Urgency of the research. In the context of design of new, improved devices or technical systems containing electronic elements, we are increasingly encountering the concepts like mechatronics, mechatronic systems, mechatronics system solving approach or just simply mechatronics. The impact of mechatronics is most noticeable in mobile mechatronic products, especially in the automotive industry, where mechatronic systems are increasingly being used. Target setting. The design a wheeled chassis with improved ability to cross rugged terrain. Its indivitual parts are subject of simualtions and stress ananlysis, which confirmed the advantage of the chosen design and mobility of the chassis. Actual scientific researches and issues analysis. Designing a robot for a specific purpose always involves several steps. Before considering the design of a robot, it is necessary to determine the environment in which it should operate. The problemof four or more wheeled chassis arises when the wheels are unsprung and the unevenness of the terrain surface causes loss of wheel contact with the terrain surface and thus loss of traction. Uninvestigated parts of general matters defining. The question of the physical design of a mobile robot is uninvestigated, because it will be solved in future. The research objective. The main aim was design and stress analysis of individual parts of the mobile wheeled robot with improved ability to pass through rugged terrain.The statement of basic materials. The chassis is based on five modules which are connected between each other. Its steering ability against each other is determined by the upper connection cover. Two modules integrated between wheels are for storage, which can be used for battery sources or auxiliary control. Conclusions. All construction parts of this mobile robot were designed in Solidworks software, taking into account thesimplicity of the structure and its ease of manufacture. The mobile chassis was tested in various terains simulations, where all his movements and terrain adaptation were monitored. The mobile chassis structure was recalculated from the point of view of the mechanics theory.
