pigrabbitbear writes "The Boston Dynamics Cheetah just clocked a 28.3 miles per hour sprint on a treadmill, and it's heading outdoors soon. At that speed, it could edge out the world's fastest man, Usain Bolt, in a dead sprint. (Bolt peaked at 27.78 miles per hour in his world-record-setting 100-meter dash back in 2009.) 'To be fair, keep in mind that the Cheetah robot runs on a treadmill without wind drag and has an off-board power supply that it does not carry,' admitted Boston Dynamics in a press release. 'So Bolt is still the superior athlete.' Nevertheless, the team hopes to drop these implements and have a freestanding speed bot by early next year. They're calling that model the WildCat."
