Robosaur roams with spring in its step.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 Massachusetts Institute of Technology, at Cambridge; coeducational; chartered 1861, opened 1865 in Boston, moved 1916. It has long been recognized as an outstanding technological institute and its Sloan School of Management has notable programs in business, has been developing Troody--his mobile model of a Troodon, a small, possibly feathered feath·ered adj. 1.

For one thing, Troody relies on springs for muscles instead of the stiff gears used so far in humanoid robots  It has been suggested that Android & Actroid be merged into this article or section. . So, the device walks with a
more "biological" gait, Dilworth says. Moreover, he adds, the
robosaur's resilient control system enables it to negotiate
irregular terrain better than the humanoid robots do.
