Pictured are a caterpillar (bottom) and a biomimetic soft origami robot (top). Inspired by the motion of caterpillars, Wu et al. fashioned a soft origami robot powered by electrothermal actuation. The lightweight modular design incorporates thermal actuators consisting of layers of liquid crystal elastomer and polyimide. Thermal extension and contraction are achieved through coordinated active and passive units, which mimic caterpillars’ forward crawling and side-to-side steering motions. According to the authors, thermal actuation may aid the design of modular soft origami robots that can grow and adapt. See the article by Wu et al. e2322625121. Image credit: Glaucio H. Paulino.
