    Abstract: A remote controlled golf bag cart is described. The cart consists of two rear wheels and a front wheel mounted on a tricycle-type chassis. The rear wheels are coupled to a battery operated electric motor which drives them simultaneously. The front wheel is controlled by a motor driven worm device which turns the front wheel to the right or the left. A remote control is used to operate the motor which typically has a rheostat and to turn the front wheel to the left or right.
