Ever heard of the Boston BigDog? No, it’s not a new gourmet sandwich—it’s “the most advanced quadruped robot on earth,” the alpha male of the Boston Dynamics family of robots, designed to walk, run and climb on rough terrain, and carry heavy loads. The name is misleading; the BigDog looks more like a headless deer or donkey than a dog, and it’s certainly not anything you’d want sleeping at the foot of your bed, or hanging around your home. In short, the Boston BigDog is very creepy indeed.
