some thing about motor encoder

A new word is odometry , which is geometry parameter you can get from robot control, such as x and y position after robot moving.

If you want to calculate odometry automatic , you should need encoder on motor .\

Encoder Resolution=PI*Diameter/PulsePerRotation/gearRatio.

First time , I didn't get what gear ratio mean, so I get the wrong encoder resolution.
