Re: Code For Mecanum Wheels

Having had a mecanum drive the last two years, we have attempted a number of control algorithms and have settled on this one. Please note that this algorithm takes advantage of Binary-Radians (256 b-rads per revolution) to simplify the trig math.

I hope that you find this useful in your attempts to control your onmi bot.
This seems really complicated. We've found that the method I linked to above works just fine and is quite easy to program.
