Technique uses magnets, light to control and reconfigure soft robots

Science Daily  August 2, 2019 A team of researchers in the US (North Carolina State University, Elon University) has developed a technique that allows them to remotely control the movement of soft robots, lock them into position for as long as needed and later reconfigure the robots into new shapes. They used soft robots made of a polymer embedded with magnetic iron microparticles. Under normal conditions, the material is relatively stiff and holds its shape. However, when the material is heated using light from an LED the polymer becomes pliable the shape of the robot can be changed by remotely […]
