Abstract

The invention discloses a mobile robot IMU / UWB / code disc loose combination navigation system and method adopting multi-mode description. The system comprises a UWB reference node, a mobile robot and a data acquisition module, wherein the UWB reference node communicates with the mobile robot and the data acquisition module; the mobile robot communicates with the data acquisition module; the UWB reference node is used for measuring a distance between the reference node and the mobile robot; a moving state of the mobile robot can be judged according to a speed acquired by a code disc fixed on the mobile robot, and a calculation error can be respectively estimated according to different moving states. The system and the method have the beneficial effects that the system and the method can meet the requirements on high-precision positioning and orientation during indoor mobile robot navigation. The system can be used for positioning the mobile robot at high precision under an indoor environment.
