Description
Liu Yang and five co-authors built a soft magnetic robot whose body can be reprogrammed with light and which can feel its own motion, in a 2026 paper. Ordinary magnetic soft robots have fixed magnetization, so they cannot change how they move, and they carry no senses. The team's robot uses custom microspheres whose magnetic particles heat under near-infrared light, letting domains be rewritten as the material melts and resets.
One robot can thus roll, creep, or walk on multiple legs, with the multi-legged rolling mode fastest at about 27 millimeters per second. A printed spiral sensor made of liquid metal reports movement and terrain through capacitance patterns, stable over a hundred cycles. In a simulated stomach, the robot told its own gaits apart.
