1. For the "Weight on Driven Wheels", that weight is distributed evenly among wheels, right? (say 25% if there are 4 wheels)
2. What is the "Speed Loss Constant"?

Thanks in advance!

Speed loss constant accounts for the difference between actual speed and free speed of the motor. You can pretty much leave it at 81% for most FRC applications.

For "weight on driven wheels" if you have a 4WD robot with all wheels being driven then you would set that at 100%. If 2 of the wheels where non driven casters that would be 50% assuming a perfect weight distribution. Also for the purposes of this calculator omni and mecanum wheels are the same as traction wheels and wheel drop is ignored.
