Abstract

Kirigami, a technique that transforms 2D sheets into complex designable 3D sculptures, is often used in paper art. In article number 1906233, Yu-Chieh Cheng, Hao Zeng, and co-workers implement kirigami in light-responsive thin-film liquid-crystal network actuators. A versatile 3D shape-shifting and multigait rolling robot capable of light-steered 2D motion is demonstrated.
