Cheetah Robot is a fast-running quadruped developed by Boston Dynamics with funding from DARPA. It just blazed past its previous speed record, getting up to 28.3 mph, about 0.5 mph faster than Usain Bolt’s fastest 20 meter split. This version of the Cheetah Robot runs on a treadmill with offboard power. Testing on an untethered outdoor version starts early next year.
