Intuitive Surgical is a California-based company that makes teleoperated robots for minimally invasive surgery. Using a remote haptic interface, a surgeon can perform surgery using the robotic interface while small end effectors do the actual work inside a patient across the room (or on another continent). These interfaces are incredible—they give the operator a lot of feedback for accurate control, and at the same time filter out the slight shakiness inherent in even the most steady of human hands. Children’s Hospital Boston has become one of the foremost users of the DaVinci robot, with a great overview here.
