Abstract: A system for performing operations on a work center disposed on a drill rig floor includes a robotic system having a base disposed on a track for movement thereon, a robot arm supported on the base, and one or more end effector tools selectively attachable to an end of the robot arm. A control system has a robot controller in communication with the robotic system. The robot controller is configured to command the robotic system to enter a mode for performing a selected operation, command the robot arm to engage one of the one or more end effector tools related to the selected operation from a tool storage, command the robotic system to move along the track to a position adjacent to the work center, and command the robotic system to perform the selected operation at the work center using the robot arm and the engaged end effector tool.
