Check out 701s shifting tranny..

i'll release a Cad file some day but not yet however..... i guess you should look at the AM shifter they have cad files for that and it is definitely a more proven design.... i think the site is www.andymark.biz

i think we will soon begin fabrication of the tranny... any last minute comments LOL.... with our CNC mill we should be able to churn these transmissions out quickly enough.... maybe 1-2 hours a plate... the gears will be hard to do since they are stainless steel

Good luck with your transmission (both in design, and function). In the years that I've been doing this, I have always been involved with the "drive & chassis" in some way. Last year it was by building the transmission, and this year I did design a transmission (and a few variants of it). but a few weeks ago we stumbled across this nice 4 speed automatic, and I'm working up a prototype of that (it had 4 speeds, but I have an idea for adding a high low range). So, the driver can choose between normal range,and a lower range for some more pushing power. It would be similar to a tractor. Giving it in effect, 8 different gear ratio's. Stick with drive and chassis, and keep working on designs. Also, whenever you get the chance to do some of the machining, do it, it's a great thing to know. I myself have been the lead machinist student on the team, as said above last year I build the tranny's, and then I also designed, and built the winch. I go to school for mechanical engineering, but all my free time (what little I have) you can find me in the machine shops.

Good Luck, I look forward to seeing you design come to life.

I was thinking about shortening the plate so it doesn't block the back of the FP ... however since this transmission will be completely exposed... i don't want another robots appendage pulling out FP wires or whatever...
the transmission is going to be mounted between two pieces box and the wheels inline with the transmission (the sprocket is housed w/ in the transmission)
