HDT is working under contract to Johns Hopkins University/Applied Physics Laboratory (JHU/APL) to develop the world’s most advanced prosthetic arm. This program, sponsored by DARPA for the benefit of our returning soldiers, aims to develop a neurally-controlled arm with 21 degrees of freedom that will mimic the movement of a natural limb and allow the user to have a sense of touch, temperature and spatial location. For its part, HDT is leading development of the electromechanical arm and is developing novel components including motors, drivetrains, sensors, and controllers that will meet the challenging weight, performance, and power requirements of this program. Beyond this program, HDT is applying advanced electromechanical and systems engineering to a number of related areas. Our areas of pursuit include medical and assistive devices as well as robotic applications—such as bomb disposal—where a dexterous robotic arm under teleoperated control allows explosive ordnance disposal technicians to work remotely, thus reducing their exposure to dangerous situations.
