I would say that I now take part mainly for the social side of things, meeting people who I would otherwise never have even spoken to, but it was really the challenge that got me hooked in the first place. I love the fact that I have something to do, and that every problem with a robot means a new challenge to find a solution to. If I didn't do roboteering, I'd have a lot more money, but nowhere to channel my love of mechanical fiddling (I would probably revert to taking things apart to see how they work, and then not being able to put them back together).
