Good evening,
The stand number tag for the SIMA are simple printed sticker, like you have on your robot. The aim is to know from which team come the SIMA in case of missing SIMA on table or on homologation (and yes we aready have the case).
You can put it everywhere you want on the SIMA (and yes you can put in under the SIMA), it must be readable, and not damage if you open the SIMA.
Regards
