The Learning Process: Imitation and Beyond

The research team equipped the existing da Vinci Surgical System with a machine-learning model that analyzes surgical procedures recorded by cameras mounted on the robot's instruments. This model, inspired by advanced AI language models, processes both visual and kinematic data to learn precise movements for tasks such as needle manipulation, tissue handling, and suturing 1
