Tire and wheel radius

#1

Hello, I would like to use the wheel speeds sensor data but see that it is in rounds per minute. What is the radius (or diameter) of the tire/wheel assembly that can help me find the linear velocity of each wheel?

#2

Hi. The radius of the wheels is (WRONG! See below). Note that I am working on this PR to visualize vehicle speed vs. wheel speed.

#3

Hi, thank you!

I will take a look at the PR and let you know if I have any questions.

It turns out the number I gave you above is wrong and from another model. We’ll have someone measure it again, my current guess is ~0.305m.

#5

We measured 24" diameter, so 0.305m radius is right.

I see, thank you! I also see that you updated the tutorial code as well.
