Hstar proposes an integrated reconfigurable non-treadmill rehabilitation robot (RehaBot) system using SEA (series elastic actuators) that a) allows multiple reconfigurable and progressive rehabilitation training procedures for upper and lower limbs, b) provides telepresence rehabilitation training consultation and remote supervision, c) creates gait retraining scenarios for ambulatory training in variable terrains (e.g. stair climbing, ascending a ramp, curve road), d) supports advanced safety and intervention through haptic feedback and real-time monitoring, e) realizes compact and multifunction platform integration. No robotic system currently exists that would meet all of these needs. Our primary innovation is a reconfigurable haptic feedback non-treadmill rehabilitation robotic system using built-in safety actuator technology SEA. Our technology also includes virtual reality, programmable and reconfigurable training procedures under variable terrain scenarios such as a selected set of terrains for walking and different tasks for arm reaching and grasping. The system supports progressive training via patient monitoring, computer control and performance optimization and enhances rehabilitation for patients who suffer neurological and muscular injuries or impairments. . The RehaBot uses a non-treadmill robotic training platform in control of the lower limbs which facilitates the simulation of training on variable terrains. The system will also provide upper limb robot training functions.
