How do you teach robots to navigate new places? Study toddlers.

An eerie four-legged robot is shown pacing through the woods with relative ease. But when brought inside and tested in other situations, such as slippery surfaces, it had balance issues and difficulty walking. In one example, when weighted bags were placed on its back, the robot fell over. With Facebook's AI software enabled, it wobbled but managed to stay upright and keep walking when the bags were tossed onto it. There are no cameras on the device. All of the robot's movements were guided by sensors in its feet and various joints, which allow it to experience the world through "touch."
