The thesis presents the upgrade of a Torpedo TD 5506 A tractor and a forestry winch, in which the existing mechanical system was adapted to modern operational and safety requirements. The main goal of the upgrade was to enable remote control of the winch and tractor functions, thereby improving safety, ergonomics, and overall work efficiency. The developed solution is based on the integration of pneumatic actuators, electro-pneumatic valves, an Arduino microcontroller, a stepper motor, relay circuits, and a radio controller. The applied methodology included analysis of the existing system, design of pneumatic and electrical circuits, development of control modules, microcontroller programming, and testing of the complete setup. The results demonstrated reliable operation under all test conditions, ensuring precise and user-friendly control of the winch. The system proved to be cost-effective, robust, and adaptable for use with other forestry attachments. The presented upgrade represents a successful integration of mechanical, pneumatic, and electronic components into a unified mechatronic system.
