Bioinspired robot STAR

Researcheras at the Biomimetic Millisystem Lab, UC Berkeley, have developed a six legged bioinspired, 12cm long, robot, named SPAR (Sprawl Tuned Autonomous Robot) The robot can vary its sprawl angle in order to adapt to different surfaces. The robot, can achieve legged performance over rough surfaces and obstacles, using a high sprawl angle, and nearly wheel-like performance over smooth surfaces for small sprawl angles. By changing the sprawl angle it can climb over obstacle or crawl underneath them. STAR can run at 5.2m/s (43 body lengths/second, Froude number 9.8) over a smooth surface which makes it the fastest untethered crawling robot. Check out the video below for its crawling performance.
