Re: Help with drive train
Im going to chime in also...
Given im relativly new at designing geartrains, Ive been around FIRST for a while and i know what works and what doesnt.
SIMPLICITY
Being (as i assume) a sophmore team, you kind of get the idea that your rookie year you would see what works, what doesnt work, and what other people have done.
I like the Atwood motors. They are easy to mount, and you can mount it anywhere.
Go for a simple reduction. Estimate the FPS you want to acheive by figuring out what wheel diameter you want to use. then lets say you want a 6" wheel with a desired output FPS of around 8
*USE JVN'S SPREADSHEET*
Input your drill using a 14tooth 20dp.
From the 14tooth go into a 64tooth 20dp.
*thats just gearing*
then on your box's output shaft use a 10tooth #35 sprocket
to a 28tooth #35 sprocket on your wheels
THis would give you 9FPS
PM me if you would like a copy of this spreadsheet i used.
I would recommend using the skyway wheels that come in the kit. the 6" ones. and cut grooves in them for added traction.
and please if you have ANY questions, feel free to ask anyone of us who post here regularly for help...i have been helped my Andy and John. They aer very helpful for questions.
GOOD LUCK!
