For nearly the whole of the 20th century, bipedal [[robot]]s were very difficult to construct and [[robot locomotion]] involved only wheels, treads, or multiple legs. Recent cheap and compact computing power has made two-legged robots more feasible. Some notable biped robots are [[ASIMO]], [[HUBO]], [[MABEL (robot)|MABEL]] and [[QRIO]]. Recently, spurred by the success of creating a fully passive, un-powered bipedal walking robot,<ref>{{Cite web |url=http://ruina.tam.cornell.edu/hplab/pdw.html |title=Passive Dynamic Walking at Cornell |website=Ruina.tam.cornell.edu |access-date=2013-04-30 |url-status=live |archive-url=https://web.archive.org/web/20131107235643/http://ruina.tam.cornell.edu/hplab/pdw.html |archive-date=2013-11-07 }}</ref> those working on such machines have begun using principles gleaned from the study of human and animal locomotion, which often relies on passive mechanisms to minimize power consumption.
