Re: Video of Mecanum Drive Running Circles Around 6 Wheel Drives

A MASSIVE problem with mecanum drive this year, just as you could have had the issue in Breakaway last year with our mecanum bot, is the steel plates under the carpet.

Our build lead and I ran some simple vector addition, and realized that any mecanum wheel on a slight incline like the steel plates under the towers can and likely will cause 20% of the force lost on one wheel diagonally opposite to one on the incline, and transferred to the wheel on the incline. This will cause you to lose significant control of the robot, and in this case, a trip to your scoring lane can likely end up as a trip to the opponent's zone. It is very hard to right the bot after that, and can cause the rollers on the mecanum wheel to lock up.

Be wary of this.
