High Current Dc Motor Controller Project

For this year’s sumo robots, I have to design new better motor controllers. At first designs, I used big power mosfets, through hole components. With experience, I made better, concentrated PCB. I used this boards at my all sumo robots (Shadow, JSumo, Fusion2) It uses 4 Power MOSFETs and HIP4081A MOSFET driver. I fabricated only 20 pieces as prototype. I made 2 PCB in design. The bottom deck is power system (MOSFETs, MOSFET driver,s, regulators…). Motor Driver’s Bottom Layer, Bottom side. Upper Deck [...]

First Versions Of Sumo Robot Controllers

 Last year I designed some sumo robot controller circuits. All components (Motor drivers, voltage regulators, Arduino) in one board.   Firstly I made some test with breadboard. This wasn’t last design. I doubled mosfet transistors at last design. Last through pin design. It was like an art to make this board. I used at Shadow sumo robot. After I used smaller SMD motor controller designs. Also Design’s one fault is not having optocouplers (Very big Fault..)
