New Sumo Robot Gears Added to JSumo Shop

Blazing Speed Sumo Robots! Achievable! Sometimes when you watch sumo robot videos, you see how much they are fast. Some friends asking which motor you are using or which voltage? For making fast robot you need to change three things: Motor Voltage (DCX, RE40 or RE35 Types 12-18-24V Nominal Values) Wheel Size (35-50 millimeter sizes) Reduction (Cha-ching!) Our secret was making lower reduction rat... »

I am not beginner at motor controllers or at least implementing motor controllers to robot systems. When I bought I was very excited and curious about these motor controllers… But I get disappointed with performance and lack of guarantee. »

High Current Dc Motor Controller Project

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... »

First Versions Of Sumo Robot Controllers

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 de... »

Aluminum Advantages Easy to work Light Disadvantages Not for welding, for welding some special systems needed (TIG welding). Aliminum Laser cutting is harder than other metals. Not resistant to big impacts. It can bend. Tapped holes can be easily stripped. Steel Advantages Hard Easily weld (It’... »
