in the off season we experiment with different drive train and other ways to improve our robot for the off-season events so let me know what you think

Re: VIDEO: team 1528 drive train experiment
 

What kind of drive is that? Looks cool.

Re: VIDEO: team 1528 drive train experiment
 

Looks neat! I take that it is 4 omnis with one perpendicular in the middle making it a 5 wheel robot or is it some other configuration?

Re: VIDEO: team 1528 drive train experiment
 

I love the maneuverability. Could you give some more details on the drive train please?

Re: VIDEO: team 1528 drive train experiment
 

I can't see anything, well, I think that there is a more efficient one out there some where

Re: VIDEO: team 1528 drive train experiment
 

it looks like a 6 wheel omni drive, basically a tank drive with omni wheels, then 2 other omni wheels facing the other direction on the ends, looks neat.

Re: VIDEO: team 1528 drive train experiment
 

That's what I think too

Re: VIDEO: team 1528 drive train experiment
 

yes it is a six wheel drive
4 wheel tank drive (onmis) run by andymark supershifters
2 onmis perpindicual to the tank drive run by a cim motor in a banebot end
the straight forward and back were runnign a little slow but is now fixed to where it runs faster then it did in the video

Cool concept!

A few tips. When running omnis, you really won't need shifters. Since pushing is mostly a futile effort, it would save some weight to "downgrade" to Toughboxes. You can still go plenty fast with only one gear ratio.

I love how easy it looks to make sliding drivetrains do cool maneuvers like that. It seems so agile...

This "concept" is actually one that is has taken on a lot of use in VEX Robotics. In fact, this year we had two teams run this concept, and teams 148/217 also used this in their nona drive.

Nice implementation. Probably one of the more efficient multi-directional systems. But once again, you're not going to be putting up much of a struggle when it comes to defense.

Re: VIDEO: team 1528 drive train experiment
 

what exactly is nona-drive? I've heard a lot about it

Re: VIDEO: team 1528 drive train experiment
 

Same can be said about mecanum drives, yet people seem to love putting those on their robots...

Re: VIDEO: team 1528 drive train experiment
 

Nona-drive is a 9 wheeled robot 5 omni wheels 4 "treaded" wheels. There is an omni wheel in the center of the robot that runs perpendicular with the rest of the wheels, then at each of the corners there is a "pivoting system" that lifts the treaded wheels off the ground so the omni wheel in the center of the robot will then be able to drive the robot on its axis.

Thats my basic shake down about the concept.

The key advantage for us with the mecanum wheels was the speed and manuverability. I did not notice us being pushed around much but it could be that our drivers avoided the pushing matches. I did see that we were consistantly able to get to balls quicker than most and move them into the offensive zone or score.

exactly why i put this drive train together i wanted a high manueverable robot and put the super shifters on there for some control in low gear with steering but still have the option to get where i need to in a hurry
