Nice, that looks much cleaner and the numbers are much more noticeable. Just one thing. Have you checked how big that logo would be if the numbers were enlarged to 4" high and the rest of the logo was enlarged to scale? You just want to make sure that this is at a reasonable size so the logo with the numbers can reasonably fit onto the robot.
I mean, you don't have to... but it would look freakin' awesome...
