摘要

近年来，由柔性材料制成的仿生爬行机器人受到了广泛的关注。然而，现有的多方向爬行机器人的解决方案主要集中在复杂的驱动模式上。这项研究探索了由近红外（NIR）光驱动的无脊椎爬行动物启发的软爬行机器人。将聚n -异丙基丙烯酰胺（PNIPAM）与多壁碳纳米管（MWCNTs）巧妙结合，制备了具有优异光响应性能的复合水凝胶。在近红外光驱动下，爬行机器人的平均速度为0.17 mm/s。它可以执行复杂的任务，如沿着预定的轨迹爬行，穿越障碍物，并通过近红外光遥控穿越迷宫。该设计对于推进柔性爬行机器人具有重要意义，为近红外光驱动仿生机器人的研究提供了有价值的见解。

Soft crawling robots inspired by invertebrate reptiles: Fabricated with PNIPAM/MWCNTs composite hydrogel and driven by near-infrared light for multi-directional locomotion

Bioinspired crawling robots fabricated from flexible materials have received considerable attention in recent years. However, existing solutions for crawling robots capable of multi-directional locomotion primarily focus on the complex driving mode. This study explores invertebrate reptiles inspired soft crawling robots driven by near-infrared (NIR) light. A composite hydrogel with excellent photo-responsive properties is prepared by ingeniously combining poly(N-isopropylacrylamide) (PNIPAM) with multi-walled carbon nanotubes (MWCNTs). The crawling robot, when driven by NIR light, achieves an average speed of 0.17 mm/s. It can perform complex tasks such as crawling along a predefined trajectory, crossing obstacles, and traversing mazes via remote control with NIR light. This design holds significant significance for advancing flexible crawling robots and provides valuable insights for the research of bionic robots driven by NIR light.
