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 [...]

Sabertooth Motor Controller 25×2 Review

Sabertooth Motor Controller is absolutely perfect for robotic systems. I used these motor controllers at my Tsunami and Fusion sumo robot projects.  It has big power connectors.  I never experienced bad problems like Pololu motor controllers. Sabertooth Motor controller has four interface methods: R/C mode : For using r/c receivers especially. Analog mode:  My preferred choice. Serial Packetized Serial Some Notes About Motor Controller: For analog mode control you have to add one capacitor (100nF) and resistor (1K-4,7K) to your interface. After you can control sabertooth [...]
