ONLINE COVER Untethered Soft Robots Walk This Way. Pneumatic soft robots typically require bulky electromechanical components, such as pumps and valves, to achieve legged locomotion. To simplify the design of untethered quadruped robots, Drotman et al. use fluidic circuits, rather than electronic circuits, to achieve programmable locomotion in their robot. Specifically, a bioinspired gait pattern is achieved using a soft ring oscillator that produces rhythmic motions analogous to biological central pattern generator neural circuits found in nature.
