没有腿，还能跳3米高的软体机器人

Core Insights - A team of engineers from Georgia Tech has developed a soft robot inspired by the jumping mechanism of nematodes, which can leap up to 3 meters high despite lacking legs [1][3]. Group 1: Robot Design and Mechanism - The soft robot measures 12.7 centimeters and is constructed from silicone rods with a built-in carbon fiber spine, allowing it to jump forward and backward [1]. - The jumping mechanism of nematodes involves a three-stage process: formation of a circular structure, creation of a knot structure, and expansion of the circular structure to release stored elastic potential energy [5][6]. - Nematodes can jump to a height 20 times their body length, which is analogous to a human jumping three stories high while lying down [3][4]. Group 2: Research Findings and Future Applications - The research team utilized high-speed cameras to analyze the jumping dynamics of nematodes, leading to the creation of a prototype soft robot that mimics these behaviors [6]. - The reversible knot structure allows nematodes to store more energy for jumping, enabling rapid energy release within one-tenth of a millisecond [6]. - Future research may explore the potential of knot instability in other soft robot applications, such as crawling, swimming, or grasping tasks, aiming to develop robots with higher flexibility and adaptability for complex environments [6].
