Not a suspension.

What's going on in those wheels? Looks like a lot of linkages.

[Cuog]

Looks like a psuedo suspension. The wheels look to be able to tilt up/down which would help a little in covering uneven terrain. One problem is that the pivot for the suspension is in a different plane than the U-Joint so there would be a tendency to try and stretch the U Joint unless it has something like a slip-yoke.

[Marc S.]

Looks like a possible crab module, with 2 wheels spread apart for stability, a differential in the center for better turning and U-joints for smooth suspension. Maybe next years surface will be very bumpy.

Looks like the robot version of an automotive Independent Rear Suspension (IRS).

That's a really neat project to do when you're bored! nice

I think a rough terrain game is inevitable... and would be very cool. There seems to be a lot of teams that perfect their preferred drive train in the off season and spend the time during build season focusing on game play. Making a bumpy playing field could help, er, level the playing field for newer teams... like mine!

Okay, I'm going to try and describe this. It's a swerve module with a differential connecting both wheels, and flex couplings to allow for some sort of suspension.

I can't possibly imagine its use in FRC.

Coaxial swerve modules with a suspension and differential aren't normal. But on Winnovation they are.

Winnovation: Not even once.

I can't figure out why you have four Bevel gears (forming a box, differential?) connected to the left wheel... couldn't you achieve the same by extending the shaft from the right wheel directly to drive the left wheel?

THANKS!

Actually the box results in the two turning in opposite directions.

[MrForbes]

The differential is used in the drive axle of cars, read about it

RIGHT, but you wouldn't want them to turn oppositely, correct?

This has me scratching-my-head... ;-)

[EricH]

Actually, Michael, lemiant didn't have a chance to read squirrel's link yet. I would suggest reading that link, then figuring out the drive system.

Short version: If both can go the same way at the same speed, both go the same way at the same speed. But if one of them can't keep that speed up, then it doesn't have to due to the way the differential is set up.

Here's an animation of how a differential operates for those confused.

[MrForbes]

Here's a much better explanation.....but then, I do like old stuff
