DARPA touts its Cheetah as the world’s fastest running robot, after it hit 18mph on a treadmill. Even more surprising, “Boston Dynamics engineers said previously that they see no reason why their bio-inspired ‘bot can’t run as fast as their flesh-and-blood counterparts someday; that’s something like 70 miles per hour.” Continue reading to see it in-action.

We’re clearly not there yet, but Cheetah does appear to be hitting its stride, flexing and un-flexing its spine as it moves just as a real cheetah does, increasing its stride and running speed in the process. Later this year Cheetah will come out of the lab and perform its first untethered, free-running tests.
