1. A surgical system comprising:

  • a robotic system comprising;

    a control unit;

    a shaft portion that includes at least one electrically conductive elongated member outer tube that is electrically coupled to the control unit;

    a drive shaft disposed at least partially within the at least one electrically conductive outer tube and being operably coupled to a portion of said robotic system for transmitting control motions from the robotic system, and wherein the surgical system further comprises;

    a surgical instrument comprising an end effector that is configured to be operably coupled to the at least one electrically conductive outer tube and said drive shaft for receiving said control motions from said robotic system, said end effector including at least one sensor that is electrically insulated from the at least one elongated electrically conductive outer tube such that the at least one elongated electrically conductive outer tube wirelessly radiates communication signals from the control unit to the at least one sensor and can receive wirelessly radiated communication signals from the at least one sensor.
