Designing and Prototyping of a Hybrid Robotic Lawnmower

In this paper, the designing and prototyping of a hybrid robotic lawnmower is presented. The main system components required for functionality are briefly described. All parts of the system are selected in order to enable coordinated operation of electrical and mechanical components. Robotic lawnmower prototyping is preceded by a design process that consists of a phase of selecting the main components and CAD modeling of parts and components. The goal is to position components and parts of the chassis with maximum compactness. The main subsystems of the prototype, the differential drive configuration, and the hybrid subsystem with a belt transmission for starting the alternator and the lawnmower blade are shown. The parts of the subsystem were tested and the final testing of the robotic lawnmower in the case of remote control was carried out. This prototype was made with total costs many times lower than similar commercial robotic lawnmowers.
