Now Porsche is pioneering a new generation of robot, one that can work side-by-side with humans. "People and robots will co-operate," says the director of vehicle project and factory structure planning, to build car bodies in Porsche's main factory at Zuffenhausen, near Stuttgart The new robot's metal muscles wear a sensitive skin. Using capacitive sensing, the skin can feel when a human is nearby or makes contact. The robot slows when it senses it's close to a worker and stops if they touch. Capacitive sensing is the technology used on smartphone, tablet and some high-end car infotainment system screens. While the robot handles heavy lifting, its human workmate can simultaneously take on tasks that demand dexterity, flexibility and intelligence.
