Chaos. Nonlinear Dynamics

The chemistry of the cosmos today is not what it used to be. The stars and planets and interstellar gas around us are laced with carbon, oxygen, and many other elements heavier than hydrogen and helium - the only substances to have existed for a few hundred million years after the big bang.

A six-legged robot learns different walking styles, which it can then use to adapt to tricky terrain or even flee from the first signs of trouble

A six-legged robot with a "panic mode" is proving to be a whizz at locomotion. When it finds it cannot move freely, the panicky droid scans randomly through the many walking gaits it has taught itself and selects the best for the terrain. That means it can free itself should it get stuck.
