Group navigation improvement for a robotic group is an actual task. This problem can be solved by optimizing communication within this group, even for a heavily cluttered environment. Also, optimized communication can be successfully used for effective penetration into the studied sector. The article solves the problems that arise when the robots group navigation acts. It describes the use of a technical vision system (TVS) based on the principle of dynamic triangulation with subsequent transmission of data of interest. Two different simulations in order to optimize the fused database for better path planning aiming the improvement of electric wheeled mobile robots group navigation in unknown cluttered terrain are presented. It permits more efficient path-planning of the RG
