Hardly A Vehicle, MIT's Electric Cheetah Is Still Impressive

While plug-in cars remain a small niche, electric power is displacing internal combustion in a completely different type of "vehicle."

Meet MIT's battery-powered robotic cheetah.

The school's Biometrics Lab built it to study and replicate the movements of animals. Normally, these types of robots are powered by gasoline engines, but this one uses electricity.

It was previously thought that internal combustion was the only way to get the power density needed to keep a robot moving, but MIT researchers developed an electric motor that's just as affective.

In tests on an indoor track, the cheetah achieved speeds of 10 mph, although its designers told MIT News (via The Verge) it can reach a top speed of 30 mph.

The cheetah can also operate untethered, as demonstrated in the above video. The sight of it trotting around MIT's campus is probably one of the stranger things you'll experience today.
