JoeRobe (207552) writes "Researchers at Harvard have developed a pneumatically-controlled rubber robot that combines undulation and quadrupedal "crawling", allowing it to maintain a low profile while moving. In a paper in published in PNAS, they describe it as "A soft robot, composed exclusively of soft materials (elastomeric polymers), which is inspired by animals (e.g., squid, starfish, worms) that do not have hard internal skeletons." The robot is solely powered by relatively low pressures (10 psi), and controlled by 5 pneumatic actuators. The research was funded by DARPA."
