Abstract: A motion controller for a motor-driven transportation truck or trolley with a steering pole that can be swivelled about a horizontal axis attached to a steering shaft or a steering frame and is provided with means for setting the direction of motion and the speed, characterized in that the steering pole is equipped with a sensor means providing an output signal that depends not only on the magnitude of the force applied to the steering pole, but also on whether this force is a push or a pull, and that the system also comprises a feed back controller unit that sets and/or regulates the speed and the direction of rotation of the driving motor according to this output signal.
