A controlled motion system, which has a plurality of movers that are movably mounted on a track for moving along a path. Active and reactive elements are associated with the movers and track, and are configured for driving and controlling the position of the movers along the path. A plurality of track modules are assembled as the track, with each track module comprising a plurality of the active elements. A controller is operatively associated with the active elements for controlling the driving of the movers, and a position sensor is associated with the track and configured for sensing the true absolute position of each mover along the path and transmitting position information on the position of each mover to the controller. Preferably, the position sensor comprises module position sensors configured for sensing the position of the movers along the path and transmitting position information on the position of the movers to the controller, and each track module comprises at least one of the module position sensors. |
