Thanks for the update.

I used 7400 for freewheel speed based on Richard's dynamometer results and then I adjusted the friction number until it approximately matches the video evidence of our minibot...
it predicts 2 lbs of friction!!

I'll try some experiments the week with a weight scale and the pole.

The other thing we might try is a time measurement of a distance measured freefall of the unbraked minibot on the pole as compare it to the speed of freefall without a pole and consider the difference to be the loss of acceleration due to friction. (I like pulling out my 400 fps camera).

I also started toying with the idea of tweaking your model to compare a rampbot to a vertical bot. I haven't got it quite figured out yet.
