This “follow-me golf caddy” known as The Shadow Caddy, has the ability to trail you around the course without the use of any form of remote control, making it a civilized compromise between dragging or carrying a set of clubs or foregoing the benefits of a pleasant stroll entirely by riding in a golf cart. It’s also cheaper than hiring a human caddy and because it is autonomous, it leaves your mind free to concentrate on connecting with that little white ball. The device works via a transmitter worn on the body of the user and uses multiple on-board CPUs and a collision detection system to navigate the fairways. [ShadowCaddy]
