As exciting as it is to watch Olympic sprinters tear down the track, the truth is that running fast for short distances is just not really human beings' thing. Usain Bolt, the fastest human ever to walk the planet, has reached a top speed of 27.78 miles per hour, which is an amble to a cheetah or a gazelle. Heck, your dachshund can almost certainly outrun you, even with its stubby little legs. What gave our ancestors an evolutionary advantage was their stamina, the ability to chase down prey by running and running until the poor wildebeest ran out steam and dropped.
The bright side of this story is that in the not-too-distant future, robots will be able to hunt and capture your slowpoke self without too much trouble, should the authorities determine that you have a suspicious bulge in your pocket or you need to be punished for jaywalking. Boston Dynamics, a robotics company that uses your tax dollars (in the form of grants from DARPA, the Defense Advanced Research Projects Agency) to make crazy advanced robots that mimic animals in all kinds of interesting ways, just announced that their Cheetah robot has reached a speed of 28.3 miles per hour, faster than any human. What's different about it is that it has legs, not wheels, potentially making it (and robots like it) highly maneuverable. Gaze upon it and tremble:
According to the agency, "DARPA intends to test a prototype on natural terrain next year, but for now Cheetah runs on a treadmill in a lab to allow researchers to monitor its progress, refine algorithms and maintain its moving parts." For now.
