John, (or anyone else who has followed the math of this approach)

I found this link

Can this same ramp technique -using testing material (e.g. carpet) on ramp- work to determine the static CoF for wheel traction by simply locking down the gears (i.e. make them never move during this test)? Or is there an easier way. I know wheels are rated, but it would be nice to actually measure it.

p.s. I presume robot must have a low CoG for this test so it will not tip over.
