For roughly three decades, medical robots have assisted surgeons in the operating theater. They provide a steady hand and can make tiny incisions with pinpoint accuracy. But as robotics improve, a new question has emerged: How should autonomous robots be treated? The US Food and Drug Administration (FDA) approves medical devices, while medical societies monitor doctors. A robot that can operate on its own falls somewhere in between. To help, Science Robotics has produced a scale for grading autonomy in robot-assisted surgery. If adopted, it could help regulators decide when and how machines should be treated like humans.
