Re: Can Mecanum wheels pass the scoring zone?

I will second pfreivald here. It is easy to build a mecanum drive and easy to program with the already available resources. As with any drive train, uneven surfaces can be a problem, but that is one that you can solve by practicing. Having the bump lift wheels off the ground can largely be dealt with by wheel size and/or where the wheel is mounted. My biggest concern with mecanum this year is actually that it tends to produce a bumpier ride than standard wheels, which might present a stability problem, depending on your mechanism for picking up and carrying totes/containers. That said it is one of the drive train choices we are prototyping now.

Re: Can Mecanum wheels pass the scoring zone?

Uneven surfaces aren't even the problem people seem to think. Worst comes to worse, the mecanum drive makes a passable tank drive over most terrain.

Re: Can Mecanum wheels pass the scoring zone?

We ran mecanums for rebound rumble & ariel ascent. It handled the bridge & running over piles of Frisbees. As any drive train, it requires driver practice & a thorough understanding of its strengths & weaknesses. In you plan to use them in this game, you need a realistic scoring ramp to practice with.
