Amphibian-Inspired Locomotion Strategy for a Slime-Based Magnetic Soft Robot

Amphibian taxa have adapted to thrive within demanding aquatic and terrestrial habitats. Leveraging their specialized anatomical features and distinctive modes of locomotion, amphibians present captivating paradigms for the emulation of bioinspired robotics. Robotics scholars exhibit profound interest in replicating their mechanisms. Nevertheless, the replication of amphibious motion necessitates produce automated actuation, which naturally powered by chemical energy converting mechanical energy process in animals. Prior research endeavors addressed this challenge through the development of rigid robotic systems employing integrated servomotors and intricate mechanical components, which limit the compliance of the robot design and complicate the robot control. In this study, we present research that bridges the remote magnetic robotics control approach and soft slime material to create a finger-tip-sized bioinspired magnetic soft robot (MSR), inspired by the mudskipper. This design has a simpler control method and an appearance more similar to the creature. The MSR with 3 cm length can recreate the terrestrial locomotion of a mudskipper under an ∼46 milliteslas (mT) single rotating
