Technically, the robot can legally be 20.78" long (12" x sqrt of 3), but that would require the minibot to be needle thin at the ends that touch opposite corners. It is also somewhat impractical, since the deployment line is at 18". You could deploy at an angle, but your hostbot might still be in contact with the minibot when it climbed above 18", resulting in a penalty.
