A Johns Hopkins robot known as SRT-H removed a gallbladder by itself with 100% accuracy after watching surgery videos. It identified arteries, clipped ducts, cut tissue, and even adapted when the visuals changed mid-procedure. It followed voice commands like "grab the gallbladder head" and adjusted in real-time, just like a human trainee. It exhibited the expertise of a skilled human surgeon, even during unexpected scenarios typical in real-life, medical emergencies. The surgery was done on a life-like model, not a real person.
