WOW!!!:D :D :D Engine turned finish, full welded frame, anodized custom wheels, custom shifting transmissions...

Can I get a close up of those wheels? :)


(P.S. Please post more pictures!)

Re: pic: Team 195 driving base 2007
 

:ahh: Are those transmission plates delrin???

If so, that seems to have become a popular choice this year - Suddenly I feel left out with my plain old custom aluminum transmission plates ...

BTW - those wheels really came out nice with some anodizing! I'm still anxiously awaiting what ours will look like (they are going in tomorrow, hopefully)

What, no tank treads??

This plain looks awesome. Seems sort of reminiscent of West Coast Drive, with some requisite east-coast tweaks.

But what I'm really loving is how the CIMs are mounted on the transmissions. We're running the AndyMark two-speeds this season, and fitting them in with everything else has been a little hard at times. (Don't get me wrong, I still think we made the right choice for our situation--it's all part of the challenge.) Should the time come for us to start rolling our own transmissions, this is a picture I'm coming back to.

Hope to see this one in Atlanta!

Kudos on the custom wheels and delrin plates very nice. West coast style drive is always a winner I like the modifications to it though you guys have made. 1251 has a similiar drive base this year. Ohh ya the finish on that box tube is sweet,neat touch. Looks like a battle ready base see you guys in Atlanta hopefully.

I think they are also taken on a new look this year. Nice rims I like the blue

Re: pic: Team 195 driving base 2007
 

believe it or not the delrin is only in the temp chain tensioners...
all the black is simply ABS plastic

P.S.
the swirl finish looks really pretty black ;-)

Meh, I never did like the efficiency of those crash shifters.

Either way, you guys are gonna rock this year. This base looks good, and a practice bot/full playing field doesnt hurt!

(Any other college mentors feel like they got the short end of the stick when they left?)

Re: pic: Team 195 driving base 2007
 

wow 6 wheels? how do you turn?

Re: pic: Team 195 driving base 2007
 

cant wait to see this at the scrimmage !!!



tom...you were holding them back...hahaha jk guys

Re: pic: Team 195 driving base 2007
 

You lower the middle wheel by a small amount (usually 1/8" to 1/4") so that at any given time your wheelbase is small for easy turning, but you have the stability of a longer wheelbase. Only 4 wheels can contact the ground at any given time (unless you have VERY soft carpet)

Re: pic: Team 195 driving base 2007
 

Yes and thats why i came back =P...

looks great guys cant wait to see you at UTC *ill be scouting all of you for nats!!!*

Re: pic: Team 195 driving base 2007
 

Y lower the middle wheel. Makes no sence. :confused:

Re: pic: Team 195 driving base 2007
 

With any 4 wheel tank-drive wheelbase, long and narrow is much better at going straight, short and wide is better for turning. The problem with the short and wide is that it's easy to tip over in the forward and backwards because of the short wheelbase. The remedy is to take your long and narrow base and put a middle set of wheels that is lower than the rest. This gives you essentially two sets of "short n' wide" wheelbases that you rock between. This makes you hard to tip, but also makes it much more efficient to turn, and gets rid of the characteristic "hop" that many high-traction, 4wd robots have.

another version of the 6wd solution is to keep all the wheels on the same level and replace one or both of the outboard sets with omnis (see 488's robot this year)
