Our self-designed cable drive system allowed the suit’s motor to be mounted on the
user’s back, instead of attaching directly to the actuated joint. This non-localized
actuation system was especially novel, as it allowed us to use a more powerful motor,
enabling greater lifting strength for the user. This method also produces a more mobile
exoskeleton, as the centrally located motor is less bulky than arm-mounted designs. To
transmit this force, the flexible cable drive provides the strength that users need while
allowing unimpeded motion throughout the human range of motion. Non-localized
actuation allows disabled persons to regain their former strength and flexibility without
sacrificing mobility.
