The “follow-me golf caddy” also known as The Shadow Caddy, has a thing for old rich dudes on the Golf course. It follows them around without the use of any form of remote control, so they don’t have to drag their clubs around when not in a golf cart.
It’s cheaper than hiring a human caddy and leaves them free to concentrate on the ball. The device works by using a transmitter worn on the body of the user and uses multiple on-board CPUs and a collision detection system to navigate the fairways. It won’t improve the Golf game of old rich dudes, just like it won’t improve their fashion sense, but it will make them feel important.
