Abstract: A teleoperated material handling system 100 includes a teleoperation terminal 10 for collecting mechanical inputs from a teleoperator and converting to operation commands, a material handling vehicle 20 with a load engaging device 21, a visual capturing module 22 for capturing video imagery in front of the material handling vehicle, a communication module 30 for establishing a communication link with the teleoperation terminal for transmitting the video imagery to the teleoperation terminal and receiving the operation commands, and a control module 40 for controlling operations of the material handling vehicle and the load engaging device. The system further includes an assistive module 50 providing an assistive indicator to the teleoperator through the teleoperation terminal, the assistive indicator 51 is dynamic with respect to changes in the operation commands, and provides visual guidance for the teleoperator in maneuvering the load engaging device.
