Physical intelligence uses material properties and structural design for actuation. This study designed an asymmetrical cylinder with metal needles, springs, and inorganic salt. When heated, it generates a twisting force that induces rolling by shifting the center of gravity. Cylindrical liquid crystal elastomers (CLCEs) were used as wheels in a cargo transfer device. Additionally, actuators capable of grabbing were developed using particle-doped CLCEs with salt and PDA particles. These asymmetrical CLCEs show potential for soft robot applications, including AI components and polymeric light/heat control systems. BackgroundFew reports exist on shifting the center of gravity in liquid crystal elastomers with dopants, enabling rotation or bending. MethodsTo fabricate CLCEs with asymmetric constructions, different dopants and particles were mixed with an LCE mixture and injected into a cylindrical glass substrate for polymerization. Significant findingsThis study demonstrates the creation of CLCEs with shifted centers of gravity through various dopants and twisting angles. These elastomers can roll, making them ideal for cargo transfer, with movement speed controllable by adjusting temperature, dopants, and twisting angles. They also hold promise for developing robotic arms that can grasp objects, controlled through heat or light exposure.
