Robots made out of soft, flexible materials are useful for helping with some surgical procedures and handling fruits and vegetables. However, because they are soft, they are often prone to damage from sharp objects that can destroy them. Researchers at the Vrije University of Brussels, though, have created soft robots that can heal themselves, thanks to the use of an elastomer, which is an elastic polymer. When heated, the molecular bonds that keep the elastomer together loosen and begin to reform back to their original cubelike shape. Watch this video to learn more.
