The best bet is to take four scales and place them on each wheel. The fractional weight should be the weight of the two driven wheels divided by total weight.
That makes sense, but I'm still a bit confused. We are considering using a 6 wheeled design this year but, as it's not built yet, I can't check the weight on each wheel yet. I was wondering if you knew any common or average values for either 6 or 4 wheels?

Also, I was unsure if the calculation should be the sum of the weights on one side divided by the total robot weight, or something else. Thanks in advance.
