RESEARCH ON THE MOBILE BODY’S NAVIGATION SYSTEM OF THE PLANEL INSTALLED ABSTRACT Along with the development of robot technology, building robot as a branch of the industrial robot technology has e an important trend. The panel installing robot have been became a research focus. In the actual interior architecture decoration environment, based on the puter cooperation or unmanned navigation of mobile body has been e the key of research on the mobile body panel installing robot. With the support of 863 national projects " Research on the system of panel installing robot " (item number: 2007AA04Z240). In this thesis, with the mobile body’s navigation technology have been further research, By building structure CAD constructing of electronic environment map, using environment electronic map-landmarks for mobile body positioning and the mobile body path planning. This paper's major initiatives and innovations include: In this thesis, the mobile body’s prototype was selected and put forward their respective reform program; summed up the analysis of automation in production of panel installation process, detail plan the installation process and the robot moving step. For mobile body positioning problem, according to the construction of electronic map and the artificial landmarks, this study essfully applied to build the robot vision system hardware platform, designed and implemented plete set of positioning algorithm. By experiment, the validity of the algorithm is verified. Based on the mobile robot path planning algorithm, this study proposed the method using visibility graph and the Dijkstra algorithm can view and search the shortest path, according to two problems of the algorithm, carried out to simplify and optimize this study, through the experiment verifies the effectiveness of the method. The software system designed based on LabVIEW, complete mobile body navigation software system design; By simulation experiments, the result verified the correctness of th
