Inspired by dinosaurs, Raptor is a fast-running biped robot developed by the MSC Lab at Korea Advanced Institute of Science and Technology (KAIST). It has two under-actuated legs and a tail inspired by velociraptors, providing stability over high obstacles.

The Raptor robot runs at a speed of 46 km/h (28.58 mph) on a treadmill with off-board power. That’s faster than the fastest human, the Olympic sprinter Usain Bolt, whose top speed has been estimated at 43.92 km/h — but not as fast as Boston Dynamics’ Cheetah, at 47 km/h (29.2 mph).
