Drill floor grafter robot

A system for performing one or more operations on a work center disposed on a drill rig floor, the system comprising:

• (a) a plurality of robotic systems each 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;
• and
• (b) a control system having a robot controller in communication with each of the plurality of robotic systems, the robot controller being configured to:
• (1) command at least a subset of the plurality of robotic systems to enter a mode for performing a selected operation,
• (2) command at least one robot arm from the at least a subset of the plurality of robotic systems to engage one of the one or more end effector tools related to the selected operation from a tool storage,
• (3) command at least one of the at least a subset of the plurality of robotic systems to move along its respective track to a position adjacent to the work center, and
• (4) command the at least one of the at least a subset of the plurality of robotic systems to perform the selected operation at the work center using the at least one robot arm and the engaged end effector tool.
