Laura, It's been tacitly understood that marking the robots to distinguish them from each other, especially where there were multiple teams from a school or other location, has been inevitable. Also, once you do it, it could be financially infeasible to undo. For attachments and other components like sensors, it would be seen as more consistent with the rules not to have those marked. So, if possible, swapping with unmarked sensors would be preferable.

Raised a red flag for me- is that "illegal?" We can swap out the sensors if it is against rules.
