what size of silicon wheel fits into this motor? Admin Reply: JS5230, JS4320 wheels are suitable. At JS4320 wheel model we have 4mm and 6mm center hole options. only Suitable with 6mm Holed model.

The best motor i found to have good speed and good torque, it holds 12v without problems

The Rpms are before the 48:1 reduction? I want to know the final speed of the robot. Is it 400 rpm / 48 * 2 * PI * WheelDiameter/2 400/48*2*PI*26/2 = 680 mm/min This is too low for what i would like for the robot. For a 800mm diamenter sumo table, it takes more than 1 minute to go from one side to the other... Is something wrong in my numbers, or i need less reduction motor? -------------- Admin Reply: Always, our RPM values are final outputs of DC gear motors. Standalone motor speeds usually higher than 10K Rpms. So these values are "after" reduction. That you can use at your robot directly with these datas.

These motors worked well when put 4s battery. Their speed and torque allowed us to win Kazakhstan National mini sumo championship. And same mini sumo robot was powerful enough to win local non-magnetis Mega Sumo Tournament. :)

If you have soldering skills this board is very easy to work and effective for mobile robotics. My students successfully use the board on national competitions.

We ordered 100 pcs two months ago. And now ordered 100 more for organizing local mini sumo tournament. Thanks to JSumo company and Mr.Firat personally for giving good discounts and gifting two referee remotes. P.S. All start modules worked well, no any complains from customers. All of the above will level up our tournament.

Please can u tell me what comes with robot, is everything included or do i need to buy anything separately, e.g battery??

This is the winning mini sumo (antweight) kit. It is great overall design and excellent CNC machinery quality. Easy programming using Arduino IDE and has a lot of potentials for customization and more sophisticated algorithms.

This is the best frame for mini sumo (antweight) robot. Excelent CNC Machinery quality. Great Ssumo robot design.

What is the size?
