    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.

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