These videos from 2014 have been making the rounds on the science side of social media, as the spherical walking robot catches the eye of fans and designers. The MorpHex experiment, built by YouTuber Kåre Halvorsen a.k.a. Zenta, can roll along or walk with its many legs. His website, last updated in November 2016, shows that he was working on a different gait algorithm for the next version of the robot, a black-legged, 3D-printed model.
