Here’s what they need to build: A dog robot. When people are out walking their dog, you can tell why they have that dog. The cute fluffy ones are usually pretty friendly, the pitbulls usually are not. But even the friendliest golden retreiver will defend its master’s safety with ferocity.
A robot could just walk behind you, if you’re ever in any trouble it comes to your assistance. It could call 911, video the event, fight off attackers, administer first aid, all kinds of stuff.
I would like a robot dog. I’d buy one if I could afford it.
