Any object that does not form part of your system and which your system interacts with is an actor. So if your program merely sends commands to or receives them from the robot then I would say that the robot is probably an actor. If, on the other hand, your program forms part of the robot then it should not be an actor. Personally, from your description, I would say that the surgeon, camera and robot are probably all actors.
