By developing things and integrating them into the modern world or connecting them to the Internet, it is no longer easy to say when mechanical equipment becomes electronic. Mechatronics is an interdisciplinary discipline that integrates mechanical and electrical engineering, but has also included robots, electronics, control and regulation, and programming in its growth. Mechatronics engineers use tools from all these domains to design systems that are suitable for modern man. Pneumatics are widely used in industry for their durability and resistance to electromagnetic interference or pollutants, and are increasingly finding applications in mobile robots and transportation. The primary concept of operating a pneumatic system is to convert mechanical energy into compressed air energy, which is subsequently converted into another type of mechanical energy. This is often achieved by using an air-filled cylinder, which moves the connecting rod. Likewise the main components of the pneumatic system are executive elements, which can be divided into two types: those with limited movements (translational or rotary) and pneumatic motors. The most common executive element used in pneumatic systems is undoubtedly the cylinder with translational movement. Likewise, the paper will show how pneumatic and electropneumatic systems work through the presented schemes and PLC programming, and this can be seen especially in the last chapter, where an example of the functioning of pneumatic control is shown.
