I do not believe that this had come up yet, but I'm pretty sure that if you check out the indpection list (posted on the USFIRST site), and then reference the rule on entaglement (I'll edit this post and give a specific rule so you don't have to hunt, but I've got somewhere to be at 10:00 (and it's 9:58 )), you will find that it considers any space larger than 4in^2 to be a hazard. An uncovered robot would most certaintly then be considered a hazard.
