• But evaluating and training these systems remains difficult.
• Physical robotic platforms are expensive to operate, experiments are slow to reproduce, and failures can damage instruments or biological material.
• Conventional simulators provide a safer alternative, but surgical scenes are exceptionally difficult to model: deformable tissue, fine instrument interactions, specular surfaces, sutures, needles, smoke, and occlusions all matter.
• World foundation models offer a different path.
• Instead of manually authoring every object and physical interaction, they learn visual dynamics directly from synchronized video and robot kinematics.
