Surgical robots can be broadly classified into three categories on the basis of how surgeons interact with them:
- Supervisory-controlled robot systems in which the surgeon plans the operation, and the robot then carries it out autonomously under the supervision of the surgeon;
- Telesurgical (master-slave) systems in which the surgeon (master) remotely controls the robots actions (slave);
- Handheld shared-controlled systems in which the surgeon and robot share control of the instrument.
