Here is a soft robot capable of detecting when and where it is damaged to heal itself on the spot. Cornell University engineers used fiber-optic sensors with LED lights that can detect changes on the surface of the robot. As explained on Techxplore, a rapid healing polyurethane urea elastomer was also used.
