1. A system for cyclical robotic vehicle body assembly with robot temperature calibration, comprising:

  • a robot having an arm for mounting an end effector capable of operating on a positioned vehicle body workpiece and having a positioning target;

    a controller for initially operating the robot so its arm positions the end effector immediately adjacent the vehicle body workpiece in an almost ready work position in preparation for each cycle of operation; and

    a laser sensor for sensing the location of the positioning target on the end effector in the almost ready work position and generating a position signal the controller uses to operate the robot and move its arm and the end effector thereon to a final temperature compensated work position for operation on the vehicle body workpiece in a temperature calibrated manner.
