A Dog’s Love Can Show Robots How to Love Us, Too

Any dog owner can tell you that there’s no love like the one a pup gives you. The way they wag their tail when you come home from work after a long day. The way they get excited when you bring out the leash to take them for a walk, or a tennis ball to toss around. The guilty look they give you when they sneak food off the kitchen counter or leave you “presents” on the brand new living room rug.

Dogs love humans—and it turns out, that bond can actually help us to train dog robots, too.
