Abstract: A walker for a handicapped person has a pair of base rails juxtaposed, and a pair of front posts extend therefrom. Each front post is attached to a front of a respective rail. A first pair of rotation-changeable motors drives a pair of actuators, initially pointing upwardly. A first pair of gear reduction devices, which in combination with a pair of rear posts, can be rendered tiltable, has respective input shafts coupled to respective output shafts of the motors. The pair of tiltable rear posts are extendable or retractable by rotation-sense selection of the first pair of motors. A pair of crutch supports are in contact with the rear posts, Which fit under the armpits of the handicapped person. A pair of levers which extend outwardly and downwardly from the pair of crutch supports, respectively, are bent rearwardly, and equipped with handles.
