in the rules it is stated:
3.2.1. Any robot kit or building blocks, either available on the market or built from raw hardware, may be used as long as the design and construction of the robot are primarily and substantially the original work of the students.
I want to replace the EV3s Brick for my student with a similar concept I developed. I would build the replacement Brick, while the students do the programming and general incorporation of the Brick into their robots.
My question now would be to what extent this creation would have to be available on the market. Would I have to sell it, or would simply uploading the circuit diagram be enough for example?
Thanks in advance,
