Abstract
A system for adjusting the position of a load supported on a conveyor cart includes a driven lift mechanism for controlling height and a turntable for controlling rotational orientation. The cart may, alternately or in addition to the above mechanisms, include a gimbal mechanism for rotational adjustment about multiple axes. A processor on the cart provides actuation and control of the mechanisms. An ID card reader on the cart senses ID tags for determining when the cart is adjacent particular locations. Data representing desired load position at the locations is stored either in a memory device or by the ID tag for relay to the processor on the cart via the ID tag reader. A system level controller provides a centralized storage location for desired load position data for communication to a plurality of conveyor carts through a communication link that includes radio frequency modems.
