We want to use simplified QR codes on the robots. The robots would then be able to accurately see each other from a medium to short distance. We would like to experiment a shared localization system through that method.
We'd like to make sure that this is allowed, granted that the color markers will remain on the robot as usual and that our feet will be black.
Law 4 Players, section "Colors" :
Robots must be mostly black or of dark grey color (i.e. RAL 7011 Iron Grey or darker) and non reflective. Robots may also be colored in aluminimum-like silver, grey or white but then their feet must be colored black.
