B60W 40/11

Abstract:

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.

Abstract:

An independent cart system includes an inductive link for contactless power transfer between a track and each mover as the mover travels along the track. A system for contactless data transmission between movers and a controller in the independent cart system includes a transmitter and/or receiver mounted on each mover and a complementary receiver and/or transmitter mounted on a track. The transmitter receives data to be transmitted across the inductive link and modulates a voltage present on either the primary or secondary winding to which it is coupled. The modulated voltage present on one winding induces a corresponding modulation on the voltage present on the other winding. A receiver operatively connected to the other side of the inductive link detects the modulated voltage and decodes the data from the modulated voltage received across the inductive link.
