Nowadays the range of tasks that robots are capable of performing is becoming increasingly wider. Production processes are becoming ever faster and more accurate with the assistance of robots. Acquiring the knowledge of how industrial robots operate and how they are controlled has an important role in education.
As a part of enhancing the robotics laboratory at the Department of Automation and Applied Informatics, efforts are made to develop an industrial process model, which incorporates a conveyor, sensors as well as interceptors. By using the established work station, students can acquire more in-depth knowledge and experience about the features of a particular production process.
My task was to develop an integration hardware, which is capable of handling encorders, work piece feeders and interceptors. The circuit must manage inputs and outputs of 24 V signal level. The device is featured to cope with communication in PROFIBUS system, which is widely applied in industrial environments.
I give a description of the circuit design process in my thesis. I present how the schematic was developed, how the components were selected and finally how the printed circuit board was designed. Then I demonstrate the structure of the firmware.
