In addition to virtual reality and additive technologies, collaborative robots are major hardware technologies important for the integration of Industry 4.0 strategies. The work includes the discussion of collaborative robots and their applications in industry, the use of the ROS system and its libraries, as well as interfaces and programming of the movements of the collaborative robot for the use in a modern assembly site. We integrated the collaborative robot, the company Franka Emika, Panda, into the software ecosystem of ROS. The robot was operated via the RViz application and via the Moveit! interface, with scripts written in the Python programming language. We created a robot simulation in Gazebo, and integrated it into the Moveit! interface, which allowed the use of the same program scripts as on a real robot. In the first part of the analysis, of the use of a robot in a modern assembly site, we studied the success of controlling a real robot and its simulation, according to the level of success of controlled movements. In the second part, we placed objects in the virtual environment of the robot and studied the trajectory of the robotic arm when evading from virtual objects. We have taken the findings into account and changed the settings in the interface package, and changed the program scripts in order to increase the level of success of the movement in the order of reduction its trajectory.
