Abstract: Systems and methods for calibrating the location of an end effector-carrying apparatus relative to successive workpieces before the start of a production manufacturing operation. The location calibration is performed using a positioning system. These disclosed methodologies allow an operator to program (or teach) the robot motion path once and reuse that path for subsequent structures by using relative location feedback from a measurement system to adjust the position and orientation offset of the robot relative to the workpiece. When each subsequent workpiece comes into the robotic workcell, its location (i.e., position and orientation) relative to the robot may be different than the first workpiece that was used when developing the initial program. The disclosed systems and methods can also be used to compensate for structural differences between workpieces intended to have identical structures.
