this year i had a really good idea for build.... it was a hybred, but a little complicated, i built a model out of k'nex, and the kid who did the designing for 1694's bot shot it down...
i had the best k'nex machine for triple play and FF Raising the bar too, all built with knex, i also had one for Aim high.

note, this was just in the planning stages, i had this thing built by Saturday night of the kickoff.
