The thesis presents the development of an integrated robot controller based on the ATmega32U4 microcontroller. KiCad EDA and Arduino IDE software packages are used for the design and programming of the PCB. Initially, we discuss the theoretical basics of robotic controllers and the process of designing and manufacturing printed circuit boards. Then, the components used and their interaction are described: communication of the microcontroller with the wireless connectivity module and inertial measurement unit, control of the DC electric motors with a H bridge driver and the system for managing signals from rotary encoders. Finally, the board's performance is proven by controlling a line follower robotic base, setting the speed wirelessly from the web site of a purpose-built server.
