HAL® For Living Support Single Joint Type is a single motor unit that can be attached to the knee or elbow that weighs 1.5 kg (3.3 lb). The unit comes with a custom palm hand controller. Similar to the larger HAL, the exoskeleton is controlled with BES (bioelectrical signals). The motor unit has 120 degrees of maximum rotation.
This assists flexion and extension exercises with a small power unit that was specially developed. The lightweight system of only 1,500g [assisting part] significantly reduces burden of daily transportation and handling of the device.
