The invention discloses an indoor multi-mobile-robot cooperative system based on a fuzzy algorithm and two-dimensional code self correction. The system comprises multiple rotor bodies and two-dimensional codes distributed at different indoor positions. Each of the two-dimensional codes comprises a QR code which represents the position coordinate of each two-dimensional code in an indoor two-dimensional coordinate system. Each of the robot bodies is provided with a single chip microcomputer, an acceleration meter module, a gyroscope module, a two-dimensional code recognition module, a communication module, and an ultrasonic sensor. The system has the low cost, the efficient path planning can be realized, multiple robots are in cooperative operation and the conflict is avoided, and the working efficiency is high.
