Re: Mecanum
Andy, I like your idea of having variable preload on your rollers. Have you done any actual "bolt torque vs. traction" tests with these wheels?
Also, I read through the assembly instructions for your wheels, which is very helpful. However, I've found that one student's idea of "finger tight" varies greatly, so much that finger tight can mean finger loose, or opps... I stripped all the treads. Do you have any more specific guidelines for the bolt torque?
As a comment to rookie teams, the AM wheels and kit gearboxes and chassis can allow you to quickly build up this system mechanically. However, purchasing two extra gearboxes and the set of wheels is a pretty good chunk of change. Also, I believe the programming and feedback required for this system is also a challenge. I certainly encourage all teams to improve upon their previous designs and challenge themselves. But please, try to understand the limitations of your team, and the resources that you have.
And, as a side note, GUS will be entering its 9th year in FIRST this season. With all the experience we've had, and iterations we've gone through, we've still been beaten by our fair share of rookies using the basic kitbot.
