Based on radio-frequency identification (RFID), this paper designs an upper and lower computer control system to solve the problems of existing indoor mobile robot positioning techniques. The Matlab graphical user interface was employed to build the software platform (i.e. upper computer) of the information database in the mobile robot positioning system, while the STM 32-based mobile robot control was adopted to design the hardware control system (i.e. lower computer). In addition, the data transmission between the computers and the robot was realized using the serial communication technology in Matlab Toolbox and CC2530 wireless communication, laying the basis for robot positioning. The proposed control system was proved effective in enhancing the robot’s responsiveness and controllability and solving the problems of the lower computer (e.g. low computability and insufficient storage). This research marks the trend of mobile robot positioning technology.. RÉSUMÉ. Basé sur l'identification par radiofréquence (RFID en anglais), Cet article conçoit un système de contrôle de « upper and lower computer » afin de résoudre les problèmes posés par les techniques de positionnement de robots mobiles d'intérieur. L’interface utilisateur graphique de Matlab a été utilisée pour créer la plate-forme logicielle (upper computer) de la base de données dans le système de positionnement de robot mobile, tandis que la commande de robot mobile basée sur STM 32 a été adoptée pour concevoir le système de contrôle de hardware (lower computer) . En outre, la transmission de données entre les ordinateurs et le robot a été réalisée à l'aide de la technologie de transmission série de la communication sans fil de Matlab Toolbox et CC2530, jetant les bases du positionnement du robot. Le système de contrôle proposé s’est avéré efficace pour améliorer la réactivité et la contrôlabilité du robot et pour résoudre les problèmes de l’ordinateur inférieur (par exemple, une faible calculabilité et un stockage insuffisant). Cette recherche marque la tendance de la technologie de positionnement de robot mobile.
