Re: Team 2980 2013 Open Source Robot
So I am going to post some things to consider since I really don't want this thing to fail to an unrecoverable point. Here are some questions / suggestions:

1. Are you depending upon the actual weight of the robot to generate the normal force required for the wheels to drive up? If so, please realize that you will need a coefficient of friction greater than 1.732 (tan (60)) to get enough traction no matter what your weight.

2. If not, then your coefficient of friction + other method has to generate an effective coefficient of friction of 1.732 or this will not work.

The above is THE limiting factor for this type of design. I have analyzed this to the nth degree and it is a undeniable fact that you must figure out the traction problem before proceeding down this road. These poles are slippery, really slippery.

I hope it works ...

Paul
