Wouldn't there be balance issues with a drive configuration like this?
Certainly an interesting concept regardless; at the very least in certainly makes good use of space.

I didn't see any issues. At least not in terms of tipping.

Wait, can it strafe? How do the wheels look while driving?

It can strafe. Can't say I was paying attention to the wheels. Talking to the team, they started with mecanum code.

What’s the main body piece made of? It’s not fiberglass, is it?

Right the first time. You should see their regular-season robot.

Is that back omni wheel powered? It is hard to tell from the picture, but would make most sense if it was powered.

All wheels are powered.

Some of the chain runs actually drive the lift.

I LIKE IT!

Seems like the U-drive concept is popping up all over this off-season (third I've seen posted, including my own), but this one definitely takes it to a new level, especially when it comes to controlling unintended torque, and also in wrapping around the game piece.

Are those chains or belts running to the back? Are the motors all the way back with the strafe wheel? That looks like too much slack.

I'm trying to understand the overall benefit of this configuration vs a standard mecanum setup or even front mecanum back 2 omni. Surely this config is not favorable in traction with only minimal benefit to powered rotation. Weight reduction (3 gearboxes vs 4)?

Chains. Not all of them are for drive. I forget exactly where the team put their other drive motors--the outer ones look like the lift chains. (Of note: the midships gearboxes change chain direction to operate a lift, and are not part of the drivetrain. Unfortunately, they didn't quite have the time to get that fully operational.)


Edit: Just for the record, I'm not affiliated with the team. But after seeing that... Well, here's the result. I'll have to see if I can signal one or two of the 585 folks to describe it in more detail. As I said in the description, I've never seen a drive like this before.

Got pictures for those of us on the other coast?


You can't make a statement like that and not provide a picture.
