Abstract: A human assisted walking robot formed by a motor, a cargo bin, a pair of legs mounted to the carrier; and a stabilizing support mounted at its proximal end to the carrier and having a wheel rotatably mounted to the distal end. The motor drives the first and second leg members resulting in a walking motion. Each leg is formed by a thigh link and a shank link. A four-bar linkage is coupled between the motor and the thigh and shank of each leg so that rotational motion generated by the motor produces a walking motion by the legs.
