Looks like both drill motors (with transmissions) and both CIMs. The CIMS are sorta tough to see, but they're there in the front of the bot.

WOW! That is one impressive drivetrain...good luck at comps!

Re: Unwanted Opinions
 

AH, I found that a bit rude towards my teammate. He was giving constructive criticism and a compliment to you. Your return was a hostile remark. Well, if you really wanna do that, maybe people in your team should spend less time with chain and read this so you don't clog up one page of posts with high res pics:

Ah yes, that IS on the announcement page and I pointed it out for Team 68 too. The gallery is there for a purpose. You can't argue with me on this.

Oh yeah, and we don't worry about our robot because we finished 5 days early; had time to do a demo for our favorite sponsor and also have around 30+ hours of driver practice (2 teams each).

Nice robot. You guys did a great job.

Also, the best way to deal with immature posts like the one above is to ignore them.

Good Work and that drive system very interesting

Team 998: Do you guys have any movies of this bot in action, i'd be very interested to see.

monsieurcoffee: I'm really impressed that you have read and memorized every rule and every post on chiefdelphi.com. My hat's off to you. The sad thing is that you two little webmasters are probably the people not actually allowed to touch the robot. So they sit you on the computer and tell you to watch this site. SAD! So why don't you just go color your hair and put on your black clothes and make yourself comfortable.

If you don't like my hi-res pictures then why don't you write an e-mail to the makers and tell them how I'm killing your bandwidth. Get them to move it.

Shoulda used cable not chain. You could've had tons of extra wieght to use, chain and sprockets are heavy.

I think we considered that, but there is an ungodly about of touque required to turn all 8 wheels. We use two globe motors for the job. We were using smaller chain but it kept breaking. So we had to up all the sprocket and chain sizes.

wow.. that is one cool bot...

are u any bit worried about a bin falling on that and knocking out any of those chains tho?

or is there something covering the whole bot?

There will be wires stung across the top of the bot. Hopfully that will keep the boxes out.

Theres no need to be so hostile people. There arent that many rules, most are common sense, there are only 3 or 4 others.

If you are talking about CD's webmasters, I pity your lack of knowlegde.

If you are talking about 639, if ya look, monsiercoffee is their driver. I highly doubt that he isnt allowed to touch the robot.

The rules about not posting a bunch of images in your post, but instead linking to them is so things load faster. Its not just some dumb rule, its to help everyone out.

As a general note to everyone: cant we all just comment on the good things about peoples robots? Theres no need to criticize them about their design. You don't want people telling you how bad your robot is designed do you?

The chain is sweet.

If you're underweight, chain weight shouldn't be a concern, to me. Criticizing you for using chain is about the same as criticizing you for not being able to stack 100 boxes; it's just plain silly. Be proud of your machine, it looks great to me.

For any doubters, it's worked in the past. Maybe not perfect, but a similar system was used by ChiefDelphi (chain for translation) in '99 and a very similar system was used by 190 (chain for translation and driven off bevel gears) in '00. I'm not a fan of chain for power transmission (we're all spur gears this year), but that's the best way to do a four wheel, mechanically linked swerve in my mind. Especially considering all the traction on those double wheels. Like I said, looks sweet. I hope I get a chance to see it in action sometime. Which competitions will you be at?

Frankly, I don't blame teams for being hostile with all the negative posts lately.
For the sake of your team, please try to keep a cool head, but the nitpicking is entirely out of hand.
You can only judge a robot so much from half-finished pictures and never seeing it actually move. Try not to let the negative comments get you down. Only you guys know the real capabilities of your machine. Last year we introduced the first holonomic drive used in a FIRST competition and half the comments we got were "your traction isn't any good". Well, we proved that wrong by winning an important defensive match (something our bot was never designed for) against a machine with seemingly better traction and power.

Good luck and I'd love to see video.

coffee.. he followed the rules. He doesn't HAVE to post them to the gallery. He referenced them with IMG tags. He's wasting (if you can call it that) his, or his team's, bandwidth not ChiefDelphi's. Apache is handling the requests, not SQL.

There's too much whining lately.. we need a hug forum

all i can say is wow....impressively complex drive system...kudos to you.
