1. A surgical system, comprising:

  • an electromechanical arm configured for movement in multiple axes;

    an electromechanical tool having an instrument shaft and an end effector formed thereon, the electromechanical tool being configured to be mounted on the electromechanical arm, and the electromechanical tool being configured to move with or relative to the electromechanical arm and apply energy to tissue engaged by the end effector; and

    a controller operatively coupled to the electromechanical arm and the electromechanical tool, the controller configured to retard advancement of the electromechanical tool toward a tissue surface based on a sensed temperature of the end effector, wherein the controller is configured to retard advancement of the electromechanical tool when the end effector is within a predetermined threshold distance from a tissue surface, and wherein the predetermined threshold distance varies based on the temperature of the end effector.
