No. A thousand time no.

Most of our wins are on Mecanum wheels so I like using them when they are right for the game. I agree with Ed - they are not a good fit for this game.

Re: Mecanum Wheels

IMHO, not enough traction to cross many of the defenses

Re: Mecanum Wheels

The disadvantage is that you have to cross polycarbonate surfaces in the barriers, you're gonna be sliding like you're ice skating.

However if your team is not planning on crossing barriers they lose their disadvantages

Re: Mecanum Wheels

I'm quite fond of mecanum wheels in general, but not for drivetrain in this game. They're not going to cope well with the majority of the defenses, and they're not going to have good traction on the batten.

Re: Mecanum Wheels

Even if traction was great, bent or broken rollers and/or support tabs will make you cry.

Re: Mecanum Wheels

On the majority of the obstacles, mecanum wheels would pretty severely limit your ability to cross. I don't see them being effective in this game.

Re: Mecanum Wheels

Please stop with the "mecanum wheels have no traction" stuff. They have plenty of forward traction.

I do not believe they are a good choice for this years game for many reasons.

Will I put my AM HD 6" wheels on a test robot and try and tackle defenses for the fun of it, heck yes!

Re: Mecanum Wheels

2052 found that in 2012 mecanum wheels actually helped on the ramps- they self corrected to get us on the ramps more squarely. The idea that they simply make your robot slide around like you just hit a banana in Mario Kart is simply a myth.

That being said, we have not yet discussed drive trains this year. I wouldn't be surprised if we went a different direction this year based on our requirements for our robot.

Re: Mecanum Wheels

I think the biggest problems are the robustness of anything but andymark HDs, and the fact that a lot of the defenses are going to be more manageable with more wheels. 6 or 8 wheel mecanum would be weird. On 6 i guess you could use omnis for the middle, and 8 would be omnis or another pair of mecanum. On any of those, things will get funky when you start losing points of contact, though.

Re: Mecanum Wheels

We love mecanums too, but this year some of the defenses would be hard to cross with only 4 wheels. I admit we have not tried them on polycarbonate, so the perceived lack of traction may indeed be a myth.
