Is this Equation Correct

The weight which a robot can hold depends on the strength of what supports the weight.

Why do the number of wheels, strength of drive, or speed at which the robot is travelling have anything to do with how much weight can be held?

What units are you using for torque? For wheel radius?

Number of wheels would determine how weight is distributed to the ground. Actually, that would only be number of wheels in contact with the ground. Four 3/8 axles can support far more than one.
