    Nearly all optical mouse uses optical sensor IC that communicates with the outside world using SPI protocol. The movement is reported as data in both X and Y direction.

    You can interface with it using SPI to your MCU of your project.

    Get more information from this link

    Interfacing an optical mouse sensor

    or search Google using phrases like "Optical mouse position sensor robot"
