A method for accurately tracking and controlling robots includes capturing a first image of a first matrix code labeled on a first mobile robot at a first time by one or more stationery cameras, wherein the first matrix code is encoded with an identification that uniquely identifies the first mobile robot, correcting a tilt of the first image to produce a first corrected image that shows the first matrix code in a substantially rectangular or square shape, extracting the identification to uniquely identify the first mobile robot, calculating a first position of the first mobile robot based on the first corrected image by a computer system, and controlling a movement of the first mobile robot based at least in part on the identification and the first position of the first mobile robot.
