Surgical robot

Today's AI technology could help robots get the hang of conducting complex surgeries. Researchers have taught a robot surgical system to expertly perform a bunch of surgical tasks as capably as human doctors, simply by training it on videos.

At its core, this system uses a "simple" cross-spherical gear paired with a monopole gear to control pitch, roll, and yaw. With clever gearing, coupling, and sliding motions, however, the ABENICS gear is extremely precise in its movements.

Sony has shown off its new surgical robot doing some super-precise work sewing up a tiny slit in a corn kernel. It's the first machine of its kind that auto-switches between its different tools, and has successfully been tested in animal surgery.

Robotic surgical systems such as the da Vinci X are very impressive, with their two arms that are controlled by the surgeon's two hands. An experimental new system takes things even further, though, by adding two more arms controlled by the user's feet.

Researchers at MIT have developed a handheld robot that can help minimally trained responders to control severe internal bleeding in victims of traumatic injury, by helping them insert a needle and catheter into a major blood vessel.

While robotic laparoscopic surgical systems do make certain procedures safer and less invasive, those systems are still operated by human surgeons. Now, however, a surgical robot has performed a delicate operation entirely on its own.
