DARPA Pushes for Fail-Proof Prosthetics

Better prosthetic devices have been a major Pentagon priority for years. Now, they want to make the devices longer-lasting, more reliable and better able to integrate directly with the human brain. DARPA, the military’s risk-taking research agency, is launching the next phase of its Revolutionizing Prosthetics program, which was started in 2000 with the goal of creating a fully-functioning, neurally-controlled human limb within five years. Since then, the agency has made plenty of progress. They’re currently doing human trials of the DEKA Arm , a prosthetic that allows users to complete day-to-day tasks with unprecedented ease. That arm uses a joystick-style interface, with a user tapping commands with their toes to trigger movements with the arm. At Johns Hopkins , DARPA-funded researchers are still working on an arm that uses a 100-sensor neural interface to create a brain-body meld much like what’s inherent in natural limbs. But although DARPA had hoped to have a fully-functional, neuro-prosthetic model ready by 2010, the agency’s researchers have yet to master the integration of human neural pathways with artificial platforms.
