A Snake-Inspired Multi-Segmented Magnetic Soft Robot Towards Medical Applications

Magnetically-actuated soft robots have potential for medical application but require further innovation on functionality and biocompatibility. In this letter, a multi-segmented snake-inspired robot with dissolvable biocompatible segments is designed. The actuation response under external magnetic field investigated through simulations experiments. A dissolve-controllable mixture of gelatin, glycerol water (GGW) in mass ratio 1:5:6 used to form the structure robot. dissolution GGW mucus tested. Magnetic cubes made silicone rubber mixed ferromagnetic particles are achieve snake-like motion influence rotating field. tested different magnitudes frequencies ability navigate obstacles, move over ground as well oil-coated surface, dissolve release drug demonstrated combination design materials illustrates such applications.
