Ok, here are my calculations:
Unknowns:
f=force
t=torque
r=wheel radius
p=power
Knowns:
m=max mass (it will lose weight as it runs due to liquid dispension)=45.359 kg
a=max acceleration=0.119 m/s^2
r=wheel radius=0.102 meters
s=max speed=1.341 m/s
f = m * a
f = 5.398
t = f * r
t = 0.551
p = t * s
p = 0.738 watts (assuming there is no friction in the wheels)
Two motors means theoretically 0.369 watts each. This is of course very low and I feel like that is because I didn't factor in the friction. But what is a way to calculate the friction? Is there a standard way of estimating it using the weight of the device?
Thanks
