Article Summary
The common cockroach may make your skin crawl, but it turns out the household pest is the perfect model for miniature legged robots. That's why Duncan Haldane and his colleagues at the University of California, Berkeley, have been studying the six-legged pests to improve their millirobots. Their latest creation, the VelociRoACH, is made primarily out of cardboard and measures just 10 cm long, yet it can run 2.7 meters per second, making it the fastest robot of its size, capable of covering 26 times its body length in a single second.
