This is a fantastic idea! Team 1515 would love to contribute!
I can send you a .zip of all LA Regional robots.
These came from our scouting data this year. We never actually used the images, but I have them on my computer regardless.
If this ever does happen, please email me at
msimon@msedesign.net
I may be able to get ahold of pictures of the robots from the Israel (IL) Regional, so if I do so, I will post again.
