It has a cylindrical shape with a wheel in the back like a tricycle. There is a camera so you can see what your dog is doing. A microphone and speaker let you talk to your dog and hear him, too. And Laika has what is bound to be your your dog's favorite feature: a treat launcher. > You can use an app to see and hear your dog at any time. You can even drive it around to play with your pup. Laika also has an autonomous mode. It uses a quarter-size tracker that attaches to your dog's collar to find and engage with your dog until you return.
