1. A method for accurately tracking and controlling robots, comprising: 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 a first identification that uniquely identifies the first mobile robot; extracting the first identification from the first matrix code of the first image 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 in communication with the one or more stationery cameras; and controlling a movement of the first mobile robot by a computer controller via wireless communications, based at least in part on the first identification and the first position of the first mobile robot, wherein the computer controller is in communication with the computer system.
