Torso Control

Rewalk features stabilizing crutches, motorized gears that move the legs, and a computer-equipped backpack holding a battery that powers the device for three to four hours. Motion sensors and onboard processing monitor the wearer’s upper-body movements and center of gravity; when the person shifts his or her torso, the device steps appropriately.
