This paper describes the project of a brushed DC motor controller for the locomotion system of a combat robot with the aim of developing the national technology, since similar controllers are only available in the international market. Also is presented in detail the thermal dissipation study developed and the calculation of track width in printed circuit boards so that the controller supports currents of up to 80 A. The project also counts with peripherals such as datalogger, telemetry and a sensors network capable of monitoring voltage, current and temperature. Currently the device is fully working, with printed circuit board already assembled and tested in laboratory.
