4 Vroombas were submitted. One did not compile and so I did not run it in the Challenge.
The Challenge rooms results were scored out of 4 points (rather than 2), but otherwise follow the same rules as for grading. Remember you need at least 1.5 points to place on that room and so earn EC. Though each Vroomba was run on each room multiple times (usually 50), there is still some element of luck on where your Vroomba starts in the room. If we ran this again, the placements might vary slightly.
Well done to those that submitted! I'm sorry there weren't more contestants.
