Is Leonardo da Vinci's robot surgery done by a robot or by a doctor? Will the robot break down during the operation?

Da Vinci surgical robot, although called robot, is completely controlled by doctors! The robot is just a surgical assistant system. Some people will worry that the robot is out of control in the body. Actually, I worry too much. Leonardo da Vinci's surgical robot could not carry out any activities without the participation of doctors. You can't program and run by yourself. After all, it is a tool, not a person. In use, the surgeon operates the mechanical arm through the handle and pedal before sitting through the console. In addition, there is a design that reflects the safety of patients: on this console, there are sensors on both sides of the scope, which can monitor whether the surgeon is paying attention to the surgical field of vision. Once the surgeon leaves the console, the mechanical arm will be locked immediately to prevent the possibility of misoperation. I'm happy to answer your question.
