Re: Poll:2010 How many wheel drive are you using?
 

You could do like your delphi team of '07 did with 14 wheel drive.

Re: Poll:2010 How many wheel drive are you using?
 

Team 45 came up with a One Ball drive system a few years ago. Does that count?

Re: Poll:2010 How many wheel drive are you using?
 

816 is going with an 8wd this year.

It should work pretty well for us - as long as our driver remembers that getting air crossing the bump is a bad thing...

Re: Poll:2010 How many wheel drive are you using?
 

Wasn't it two balls? (The robot was 2003's Mighty Mouse, which was ultimately not entered by 45, in favour of their other 2003 robot, Mighty Auk, which used more conventional treads. Mighty Mouse did see use by another team as a result of some extenuating circumstances.)

Re: Poll:2010 How many wheel drive are you using?
 

I agree, except in this case I think less is more.

We are going with 4 wheels this year after a demonstration showing the dynamics is much more stable than 8 wheels could ever achieve.

Most 8 wheel drives are counting on very low center of gravity, except I don't think you can count on that if you want to do any sort of hanging, or if the CG is anywhere near 10-12 inches off the ground.

Sounds like a swerve to me...

Team 2395 is doing 8wd this year.

Re: Poll:2010 How many wheel drive are you using?
 

i suppose you could say that we're going with 12 wd... all will be powered... and all will stay in contact with the ground all of the time, and that's all i'll say. :p

Re: Poll:2010 How many wheel drive are you using?
 

Tank drive me guessing?

4wd for us.

Re: Poll:2010 How many wheel drive are you using?
 

Hey Ken,

Long time, no see (though more my fault than yours).

But... ...there you go again making blanket statements that may come back to haunt you.

Of course it is possible to make an 8WD or even a 12WD that is less stable than a 4WD robot going over the bump, I would just caution you about making statements that beg to be proven wrong.

"There are no black swans" only requires 1 observation to be wrong. "Black swans are rare" is a safer statement that is less likely to put egg on the face of the speaker.

Team 148's robot will have 14 wheels in the drivetrain.

Seriously.

Re: Poll:2010 How many wheel drive are you using?
 

I love blanket statements! It's probably going to come back to haunt me, but what I mean is all the flat 8 wheel drive I've seen is much less stable than the 4 wheel drive chassis I have in mind. Of course it's possible to make a 8 and 12 WD base stable when going over the bump, but that's beyond all the flat 8 WD I've seen (rocker bogey comes to mind, as well as other pivoted or pneumatically actuated chassis).

I was so sure of my gut feelings that I convinced my team to choose 4 over 8. I convinced them there is going to be a lot of fights around the bump, and sticking half your base out is probably not the best way to become the king of the hill.

I think this is going to come back to haunt me, but I tend to live dangerously these days...

Besides, I only chose the simple 4 WD because it is well within our manufacturing capabilities to produce. I would love to go crazy, but that will have to be another year in another game when I've gotten used to working with this team...


I am starting to be really scared of all the drive train that haven't been posted. Seriously.

Re: Poll:2010 How many wheel drive are you using?
 

a 1 wheeled robot would be epic

Re: Poll:2010 How many wheel drive are you using?
 

176 will be going with a *modified* 6 wheel drive this year. ;)

Re: Poll:2010 How many wheel drive are you using?
 

we are going with eight wheel im going to be posting videos soon but we have so much power that we were able to drag a 115lbs man

Re: Poll:2010 How many wheel drive are you using?
 

With all those wheels teams are using, I see them having a problem making weight.
