Yikes!

Like its biological model, the flic-flac spider, the Festo BionicWheelBot can both walk and roll. Together with its discoverer, Professor Ingo Rechenberg, the Festo bionics team has used these unique movement patterns and turned them into a technical masterpiece. This is the work of Festo's Bionic Learning Network.

Hat tip to erco (Eric Ostendorff) on the Parallax Forums. Don't know what is spookier, the real spider or the robot!
