Might I suggest that if you want comments, perhaps you should post a more informative picture. A robot hint is not the game hint, and unless your number starts with a seven, and ends with a one, and is only two digits long, then people are not going to crazy trying to figure it out. They're going to peruse by it, and then post comments about an actual robot design, when/if you post one.
EDIT: That's some pretty thick stuff.
