    Re: Direct drive wheel configuration

    We used a similar direct-drive Mecanum drive last year. The plastic plate on the Toughbox can be cracked, you might been to fabricate a metal replacement. You also might want to consider that a stiff suspension like this can cause a wheel to be lifted as the robot traverses the numerous bumps under the field carpet. The mecanum drive vectors are very difficult to understand with only 3 wheels in contact. You would want to practice on a surface with bumps.

    Direct drive wheel configuration

    We are considering building a direct drive config similar to this one by andymark

    http://www.andymark.com/ProductDetai...ctCode=am-0485

    These would be using the tough boxes from last year and 6" mecanum wheels.

    and for the gear boxes we would need to buy theses

    I was wondering if this configuration could support the weight of the robot. It would be putting a lot of strain on the tough boxes.

    And would the gear ratio be too high? 12.75:1 with 6" mecanum wheels?
    what could happen if our robot is geared too high?
