Liquid crystal elastomers are among the best candidates for artificial muscles, and the materials of choice when constructing microscale robotic systems. Recently, significant efforts are dedicated to designing stimuli‐responsive actuators that can reproduce the shape‐change of soft bodies of animals by means of proper external energy source. However, transferring material deformation efficiently into autonomous robotic locomotion remains a challenge. This paper reports on a miniature inching robot fabricated from a monolithic liquid crystal elastomer film, which upon visible‐light excitation is capable of mimicking caterpillar locomotion on different substrates like a blazed grating and a paper surface. The motion is driven by spatially uniform visible light with relatively low intensity, rendering the robot “human‐friendly,” i.e., operational also on human skin. The design paves the way toward light‐driven, soft, mobile microdevices capable of operating in various environments, including the close proximity of humans.

轻型，卡特彼勒启发的微型点动机器人

液晶弹性体是人造肌肉的最佳候选者，也是构建微型机器人系统时的首选材料。最近，人们致力于设计刺激响应的执行器，这些执行器可以通过适当的外部能源再现动物软体的形状变化。但是，将材料变形有效地传递到自主的机器人运动中仍然是一个挑战。本文报道了一种由整体式液晶弹性体薄膜制成的微型微动机器人，该机器人在可见光激发下能够模仿毛毛虫在不同基底（如火焰状光栅和纸张表面）上的运动。该运动由强度相对较低的空间均匀可见光驱动，使机器人“人性化”，即在人体皮肤上也可使用。该设计为光驱动，柔软的移动微型设备铺平了道路，该微型设备能够在包括人类附近在内的各种环境中运行。
