that's not nessisarily true, a robot with more motors will have more theoretical pushing power than one with less, while also having more speed. when talking about the same number of motors though, that is true.

@AllenGregoryIV
when you factor weight and CoF into these calculations it will cause most robots to have a max pushing power of about 220 lbs because their wheels will spin before their motors will stall. it is true that a lighter robot will be able to push less but the majority of teams are pretty close to their weight limit. now for ground friction, every robot of equal weight should have the same ammount of friction no matter how many wheels they have because force of friction= (CoF)*(Weight)

now on my chart your robot scores a 15.78 because it has theoretical pushing force of 1083 lbs and velocity of 5.4 ft/s. if i had put this in counting CoF and weight it would most likely end up at about 220 lbs, the limit because of how much friction you can get with a 120lb robot+battary+bumpers.

now for drivetrain inefficencys: if i remember correctly that calculated currently as the .81 (81%) in the two RPM columns, a figure i think i borrowed from what the JVN design calculator had. (this could easily be made into another column to be entered by hand, but how many teams know how efficent their drivetrain is?)

i hope that this helps clear some of the confusion up
