受到自然掌握空气-水界面运动的生物的启发，我们开发并建造了一种自供电、远程控制的冲浪机器人，能够通过控制释放异丙醇，利用表面张力修改进行推进和转向，从而穿越这一边界。在此过程中，我们设计并实施了新颖的释放阀和转向机构，最终使冲浪者具有独特的能力。我们的机器人长度约为 110 毫米，移动速度可达每秒 0.8 个身体长度。有趣的是，我们发现机器人的线速度与推进剂的释放速率遵循1/3幂律。额外的机动性测试还表明，机器人在转弯时能够承受 20 mm s−2 的向心加速度。在这里，我们深入讨论了机器人冲浪者的设计、开发、性能、整体功能和最终限制。
Inspired by creatures that have naturally mastered locomotion on the air–water interface, we developed and built a self-powered, remotely controlled surfing robot capable of traversing this boundary by harnessing surface tension modification for both propulsion and steering through a controlled release of isopropyl alcohol. In this process, we devised and implemented novel release valve and steering mechanisms culminating in a surfer with distinct capabilities. Our robot measures about 110 mm in length and can travel as fast as 0.8 body length per second. Interestingly, we found that the linear speed of the robot follows a 1/3 power law with the release rate of the propellant. Additional maneuverability tests also revealed that the robot is able to withstand 20 mm s−2 in centripetal acceleration while turning. Here, we thoroughly discuss the design, development, performance, overall capabilities, and ultimate limitations of our robotic surfer.
