Nice idea, but…
I thought the rules for bringing a challenge said that you had to be able to prove it could be done yourself. I have been sifting through all of the robots here for a while and while some meet a few of the criteria, perhaps the challenge is either too ambitious, or perhaps a few too many steps ahead. I mean, that cool Giger robot cost the guy a pretty penny to make, and it wasn’t five feet tall. I would echo Oddbot’s statement about the first prize having to be kinda extravagant.
Points for enthusiasm, but maybe something a little more realistic.
