Tutorial videos

Hello! We are starting a series of video tutorials that will help you get ready to participate in the Kalashnikov TechnoFest robotics festival. We will examine in detail the basic things related to programming microcontrollers in Arduino IDE, designing 3D models of various parts. We will review the basics of working with a 3D printer and laser cutting machine. We will pay attention to the peculiarities related to each direction of the festival – mobile robots and drones competitions and Polytechnic Olympiad.
