Dogs require exercise and play to stimulate them both mentally and physically, frequently through the game of “fetch”. However, physically disabled dog owners may lack the strength or endurance to play with their pets. We developed a prototype for an autonomous fetching entertainment center for dogs. We studied current products on the market and innovated upon their limitations. We developed a unique launching system that can be safely operated indoors or outdoors. The Fetching Interactive Dog Occupier, or F.I.D.O., can be used by a dog with or without a human operator. FIDO launches tennis balls at varying distances, and even offers positive reinforcement (treat dispensing) to train dogs in returning the ball back to the system and placing it in the hopper.
