A robot has performed realistic surgery on its own with 100% accuracy, researchers have announced.

In a “major leap” towards using more robots in operating theatres, a machine trained on the videos of surgeries was able to remove a gallbladder from a life-like patient.

The robot was said to have operated with the expertise of a skilled human surgeon, according to Johns Hopkins University researchers in the US, even during unexpected scenarios typical in real-life medical emergencies.

The robot was able to respond to and learn from voice commands from the team, just like a novice surgeon working with a mentor.
