This remarkable looking little robot is using what would be called muscle memory in humans to adapt to travel over rough terrain. Resembling a scorpion, it is designed to control chaotic movements and essentially make its motions non-chaotic. What this means is that the hexapod robot can move autonomously over a rugged surface. You can see video on the Scientific American site and read the rest of the story there too.
"Bernstein Center for Computational Neuroscience researcher Poramate Manoonpong and Max Planck Institute for Dynamics and Self-Organization researcher Marc Timme are leading a project that has created a six-legged robot with one CPG that can switch gaits depending upon the obstacles it encounters."
