摘要： Electric vehicles provide shoppers with a motorized shopping cart that can be moved and steered via a hand controller. A base has four castor type wheels, a rechargeable battery, a control box housing a CPU, a right angle motor, and a large turning gear attached to its underside. A small turning gear connects the right angle motor to the large turning gear. A drive motor, drive belt, drive shaft, and drive wheels are mounted on the large turning gear. Front rails and clips are attached to the front of the base. A rear support with an oxygen tank holder is attached to the rear of the top of the base. Telescoping side rails connect the front rails to rear rails with latches attached to the rear support. A joystick-type controller is suspended between the front rails. A pressure sensor is attached to the base's top.
