Towards Robots with Artificial Skin

“Sensitive synthetic skin enables robots to sense their own bodies and surroundings – a crucial capability if they are to be in close contact with people. Inspired by human skin, a team at the Technical University of Munich (TUM) has developed a system combining artificial skin with control algorithms and used it to create the first autonomous humanoid robot with full-body artificial skin.” (Press Release TUM, 10 October 2019) The robot skin consists of hexagonal cells which are about the size of a two-euro coin. Each of them is equipped with a microprocessor and sensors to detect contact, acceleration, proximity, and temperature. “Such artificial skin enables robots to perceive their surroundings in much greater detail and with more sensitivity. This not only helps them to move safely. It also makes them safer when operating near people and gives them the ability to anticipate and actively avoid accidents.” (Press Release TUM, 10 October 2019) The artificial skin could become important for service robots of all kinds, but also for certain industrial robots (Photo: Department of Electrical and Computer Engineering, Astrid Eckert).
