I got bored so I went to
http://firstrobotics.net/03gallery/ and counted the bots best I could just looking at the thumbnails, except for the really cool ones. Out of 147 bots heres what I saw.
17 Low/Scissor Stackers, the names pretty clear.
18 Bin-Huggin-Hippies, these gals hold stacks inside a structure of some sort.
9 ForkLifts, again clear.
8 Chlidren of 2001, with multisegment arms they are reminescent of the 2001 big-ball bots. Additional props to 513 for one of the biggest arms ever.
2 Camels, these cigarette smoking bots carry crates horizontally over there backs.
6 Ramp-Doms, secures the entire ramp.
There were many more bots that didn't have a clear category, and other bots that looked as if they were incomplete or just ran around pushing boxes.
