Light-Controlled Soft Jumping Robot Based on Electronic Fluorinated Liquid

随着科技的迅速发展，光控软体机器人吸引了越来越多国内外研究者们的兴趣。本文灵感主要来自最常见的果蝇幼虫的跳跃运动机制，制备并提出了一种使用电子氟化液加入小型腔室封装后，拥有跳跃运动能力的光控软体机器人器件。使用功率约为1 W的远程红外激光，对封装了电子氟化液的腔室进行照射，一段时间后，由于内部液体气化为气体，腔室内部体积迅速膨胀并使腔室整体发生形变，从而产生较大的膨胀应力。通过这一膨胀应力，软体机器人(长：5厘米；宽：0.9厘米；重：0.75克)的两边磁铁间的距离会逐渐变大，直到两边的磁铁无法吸附在一起，软体机器人的头部与尾部迅速解开，尾端会对基底进行快速、较大力量的拍打，软体机器人在4秒的时间内，能够跳跃至约40厘米高的位置。基于电子氟化液的光控软体跳跃机器人在智能运动器件、无线操控机器人领域拥有很大的应用价值，本文提出的特殊结构的光控腔室制备方法也验证了连续激光热解技术用于制作小型柔软器件的可行性和便捷性。In the era of rapidly advancing technology, light-controlled soft robots have garnered increasing attention from researchers. Inspired by the jumping mechanism of gall midge larvae, this study proposes a light-controlled soft robotic device based on electronic fluorinated liquid that exhibits remarkable jumping capabilities. When irradiated by a remote infrared laser (power: ~1 W) targeting the liquid-filled chamber containing electronic fluorinated fluid, the photo-responsive chamber undergoes rapid expansion and deformation within milliseconds, generating substantial expansive stress. Driven by this stress, the distance between the magnetic components (length: 5 cm; width: 0.9 cm; weight: 0.75 g) at both ends of the soft robot progressively increases, causing instantaneous disengagement between the head and tail sections. The subsequent forceful impact of the tail against the substrate surface propels the robot to achieve rapid jumping motion, reaching a vertical height of approximately 40 cm within 4 seconds. The developed light-controlled soft jumping robot demonstrates significant potential for applications in soft robotics and actuator systems. Furthermore, the proposed fabrication method for the photo-responsive chamber validates the feasibility and efficiency of continuous laser pyrolysis technology for manufacturing miniaturized functional devices.
