The robotic beast sounds like a swarm of bees, and its mincing gait makes it look more like a show poodle than a truly large dog, meaning it's probably not all that stealthy or fast. But the goal of the 240-lb. (109 kilograms) behemoth isn't to be quiet or quick; it's to carry about 100 lbs. (45 kg) so troops don't have to shoulder their own loads. However, in 2015, the military seemed less enamored of the idea, saying the size and noise would give away soldiers' positions, according to Military.com.
