What is the best way to mount odomentry wheel?

@9935E, if you would like to see VEX Worlds winning robot’s tracking wheels mech and odometry algorithm that goes with it, then it is your lucky day:

But, if you will insist that 5225A’s design is not accurate enough for your not yet built robot…

Then I must, regretfully, conclude that you are either trolling or hopelessly unable to accept or understand good advice that @kevjar and @Ethan5956F were kindly giving to you.

Please, don’t treat forum as a chat, learn to love search function, and take some time to read thoughtful advice that more experienced members are sharing with you.
