7. The da Vinci® Surgical System
Only da Vinci overcomes the limitations of both traditional open surgery and conventional minimally invasive surgery. The da Vinci System is a sophisticated robotic platform designed to expand the surgeon’s capabilities and offer a minimally invasive option for major surgery.
With da Vinci, small incisions are used to introduce miniaturized wristed instruments and a high-definition 3D camera. Seated comfortably at the da Vinci console, your surgeon views a magnified, high-resolution 3D image of the surgical site.

Scenario
Companion robots can help people with day-to-day tasks that they might have difficulty completing on their own. One example is the Care-O-bot that was developed in Germany ( In this scenario, the robot is helping someone make dinner.

The Beacons
In our lab, the stove and the plate are simulated by two infrared emitting beacons - a red one representing the stove and a green one representing the plate. Your robot’s task is to shut down the red beacon, and move the green one across the starting line.
RED Beacon - representing the stove
GREEN Beacon - representing the plate
