Researchers from Johns Hopkins University and Stanford University have trained a robot to perform surgical procedures using only video recordings. The team used a da Vinci surgical system costing over $2,000,000. It is controlled by a specialist who manipulates instruments to perform various tasks. Using a machine learning method, the researchers taught the da Vinci system to perform 3 key tasks: needle manipulation, tissue lifting, and suturing. As a result, the robotic surgeon not only performed them successfully at a human level, but also learned to correct its own mistakes. Hundreds of videos taken from wrist cameras mounted on da Vinci's arms during surgeries were used to train the robotic surgeon. The researchers are currently working on training the robot to perform a full surgery
