a forward button on their crutches, their left hip swings forward. At this moment, the onboard computer signals the knee to become loose, flex, and clear the ground. As the foot hits, the knee joint stiffens again to support the leg. This computer-choreographed process repeats for the right leg.
As it happens, this hinged knee joint has another benefit. If the wearer hits something midstep, like a rock or a curb, a powered knee would blindly drive the leg forward anyway, likely leading to a fall. The hinge naturally absorbs such resistance and allows the wearer a chance to compensate.Read Replies (0)

mdsolar writes: A former Energy Department employee accused of attempting to infiltrate the agency's computer system to steal nuclear secrets and sell them to a foreign government pleaded guilty Tuesday to a reduced charge of attempting to damage protected government computers in an email "spear-phishing attack." Charles Harvey Eccleston, a former employee at the department and at the independent Nuclear Regulatory Commission (NRC), was arrested March 27 by Philippine authorities after an undercover FBI sting operation. Eccleston, 62, a U.S. citizen who had been living in the Philippines since 2011, was "terminated" from his job at the NRC in 2010, according to the Justice Department. In January 2015, the department said, he targeted more than 80 Energy Department employees in Washington at four national nuclear labs with emails containing what he thought were links to malicious websites that, if activated, could infect and damage computers.Read Replies (0)
