Kirigami, a technique that transforms 2D sheets into complex designable 3D sculptures, is often used in paper art. 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.
