Dogs love playing with balls but someone has to launch them. The iFetch takes care of that for you. It can shoot a small tennis ball between 10 and 30 feet. It runs on battery but can be plugged into an outlet. It teaches your dog to fetch and return. The device turns itself on when a ball is dropped in and shuts off when the ball is launched. Pretty fun to have if you have a dog.
This exciting project is being funded on Kickstarter.
