APPLICATION OF EDUCATIONAL ROBOTS IN TEACHING

By Armin Čelarević, Ilma Mrakić

Robots in education fall into two categories: robots used to teach children about STEM subjects and the more recent application of robots as teachers. The use of robots in education is largely unknown to both researchers and teachers. Developers and educators have questions about essential applications for robots used in education. Educational robots are used to enable students to acquire skills in a range of science, technology, engineering and mathematics disciplines, which are increasingly important in a world where technology is advancing rapidly. The potential for robotic technology to have a profound impact on society, both economically and socially, is enormous. The way people live and work in the world is largely influenced by technology. In order to make learning more pleasant and easier, the education sector is adopting robot teaching assistants in schools. Robotics can be used in education to help develop new methods and strategies. Robotics makes learning easier and thus introduces students to robotics at a young age. In primary education settings, students can learn how to build and program a robot to perform a range of basic tasks.

ACHIEVING MORE EFFICIENT WORK FOR CONSTRUCTION COMPANIES WITH THE APPLICATION OF INTELLIGENT INFORMATION SYSTEMS IN REAL-TIME

By Mladen Radivojević, Nehad Gaši, Dina Vrebac

In this paper, we propose the use of intelligent real-time information systems that can provide all the necessary data, information, and knowledge for more efficient work and decisionmaking in construction companies. An appropriate data warehouse is necessary for the functioning of such an information system. Here we will suggest some new ways to fill them. To more efficiently collect some of the necessary data for the warehouse, we will propose the use of drones, the Internet of Things, and the 5G network to access them. Based on the processed data and the obtained information and knowledge, we will propose the use of intelligent real-time information systems in a construction company. Such an intelligent system can provide a construction company not only with more efficient work and decision-making but also with a competitive advantage. We will also list a small part of the new technological solutions that a construction company needs for more efficient collection and faster transfer of necessary data to the data warehouse, and more efficient connection of machines, devices, and things.

HEAT PUMPS

By Azra Hrustić, Nehad Gaši

Heat pumps or heat pumps are devices that have the ability to transfer energy. Pumps transfer the energy they take from the outside and transfer it to the inside of buildings, i.e. to places where heating or cooling is needed. The heat pump consists of the following parts: compressor, expansion valve, gas (for example R410) or heat transfer fluid, evaporator and steam condenser. Energy from renewable sources (earth, water, air) enters the pump evaporator. Then through the pipe system, the gas that has taken on the energy goes to the compressor where the pressure and temperature increase. The next step occurs in a welded exchanger system where the heat of the gas is transferred to the heating/cooling system. After giving up the heat, the gas returns to its original temperature and goes back to the evaporator to start the process again. In order to classify them more simply according to criteria of general interest, we divide them according to: energy sources from nature - free energy sources they use, power and characteristics. For example, according to the energy they use (free/natural) we divide them into: air-water heat pump, ground-water heat pump and water-water heat pump. Heat pumps have a combination of two meanings in their name. The first word indicates the energy used, and the second the energy transmitter in the installation
