Re: Implementing Traction Control for an advantage in the 2009 game

First, I want to thank everyone for such a wonderful open flow of information on this topic. This is such a tremendous paradigm shift from previous years that teams could fall into a "Cold War" mentality and not share this information with others.

Now, Paul Coplioi's post on the second page made one assumption that I thought I would try to correct.

I don't think that the mass cancels out in the equation for maximum acceleration (amax=g*CoF). If you walk through it carefully, you will see that while the friction force is Cof*robot weight, the mass that you are acceleating includes the trailer weight. In that case, the maximum acceleration of the system will be limited to roughly 75% of g*CoF.

This should only affect teams who are measuring acceleration. Teams using encoders and follower wheels (thank you FIRST GDC for the rapid response to that question) should not see a problem.
