We've just had a new "FabLab" open up in Coventry, and I've been in talks with the owners to run an antweight building class one day over the summer. The intent would be that people pay a fee, build a robot during the day, have a small competition with them at the end of the day, and then get to keep everything at the end.
I'm looking for suggestions for components for this. My main goal is to keep the price as low as possible, which isn't something I'm historically good at, as I tend to spend far more money than I need to!
My thoughts so far are thus;
TX: Blade or similar
RX: Whatever is cheapest on eBay; lemons/oranges?
ESC: Maybe a bulk discount deal on Roryboards

Batteries: The cheapest option would probably just be some standard AA or 9v batteries, but I'm concerned about the weight. I guess we could use these during the class, with an increased weight limit, but provide links for LiPo information and stuff for those who wanted their machines to be competition legal after the class?
Motors: Cheapy eBay gearmotors, I was thinking a couple of different ratios, provided with a couple of different sized wheels, to give people options.
Wheels: As above, a few different sizes. Would see if there's anything that's cheap in bulk from Pololu, or could look at printing them.
Servos (for weapons): Whatever is cheap and a reasonable spec, need to spend some time researching for this.
I'd appreciate any suggestions or advice, especially if anyone has done something like this before!
Thanks,
Scott
