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.

Description

technical field [0001] The invention relates to the technical field of combined positioning in complex environments, in particular to a mobile robot IMU / UWB / code disc loose combined navigation system and method using multi-mode description. Background technique [0002] In recent years, with the rapid development of computer technology, information technology, communication technology, and microelectronics technology, mobile robot technology has been widely used, and the research and application of target tracking technology for mobile robots has gradually become a research topic in this field. hotspot. However, in a series of complex environments such as weak external radio signals and strong electromagnetic interference, it has a great impact on the accuracy, real-time performance and robustness of the target carrier navigation information acquisition. How to effectively integrate the limited information obtained in the indoor environment to meet the high navigation accur...
