Keys to Success:
Make it reasonable. One year, we had a group build a "Magic Carpet" which entails some machining and software. Also, we used mecanums, which we had to purchase. To top it off, we added a special controls system that utilized an Ipod to control it.
Benefits are extremely numerous. Awesome sponsor talking point, Money Maker (kids love it, let them ride it and at your booth/stand have a little donation box... champs here we go). Kids enjoy the fact that they did it and can talk about it FINALLY!
Is there any way we can get a picture of the magic carpet. sounds pretty cool
