Sure, while a lot of robots in development are designed to do important tasks that will help humanity, that's boring. What about the more mundane, the more frivolous, and the more ridiculous tasks that we want performed? Don't worry; there are robots for those too.
Just look at the Putter Bot R/C Golfer. It's a putting robot! It wheels its way over to your ball, lines up the shot, and hits it with the perfect amount of power. It's the perfect thing to bring with you to minigolf next time you go if you just want to take all of the fun out of it. I mean, it's remote controlled, so I guess it could be argued that you're still technically playing, but come on. It's a putting robot.
