Ohh Well another trans down the tube

[matt111]

same kinda thing happened to us. we were just wrapping up our "continuosly varible torque, velocity, and steering transmission" and now we gotta pick up balls. i say next year we have a FIRST drag race

That is over kill, but try the technokats at www.technokats.org

3 motors? Be carefull there, don't wanna draw too much power at once, theres a whole set of problems that come along with that.

Also, speed and power are both important for this game. There's always a pushing match somewhere...

And speed, oh man, now thats gonna be a large factor...

Matt, that is an awesome design. Nice job.

I'm sure you know that not being able to realize the benefits of it this year is not much of a loss in the long run. You just added a great design to your "tech shelf".

Matt,
It's a beauty. Too bad you're not going to use it.

We're in a similar boat, having designed and built a full 6-motor, techno-knockoff drive this fall. Like you, we decided it would be better to have a powerful design if we need it, and maybe "tone it down" a little, than be in need and have to start from scratch.

Obviously, we don't have a need for THAT much output power in this game (*gasp* Did I just say that?), and we're deciding what functionality to "cut" for our 2004 system. So many numbers to plug, so little time!

I am curious how the servo handles shifting. Any troubles with it? Any regrets?

Tough luck missing out on 2004. Hope you'll be back in ohh-five.

That is one sick transmission. I know our team has always been trying to find some type of advanced transmission like that. I would really like it if you could send me some blueprints, or specs, or better yet put them in the white pages.

Any time or effort spent in which you learn new things and develope new skills

is never wasted

Good grief how much does that transmission weigh? like 40#? we built one using the CIM (or whatever it is again) we have a high speed low tourque and low speed high tourque. it uses the CIM, aorund 10 1/4 inch gears and a pneumatic cylinder somewhere around 3" long. it only weighed aroung 8 pounds or less?

Your third motor would have been better off on you end effector anyways.

Suprisingly light actually, the gears are all lightened, the crossmembers are aluminum alloy, the box itself is made of ballistic lexan 3/16". The Bosch mount is aluminum. The final version is see through and really nice looking. It would be tough to pack this much power in a much lighter package and still stay robust.

What was the final weight of each?
