This year, we participated in the AMPER trade fair once again - the largest international trade fair for electrical engineering, energy, automation, communication, lighting, and security in both the Czech Republic and Slovakia. We presented a drawing robot (Michal Adamík), a radiation camera (Nikola Kurucová), and the Enviro station and water purification with diamonds (Tomáš Vincze). In addition to us, 410 other exhibitors from 23 countries participated in the exhibition.
