Abstract
Abstract A shopping cart for use in supermarket stores that is propelled by a battery driven electric motor. The cart is in the form of a frame supported by four wheels, with an open shopping basket mounted in the forward and intermediate section of the frame and a bench seat mounted over the rear wheels. A foot platform, open at each side, separates the basket from the seat. The cart is controlled by two foot pedals, one of which controls the steering of the wheels under the seat with the other foot pedal controlling the direction of travel and the start and stop of cart travel. A baby seat is hinged inside the shopping basket to a wall of the basket.
