Google's dog robot looks too real for comfort when getting kicked
The 160-pound, four-legged Spot is remarkably agile. It navigates an office on its own, then heads outside to climb a steep hill and a flight of stairs. Spot safely makes its way over rough terrain, which it navigates with the help of its head-mounted sensor. At one point the developers pair Spot with the original Big Dog, which Spot basically humiliates.
