Draft rules for RoboCupJunior Soccer 2022 released

[david]

Hi @stiebel ,

@stiebel

But then I read the line: “For the 2023 rules, the Soccer Committee intends to limit the voltage to 9.0 V
nominal for both leagues.”

This is not yet set in stone, but it is a consideration, could have been phrased “is considering”…

@stiebel

So If you want to reduce power from 15V (where I still do not understand the reason), than you have to consider these voltage steps.

The idea is to have more passing, kicking and strategy by slowing robots down (i.e. more preception and planning, less faster motors winning games).

@stiebel

This will have only one effect: all the motors and motor drivers the teams kept buying over the last years will be pushed beside to buy some other motors with higher currents to provide the torque needed to run the robot. This will have no effect to reduce speed.

I’ll cross-post your assertion to the battery voltage thread and respond in technical detail. Please do post dissenting views there: Resolve: lowering voltage limits to 9V will significantly reduce robot speed. Show me the data! - #4 by david

@stiebel

If - at all - reduce to 12V for all classes. This could possibly bring teams to user their existing stuff, but if you half the voltage of the open2vs2 robots, you will generate plenty of e-waste without any need and without any benefit.

You make a valid point about not making equipment obsolete - that should only be done if it’s worth it for the improvement in gameplay, please also argue this in the battery thread linked above.

Cheers,
David
