Who we are
RoboFuze, based in Prague, Czech Republic, is the maker of the official RoboCupJunior Soccer IR ball and the RoboCupJunior Soccer communication module, which links each robot to the referee's RCJ Soccer RefMate app.
Our products are designed by an author of the RoboCupJunior Soccer rules, so they are built around what the rules require and what happens on a real competition field.
Why open design
RoboCupJunior is about learning. That's why the design files are public on GitHub: schematic, PCB, firmware and 3D-print files of the IR ball, and the schematic and firmware of the communication module; the licensing section below explains what each licence allows.
Teams can see exactly how the hardware works, write better code for their robots, repair their own equipment and build their own for practice. Buying from us gets you a finished, assembled unit and funds further development.
How it's made
Factory-assembled, hand-finished
Our assembly partner machine-assembles the boards. In Prague we hand-solder the remaining parts, assemble every ball and module and inspect each unit before it ships.
-
Designed in the open
Schematics and firmware of both products, plus the IR ball's PCB and 3D-print files, are on GitHub for everyone to study.
-
Finished and inspected by hand
Every ball and module is put together in Prague, and each unit is inspected by hand before it ships.
-
Built for the rules
Designed by an author of the RoboCupJunior Soccer rules, for real competition fields.

Covered for 24 months
24 months of statutory rights for faulty goods. See our Refund policy and Terms.

FAQ
Frequently asked questions
Can't find your answer? Email info@robofuze.com.
Do you ship internationally?
Yes. We ship internationally from Prague, Czech Republic. Where checkout offers a shipping option for your destination, the cost is calculated there. If checkout offers no shipping option for your destination, email info@robofuze.com for a quote before ordering.
How do pre-orders work?
When a product shows Pre-order, you can order and pay now and we ship when the next batch is ready. We produce in batches, so we don't promise fixed dates. Need it for a particular competition? Email info@robofuze.com before you order.
Is a battery included with the IR ball?
No. IR balls ship without a battery, which keeps parcels lighter and easier to send. You need one 18350 Li‑ion cell and a charger. Our IR ball battery guide explains which cell to buy.
Will I pay customs or import duties?
Possibly, for orders outside the EU. Prices and shipping costs don't include customs duties, import VAT, local taxes or carrier handling fees. These are set by your country's authorities or the carrier and are paid by the customer. Please check what applies before you order.
Can I return an order?

To withdraw, email info@robofuze.com with your order number (you may also use the model withdrawal form in our Refund policy). Send the goods back within 14 days of telling us.
We refund the price you paid, including the standard shipping cost, within 14 days of receiving your withdrawal; we may wait until we have the goods back or you have shown that you sent them, whichever is earlier. Return shipping is paid by you.
You may handle the goods as you would in a shop to check them. You are only liable for any loss in value caused by handling beyond that.
You have statutory rights for goods that are faulty or not as described (24 months from delivery). Email info@robofuze.com and we will repair or replace the item free of charge, or reduce the price or refund you where repair or replacement is not possible.
Full details are in our refund policy.
