For the first time, a two-legged, nonhumanoid robot has walked completely on its own, says the machine's inventor.

For the past 5 years, Peter Dilworth of the Massachusetts Institute of Technology has been developing Troody-his mobile model of a Troodon, a small, possibly feathered beast that lived some 70 million years ago. Soon, says Dilworth, larger, faster, feather-covered versions of the robosaur will be scurrying around museums and other entertainment venues.

Besides mimicking the way these birdlike dinosaurs probably walked, the current, 4.5-kilogram model might open new directions for designers of independent walking machines.
