Wheel encoders are devices that allow one to measure the precise speed or distance a wheel travels.
These are helpful for precise movement, allowing a robot to turn exact angles or move exact distances.
Wheel encoders can provide information for odometry and be utilized in localization problems. In the case of an inverted pendulum knowing the exact rotation of the wheels is critical feedback in the balancing equation.
