Legless soft robots capable of rapid, continuous, and steered

Index

Abstract

Jumping is a crucial locomotion function for terrestrial robots, enabling them to navigate varied terrains. This paper introduces a tethered, legless soft jumping robot driven electrohydrostatically, capable of rapid, continuous, and steered jumping. The robot, weighing 1.1g and measuring 6.5cm, achieves a jump height of 7.68 body heights and a continuous forward jumping speed of 6.01 body lengths per second. Utilizing two actuator units, it demonstrates rapid turning at 138.4° per second, effectively navigating various obstacles. This research establishes a foundation for electrohydrostatic actuation in agile, fast, multimodal soft robots.
