由沸水驱动的软体机器人Soft Robots Powered By Boiling Water
➀ 科英布拉大学的研究人员开发了一种新型软体执行器，利用沸水产生蒸汽驱动运动，无需高压或外部气泵，结构简单且可扩展。
➁ 该执行器仅需24伏电压即可工作，提供超过50牛的力，压力速率为100 kPa/s，经过千次循环测试仍保持稳定，性能优于传统设计。
➂ 原型机器人（如抓取器和四足机器人Bixo）展示了其在真实环境中的应用潜力，例如抓取物体和攀爬树干，为低成本和户外无泵系统提供了创新方案。
➀ Researchers at the University of Coimbra developed a novel soft actuator powered by boiling water, converting water into steam via an embedded heater to generate motion, offering simplicity and scalability without pumps or high voltage.
➁ The actuator operates at 24V, delivers over 50N of force, and achieves rapid pressure build-up (100 kPa/s), demonstrating durability through 1,000+ cycles and outperforming traditional designs in speed and reliability.
➂ Prototype robots, including a gripper and a climbing robot (Bixo), showcase real-world applicability for tasks like object manipulation and navigating unstructured environments, highlighting safe, low-cost, and pump-free solutions.
