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
