Dude. Really?

Hi Mark. I am trying to educate the great people of CD proper mecanum spelling. If I don't, who will? I like to think of myself as the Batman for mecanum spelling.

I am kind of obsessive about (my own) spelling myself, so I sympathize with your quixotic quest, but you should probably be aware that people might not appreciate having their spelling corrected, especially if you're not making any other contribution to the discussion. If you're not careful it's easy to come across as mocking or derisive. When someone is trying to contribute to the discussion, and the reply they get is nothing but a correction of their spelling, that's got to be unpleasant.

What really matters is communication, and anything roughly of the form mec(h?)(a?)num is easily recognizable. The spelling is bizarre anyways. If it's important to you to get people to spell it correctly, my recommendation would be to write helpful or interesting responses to other posts, and add "FYI: 'mecanum' is the correct spelling" at the end.

The dude made up an account to correct spelling. Methinks it's a troll.

This is the first troll I've ever seen with a full rep bar.

I understand what you're saying. Thank you for the suggestions.

I can assure you I am not trolling.

Robotic geeks appreciate good spelling.

The spelling bugs a lot of people. here is Andy Baker's take on it

[pfreivald]

At Championships a few years ago someone cut me off mid-sentence to correct my pronunciation of mecanum....

I looked him in the eyes, dead-pan, and said, "I don't care."

He about lost his head under his little jesterly hat.

Looks like you're in luck. //end thread derailment

Has anyone done anything with using a gyro to correct mecanum issues? People have mentioned it in this thread but I couldn't find any examples online (all I found were examples of how to use gyros for field-oriented control, which is cool too). It seems like it would be fairly simple to, say, store the current gyro angle whenever you start going straight (i.e. not rotating), and have a PID controller change the "rotate" value to maintain the same angle as long as you're trying not to turn. Has anyone done anything like this?

I don't think "mecanum" even has a correct pronunciation; on our team we say me-CAN-um /məˈkæ.nəm/, but I think i've heard MEC-(a)-num /ˈmɛk.(ə.)nəm/, which presumably is where the "mecnum" spelling comes from.

The platforms are two inches high and the ramps are at 16 degrees, giving robots seven inches horizontally to move two vertically.

There's nothing in the manual about not driving over the scoring platforms. In fact, it makes sense that many robots would have to drive on them in order to deposit their payloads.
