System and Method for Determining Real-Time Orientation on Carts in an Independent Cart System

A system and method of determining orientation of a physical location on a cart or end effector located on the cart in an independent cart. system receives a feedback signal from a sensor on the cart, A multi-axis device may generate three or more signals corresponding to X, Y, and Z axes orientations. Processing may be performed on the signals to generate a value of yaw, pitch, or roll of the cart. The feedback or processed signals are transmitted from the mover to a remote device external from the track. The real-time orientation information may be used to implement closed-loop control of an actuator mounted on or external to each cart as the cart travels along the track, Power for the devices on the mover may be provided by a battery mounted on the cart or by a wireless power transfer system.
