Coefficient of Friction Testing

[JVN]

I just published a post which highlights my method for calculating the coefficient of friction for robotic drivetrain systems.

In my opinion... it is not sufficient to test the coefficient of friction of a single piece of tread, or a single wheel on carpet -- we need to test whole systems, and determine THEIR coefficient of friction. Only by testing the actual configuration of the robot you're going to use (i.e. the correct number of wheels, the correct tread contact size, the correct weight etc) will you get the correct coefficient of friction.

See full post here.

So this brings up my next question...
Who actually bothers to do this?

Does anyone? Is it just me?
Does your team have their own method?
Does your team just trust the manufacturer's specs?
Do you even care, or do you just say "this is grippy as heck" and not bother?

Please share.
