thursday. 33 days.

if we're judging strictly by physical progress, today was not a productive day (although i dont actually know what's going on with that chassis). general design and administrative stuff is going well though.

i know that those gear boxes and transmission stuff has been keeping build/anndini/allie/crystal very busy. "the shuttle" of me, anne, and allie had to leave by 7:15 to get anne on that train, so i have no clue whether more progress was made on the chassis, or if we could drive by the end of the evening.

driving that prototype chassis has been our nightly goal basically this entire week. i'm really seriously hoping that it WILL happen tomorrow. i know electronics needs to basically feed the brain (remembering that we are using an OLD RC and accomodating for its withered brains) in order to get it actually functioning.

i'm really wanting to mess around with drive code this weekend (can't be at LEAST get scotty up and running? is his poor chain that badly off?) and see whether the window filtering, etc that we learnt about wednesday actually sunk into our brains. it sounds like it would smooth out so many of those problems from last year.

after multiple pro-con lists and design meetings and prototypes, i think we're 90% sure we want to go for a threeprong claw on some sort of lift. how to actually make this feasible while fitting within the topless 80in cylinder AND not tipping over because of our center of gravity? i have no idea. jesse and karlin were chatting about that with us.

reasons for eliminating other ideas: windmill idea, while incredibly cool is HUGE, fairly complex and would require a lot of torque and precision. a lot of people were really committed to hurdling, so a three prong without a lift would not allow that. with a lift, if it fails, hopefully the claw will be functional and we can just be a low, speedy bot.

the three prong claw has a, uh, rather ghetto prototype made out of pvc (hello, i love you) and duct tape.

(lack-of-an)update on the mecanum wheels: they have not been shipped yet, so really, i have no clue when they'll be arriving. there were no shipping.

generally, that was the gist of things.
maybe i can blackmail anne/crystal/nandini/someone into posting about the nuts and bolts (literally, i suppose) of the chassis progress.

shouldn't we start making BoMs and dimensions and ordering (after getting jimmy's permission, of course ;P) parts and stuff for the chassis, if not the robot in general? that way, when we finally actually want to build something we'll be able to? i dont know what protocol for this is.

anyway. those are my random thoughts of the night.
see all tomorrow!

again, weekend hours of 11-5. 4-7:30ish tmrw.
