Vex Mecanum robot
 

Its finished and it works! After re-doing the wheels so the rollers are consistant and only +/- about 5* and adding suspension to the robot, the vex mecanum drive finaly works! Go here to see a picture of it or go here to download a movie.

Questions, comments, advice appreciated.

Wow, that's just... (speechless) It works so well! There is no deviation when it goes left or right, no problems forward or reverse, no trouble spinning in place at all. Plus the ingeniously simple solution for suspension. I didn't really think anyone would be as successful as you have been with a VEX Mecanum robot, but now I have been certainly impressed! Truly amazing!!! :D :D :D

Been a while since I awarded one, but...

Very nice design, now your putting ideas in my head :D

Re: Vex Mecanum robot
 

And that is not a good thing!!! :D

But back to the thread. Very nice design... I'd be interested to find out how you programmed that on the controller... I'm assuming a joystick going side to side, but I'd be interested to see how you wrote it out.

Nice job!

Kevin "borrowed" the code, it was posted on a holonomic thread,

one stick moves forward/back and side-side (and diagonally) for translation motion, and the other moves left/right to rotate, both can be moved at the same time.

That's a sweet robot, and I love those mecanum wheels. Nicely done.

Keep up the good work. :)


I see my code has been getting a lot of mileage lately. ;)
