Liquid crystal elastomers(LCEs) are one of the most attractive materials for the soft-robotics due tothe stimuli-responsive properties. Actuation of LCEs can be programmed by regulatingorientation of LC mesogens and adopting different types of geometries in diversedimension. Among the diverse type of shape, filament-shape which have one-dimensionalform is effective in designing actuation that can operate complex locomotiondue to their high degree of freedom in three dimensions. Herein, we demonstrateautonomous rolling locomotion in helical LCE filament in response to a thermalstimulus, which locomotion path is precisely controlled by the diameter andperiod and also temperature. Based on the locomotionof helical filament, we demonstrated the ability of exploring complex mazespaces by autonomous modification of path in external thermal stimulus. The autonomousmodified, battery-free and wireless soft robots can provide new concept ofapplications for spatial exploring task. |
