Continuous and programmable photomechanical jumping by using topological transitions of liquid crystalline polymeric film |
| 초록 |
In this study, we demonstrate a photomechanical jumping soft robot capable of continuous and programmable jumping motions without external intervention through on-demand patterning and bidirectional actuation-light irradiation. A soft robot with bistable 3D monoclastic structures is formed by inscribed 270° super-twisted nematic liquid crystal molecular geometry, and it effectively accumulates and instantaneously releases photo-generated energy during the topological transition between the two monoclastic structures to realize a high-performance jumping motion. The implemented soft robot has excellent jumping motility (15.5 BL and 880 BL/s for jumping height and take-off velocity, respectively) among lightweight jumping robots, and can stably overcome large obstacles through the real-time continuous programming.
