<p>In a laser based alignment system a laser sensor tool comprising a laser emitter and detector element can be gripped by a gripper unit of a robotic arm and used to automatically align the robotic arm with a work surface. A landmark on the work surface can be identified by scanning the work surface with the laser sensor in an X Y plane. A center point of the landmark in the X Y plane can be determined to align the gripper unit with the work surface in the X Y plane. The robotic arm can be calibrated on a Z axis by moving the gripper downward in a z direction until the gripper unit contacts the work surface.</p> |
