CLOSED LOOP SOLUTION FOR LOADING/UNLOADING CARTONS BY TRUCK UNLOADER

A truck unloader for unloading cartons from a carton pile includes a controller with a detection system configured to periodically receive one or more images from a vision system and a processor subsystem in connection with the detection system. The processor subsystem configured to calculate a distance from at least a portion of the truck unloader to the carton pile based on the one or more images and advance the truck unloader to perform a sweeping operation based on the distance in an instance in which the distance satisfies a predefined distance threshold. The processor subsystem further configured to monitor a torque input received as a feedback from the one or more sensors while performing the sweeping operation, wherein the sweeping operation is configured to continue until the torque input exceeds a predefined torque threshold.
