Aghhh! Run!

The Cheetah robot – developed by Pentagon military research agency DARPA – can run at 18mph: just 5mph faster than the previous record set in 1989, but plenty quick enough to run most humans down prior to destroying them.

DARPA sez:

The robot’s movements are patterned after those of fast-running animals in nature. The robot increases its stride and running speed by flexing and un-flexing its back on each step, much as an actual cheetah does.

The current version of the Cheetah robot runs on a laboratory treadmill where it is powered by an off-board hydraulic pump, and uses a boom-like device to keep it running in the center of the treadmill. Testing of a free-running prototype is planned for later this year.
