END EFFECTOR COMPENSATION OF A ROBOTIC SYSTEM

Abstract:

One embodiment comprises a method of operating a robotic system. The method comprises defining a Tool Center Point (TCP) for an end effector of the robotic system, providing a primary control plan that defines a tool path for the end effector, where the tool path has a plurality of pre-defined TCP positions. The method further comprises providing a secondary control plan that defines operation of the end effector at the plurality of pre-defined TCP positions, and determining a deviation between a pre-defined TCP position of the end effector and an actual TCP position of the end effector during implementation of the primary control plan by the robotic system. The method further comprises modifying the secondary control plan for the end effector based on the deviation during the implementation of the primary control plan by the robotic system.
