Ahn, Chihyung published the artcileBioinspired Design of Light-Powered Crawling, Squeezing, and Jumping Untethered Soft Robot, Quality Control of 7575-23-7, the main research area is light powered soft robot squeezing crawling jumping.
Light has been recently intensively explored to power robots. However, most existing light-driven robots have limited locomotion modalities, with constrained locomotion capabilities. A light-powered soft robot with a bioinspired design is demonstrated, which can crawl on ground, squeeze its way through a small channel, and jump over a barrier. The arch-shaped robot is made up of liquid crystal elastomer-carbon nanotube composite. When a light source with a power intensity of around 1.57 W cm-2 is scanned over the surface of the robot, it deforms and crawls forward. With an increase in the light scanning speed, it can deform sufficiently to pass through a channel 25% lower than its body height. Subjected to light irradiation, it can also deform to a closed loop, gradually store elastic energy, and suddenly release it to jump over a wall or onto a step quickly, with a jumping distance around eight times its body length and jumping height around five times its body height. Math. models for quant. understanding the multimodal locomotion of this light-powered soft robot are also presented.
