As an ex-golfer and gadget/robot freak I have to admit this is rather a cool idea. The Shadow Caddy is a sort of “robotic” vehicle that you put your golf clubs on and it follows you around the golf course.
I’m not sure how good it is and how well it copes with the often rough terrain of golf courses, in particular if you’re like me and spend most of your time in the rough on the course. The upside is that you don’t have to drag a cart around or carry a bag and you won’t have to listen to snide remarks from your wife caddy when you hit a bad shot, the downside is that you don’t get the info and insight of a good local caddy about club selection etc and its not capable of helping you find your ball when you hit it in the really thick stuff.
