Wheel grip
Wheel grip
According to the equation for calculating friction, the weight of the car and the material for the wheels matter, but the width/contact area should not. Ignoring the material and diamater of the wheel, is there any reason why a wider wheel like a banebot wheel would be better than something like a CD wheel?

Re: Wheel grip
I think the robot wheels have some sort of traction thing on them, but I'm not sure. As for width, I think the wider the wheel, the more mass it has, providing more weight, but also increasing the rotational inertia.

Re: Wheel grip
yes, the wider wheel generally applies more force than the thinner wheel.Things2do wrote:I think the robot wheels have some sort of traction thing on them, but I'm not sure.

The force of friction is proportional to the pressure and the contact area, so when you keep the normal force constant, increasing or decreasing the contact area doesn't affect the force of friction.
