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 [...]

How to Make a Good Sumo Robot

How to Design & Make a Good Sumo Robot In this article, I will share my sumo robot design and build secrets. Firstly we are starting with sumo robot parts. Please click the bottom image for bigger visual, in that article I will go deeply at each section for sumo robots.  We can divide sumo robot to 3 subdivision:Mechanic System –  Structure Electronic System – Organs Software system – Robot’s spiritFirstly we starting mechanical System. The mechanical system covers motors, gearing, wheels and robot’s [...]
