Robots: improving nature
A robotic scalpel made in the Politechnical University of Catalonia adapts to heartbeat and makes the surgeon to operate with greater precision because it has the feel of operating a stopped heart. A submarine robot that can rescue a black box at 500 meters depth, the Girona 500, and a small slave who cleans the house floor. How do the robots? How do they know where they are? What mechanisms make them as accurate? Do they come to improve on nature?
