Cheetah robot breaks the speed record

This robot set a new speed record for legged robots, we all know that robots on wheels are a lot faster. This robot is moving like the fast-running animals and especially cheetah. The record is now 18 miles (29 kilometers) per hour with the previous record being set on 1989 with 13.1 mph. It is running by flexing and un-flexing its back and if you have seen documentaries the first image that pops in your mind is the wild predators of the nature. The creator of this robot is Boston Dynamics of Waltham which works with US department of defence (DOD).
