One of the world's fastest robots mimics roach legs for speed


The hated cockroach has been the scourge of restaurants and big cities throughout history. But now a clever roboticist may have finally found a use for the pests by developing a way to mimic their legendary crawling speed.
Berkeley Ph.D. student Duncan Haldane wanted to explore the benefits of creating bio-inspired mechanisms to increase the terrestrial locomotion of robots. His research resulted in the creation of the VELOCIRoACH, a tiny robot that, according to Haldane, is the fastest running robot to date, relative to size. Weighing just 30 grams, the 10-centimeter-long hexapedal millirobot can travel as fast as 26 body lengths per second.
The key to the robot's speed is the way its legs are designed like a real cockroach's, allowing the VELOCIRoACH's legs to make contact with the ground at a rate of roughly 15 times per second. And get ready for the real creep out factor, the VELOCIRoACH even mimics the way a real cockroach stops and starts in rapid bursts to move around or over obstacles, always keeping at least three legs on the ground.
