- R.U.R. versus Q.U.R.
R.U.R. created the term “robot” and the robot uprising meme, but Q.U.R. may be more relevant to robotics.
- Pneumatic soft robots take a step toward autonomy
A four-legged soft robot walks, rotates, and reacts to environmental obstacles by incorporating a soft pneumatic control circuit.
- Soft pumps for soft robots
A light and portable soft electro-pneumatic pump could power future soft robots.

About The Cover

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. This month's cover is a photograph of a Drotman et al. legged soft robot (see also the Focus by Rajappan et al.) [CREDIT: DROTMAN ET AL./SCIENCE ROBOTICS]
