Abstract
A steering mechanism for a remotely-controlled golf caddie having a drive motor coupled to a steering assembly by a non-positive coupling. The non-positive coupling between the drive motor and the steering assembly allows the steering assembly to disengage from the drive motor when the caddie runs into an obstruction. Also, the steering mechanism uses a potentiometer assembly for allowing the caddie to center itself after receiving a command to turn left or right.
