Robots are becoming more and more common in our everyday life, so life without them has become unimaginable. This is one of the reasons why technology around robots is developing faster and faster. The way in which an industrial robot is used correctly is shown, together with its technical specifications, which parts are necessary for operation and the principle of operation. Working with any robot always requires a correct program so that the robot knows what its task is and how to perform it. An example of a program that is often used in the industry today is shown and how it works is also explained. The thesis discusses the connection between the robot and the PLC, and the method of establishing communication. Instead of the robot, the PLC performs the more demanding part of the work, i.e. mathematical and logical operations, which as the end result represent commands to the robot in the form of bit or word type variables. Finally, the work with the HMI interface is described, how it is edited and put into operation. The HMI interface is a device through which we can control the robot. These include certain commands in the form of buttons and images. The image on the HMI device represents the current position of the robot, and as the robot changes position, the image that is visible to the end user also changes in order to simplify the operation and monitoring of the robot.
