Numbers on the Robot

We were wondering if we could use black reflective numbers on the robot.

-Thanks for any help

Specifically the same style of material you would use on a mailbox.

R2 Team numbers must be displayed on the ROBOT and meet
the following criteria:
A. consist of numerals at least 3.5 in. high, at least 0.5 in. in stroke width,
and be black in color with a white background extending at least 1 in.
from the edges of the numbering,
B. be positioned around the ROBOT such that an observer walking around
the perimeter of the ROBOT can unambiguously tell the Team’s number
from any point of view.

Figure 4-1: Team number display
The intent is that the Team’s number is clearly visible and unambiguous so that Judges, Referees, Announcers, and other Teams can easily
identify competing ROBOTS. Consider the numbers as the license plates for your ROBOT.
NOTE: Impact font, size 362pt., shown in Figure 4-1, meets the stroke and height requirements for all digits.

Reflective could be troublesome if they are retro-reflective and at a height that may interfere with another team’s vision systems.
