ABSTRACT:
The assembly (10) is a self-propelled conveyor system including a vehicle (12) having wheels (18) and a motor (16) for moving the vehicle (12) along a track (20). The vehicle (12) includes a speed sensor (24) for sensing actual speed of the vehicle (12) and a location sensor (26) for sensing the absolute position of the vehicle (12) along the track (20). A control (22) receives the actual speed and absolute location signals and drives the vehicle (12) at a speed associated with the absolute position, this value being obtained from a memory (32). The control (22) drives the motor (16) at the selected speed with a feedback signal of actual speed wherein the control (22) may adjust the drive signal when actual speed differs from selected speed.
