Mecanum Drive

[yclee31]

So I'm planning on using the mecanum drive system for next year.
and just to get a head start, i want to start coding now.
so what is a basic structure for omni-system drive?
if you guys give me some helpful advice and pseudo code
and also some help on correcting human errors and all
i will be thankful haha

Come talk to me during snack.

You guys gets snack time? Time to start that on my team.

Why in the world are you planning on using one type of a drive system for next year?

There are teams that will laugh at Mecanum regardless of the game. Some pull it off with the right implementation, but I don't think you should say you're planning on using Mecanum for next year.

If it's for educational purposes, sure, we'll help you out...

I'm not just saying, just sayin'

He just wants to do it for educational purposes from what I can see. There was no actual decision made. We were considering experimenting with several different drive systems. Swerve being one of them. I don't know why he has not come up and asked me for help... -__-;; But I will talk to him tomorrow.

By the way, he has no power what so ever to make such drastic decisions. Even I do not have such powers. I can convince, but not mandate what drive we should use.

I wish we got snack time... it should be right after the nap time I wish we got.

Ignoring the last sentence... THIS! Saying that would be like saying "I'm going to use an elevator." You COULD do it but it may not be the best option.

Now, having it in your bag of tricks is nice so for an off season project? Go For It!

What do you mean by the last sentence?

i dont have any knowledge on coding omni system drive so i was asking for help
we did not decide anything on next years drive and my team's adviser allowed me to play with some drives so i was just asking
i guess my word choice was bad

Or use the provided mecanum drive in the WPI Library.

Have mecanum wheels ever touched Einstein?

I think it was 294 last year who had mecanum wheels on Einstein.

Are team has used mecanum for the last 2 years, never again. Look in to swerve if anything but as an off season project GO for it!!! it will be a fun programming challenge plus there reallllyyyyyy fun to drive up and down the hall ways (we take our 2011 robot out and do figure-8's during lunch)

Sorry to tell you, but 294 used our favorite 6 wheel drop-center shifter drive-train last year (this year as well). To my knowledge we have never done any strange kind of drive-train, though we did do a weird semi-holonomic system for Lunacy

As far as I know mecanum has never shown up on Einstein, but I could very well be wrong

its actually relatively simple, assuming u know trig
Essentially what need to be done is get the direction based upon a 180 degree circle, find the vectors, multiply it by the magnitude of the joystick, and then finally adding or subtracting the rotation

It's simpler than you think. Mecanum requires no trigonometry.
