Well, since Bob (our robot last year) has been lightened up a bit (read: largely taken apart), I got some nice pictures of our window motor drivetrain.
Your eyes are not deceiving you–window motor drivetrain.

looks cool… do you have any closeup picture of the drivetrain or just the drivetrain itself… if i could just see the drive train itself, i would probably gain some more knowledge about it… thanks… 
I’ll try to get some better shots with a decent camera next week.
Hopefully I can catch them before we start disassembling Bob.
how do you match a window motor to the drivetrain?
Sorry to contribute to reviving old threads but I haven’t seen this before. It is quite interesting. The good thing about it is that I bet it is very controllable and can run all day on a single battery charge.
Alright, I’ll revive it once more.
I FINALLY got some clear, nice pictures of the robot with a real camera.
Enjoy:

That is awesome (and crazy!)! When I first read about this I figured you were full of it, but now that I see it I gotta say I am really impressed :ahh: . What is the reduction with those sprockets, and how fast can you go?
Reduction? I dunno. (marks down on to-do list)
As for speed, we’re talking slightly faster than walking. There’s video at

But there’s already a discussion at http://www.chiefdelphi.com/forums/showthread.php?t=30761&highlight=window+motor+drivetrain, so I figure it might be the spot to go to.
You will be pushed around on the field and will have almost no toruqe, not to rag on you but last year I made a claw with the window motors and I could stop it with my hand.
My only question is why go with window motors when there are much stronger motors available? Is it just to be different…? You hit the nail on the head if that’s the case :]
Oh yeahn, I wrote down somewhere to watch that movie. I think you posted it while I was incredibly close to going over my bandwidth limit. Now I will stop talking about it and go watch it.
Thanks!
wow, window motors for the drive train, that’s pretty uncommon… what inspried you to go about that?
Thats from that thread Billfred linked to above.

Fortunately, this appears to have been last year. Besides, 2 Nippon-Denso motors would be illegal this year.
Believe me, we weren’t pushed around on the field. And don’t forget that a good driver will win over a good robot any day of the week. (This was the case in at least one match of ours.) And Bob had a few distinct advantages, namely that of low current draw (we only had the two window motors and a van door being operated) and being built like a brick. I still say it’s a good robot. With a proper arm, it’d be a great robot.
As for why, Ryan, call it rookie desperation. It was week four or five or something like that, and we needed some motors we could mount up and go with. (Like in the original post, we tried the others with only limited success.) Maybe we should’ve made a bigger to-do at Palmetto, but ah well. It sure was a blast.
The answers (and the discussion) are all here:

Erm, moderators…could y’all lock this thread, please?
So using just 2 motors and not much else for your driver train, what’s your base weight looking like?
Well, there were two more levels above it. There’s pictures somewhere on www.d5robotics.com if you’re interested. (And just a hint of information on Ockham and Hockham, our robot and practice robot for this year.)
Nevertheless, we made weight. No swiss cheese required.
