Robo Spiders - Multilegged Mechanical Marvels

"Wired.com has a fun gallery of robotic spiders and critters. This one, created by Stanford mechanical engineer Sangbae Kim, was based on a cockroach. It has an aluminum chassis, an electronic motor, and a power-transmission system that allows it to move up to about seven and a half feet per second." http://www.wired.com/gadgetlab/2010/04/gallery-spider-robot/all/1
