That equation doen not seem accurate

You put the weight down..not the force pushing down

Te acutal force on the casters is as follows

181 pounds = 82.1 Kilograms

so 82.1*9.8m/s^2 = 804.58 Newtons of force total

Now... to find the coefficient of friction...

Friction = Mu*Mass*Gravity
or in this case ----> Mu(804.58)

so in order to move this goal...

You plug in the following

Force of Robots Push or Pull - MU(804.58) = 82.1* Acceleration

Now...to fin dthe minmum force needed to move the goal...

You set acceleration to zero...

So you get... Force of Robots Push or Pull - Mu(804.68) = 0

Force of Ropbots Push or Pull = Mu(804.68)

Force of Robots Push or Pull / 804.68 = MU

There you go...just plug in the force from your robot and you should find mu.

I need to check some notes..but there might be a better way...

And remember Its in Metric
