ABSTRACT:
A look-ahead sensor attached to the its effector end deviates upon each control action upon the robot toward a new position along the seam path. The chord across the seam path from the present effector end to the contemporaneously sensed seam path location is determined and used with the present orientation of the effector end to determine an additional yaw angle compensating for the deviation. As a result, the look-ahead sensor is constantly brought back on track.
