Too heavy
I represent team 66. We build the sturdiest drive chassies i've ever seen, and can rarely be beaten. It is a little know fact that our robot for this last year was actually meant to handle balls. we only had one problem, a 95 lb drive chassy. We are big fans of the 1" extrusion but in my pit scouting for the last few years i have noticed something, The robots built for first don;t have enough power to bend 1" extrusion with any kind of blow.
I beleive that 20 mm extrusion, very light by comparison to its big brothers, has more than enough strength for our purposes. As for polymers in construction, i haven;t seen many good examples of structural framing comming from it but have seen it in many good low impact uses (33's ball carrier a prime example. But after seeing the plastic bot of, i believe, 49 fall over at grand rapids last year and loose its arm, i have been weary of plastics use for robots. |
