| Research Abstract |
We have been studying the hyper flexible morphing mobile robot that has flexible gel states and can change its shape via a magnetic field. It can also change its stiffness by using hot-ice phenomenon. The basic performances and characteristics, movements, and abilities to change shape and stiffness of the prototypes have been confirmed through experiments. To expand the gel robot's motion range, we manufactured the omnidirectional X-Y stage to move neodymium magnets in any direction for the dexterous control of the magnetic field. This omnidirectional X-Y stage is composed of multiple spur gears those rotating axes are perpendicular to each other and the planar omnidirectional driving gears to move neodymium magnets with them smoothly. We also fabricated and tested a novel gel material that can change its shape and stiffness without any magnetic fields. Many types of gel robotic actuators were tested including robotic grippers and flexible omnidirectional driving gears.
