we just had the the old discussion again:
Teams are using IR distance sensors.
The open and lightweight rules are absolutely clear : "the robot must not emit infrared light".
But then there comes the next sentence telling that IR distance sensors are allowed as long as they do not distract the other robot.
I do not like this. It means arguments on the field whether the distraction is high or low and it often
leads to "why do you not use IR-Filter on your camera"
So here is my suggestion:
in lightweight we eliminate the permission to use IR-Sensors at all.
Teams can use ultrasonic sensors.
It is much better to know this from the very beginning than being told during the match that the sensors are not allowed.
And in open we cancel the whole chapter.
In open we can expect the teams to use IR filters on their cameras.
There we have to be aware of colors and IR light should not be banned at all.
If you all agree, we could change this right now at least for open, as this rule change does not restrict any robot that is already built, but prevents unnecessary discussions. So this could be a rule change even for 2020.
