O mundo está estranho

Eu sabia que alguma coisa estava estranha hoje no café da manhã quando meu pão caiu com a manteiga virada pra cima. Aí eu vi esse video e entendi.

"BigDog is the alpha male of the Boston Dynamics family of robots. It is a quadruped robot that walks, runs, and climbs on rough terrain and carries heavy loads. BigDog is powered by a gasoline engine that drives a hydraulic actuation system. BigDog's legs are articulated like an animal’s, and have compliant elements that absorb shock and recycle energy from one step to the next. BigDog is the size of a large dog or small mule, measuring 1 meter long, 0.7 meters tall and 75 kg weight."
