EDC: Frequently Asked Questions
Updated January 31, 2016.
- Can graduate students participate in the competition?
Yes! All students, both graduates and undergraduates, qualify for winning awards in EDC.
- Can we include (a) team member(s) who graduates before the competition date?
You can, but all team members must be university students as of the day of the competition to qualify for monetary awards. That being said, your team would still qualify for the other non-monetary awards and titles, and the competition would still be as fun!
If you would like to participate as a hobbiest, please tell us so in the registration form.
- How are the winners decided?
The overall score of the team is decided by the following; 60% of the score is based on the performance in the games, while 40% are decided by the technical judging. More details about game scores here, and about technical judging here. The two teams with the highest overall scores will be given the first and second place prizes.
More awards are distributed to teams who show proficiency in certain areas, which will be announced later.
- Are teams required to participate in all 3 games?
All teams are scored on all of the 3 games. A team can choose not to play a game, which will get them the minimum score possible without penalties.
While the overall prizes includes the scores on all 3 games, and such not completing a game has a negative impact on your overall scores, teams may still be able to get individual awards for their performance in games, or other auxiliary awards.
- Are the borders of game areas physical boundaries, or are they imaginary?
Unless designated as curtains, the borders are imaginary in the sense that no physical barriers will stop boats from leaving them. The curtains are designated as thick black lines in the drawings of the three games here.
There will be some marking for the borders however so that judges can tell when boats leave the game area, which they will be penalized for as per the rules.
- The rules mention curtains. What are they?
The curtains are as showed in the 2D CAD drawings here in thick black lines. There are three curtains; one between the two lanes in King of Speed, and the other on the far end of the Obstacle Course, sharing an edge with the far end of the Water Tanker, and the third being in the middle separating the two ways in Water Tanker. The purpose of them is to help with navigation, and to minimize interference in King of Speed.There are no curtains except on the mentioned edges, and we think they are enough to avoid running outside the field area.
King of Speed
- Are teams judged on being able to accelerate and decelerate safely?
This is not an aim for this game, and is thus not part of the scoring. We might update the end zone configuration (balloons area) based on the feedback of the teams, because I’m sure broken boats would make everyone very sad, both team and organizers.
That being said, you are encouraged to take that into consideration so as to not damage your boat so it can compete in latter games. Thoughtfulness in dealing with this problem might get rewarded by the judges as being creative.
- Are the obstacles “freely floating”? Would the boat passing near the obstacles change their position?
Obstacles will (tentatively) be secured by an anchor-like device at the bottom of the pool. They won’t be 100% stable as a result, but we estimate they would be reasonably stable, at least within the +/- 10% range we specified in the rules.
- May you clarify how a crossing gets counted?
This may help:
Figure: Scoring a crossing in Obstacle courseThe “imaginary crossing line” is a line between the centers of two consecutive obstacles/obstacle+roundabout. This illustration shows what’s a valid crossing and what’s not.
- When does this game end?
The game ends after 2 minutes have passed since the start of the round, or the boat leaves the bounds of the field, as per the rules.
- “Note that the 5% range of error applies to the top and bottom of the cup separately – the cup might not be a perfect cylinder, so steps must be taken to accommodate that”. May you clarify this sentence a little bit more?
While the dimensions of the top and bottom of the cup are given as 6cm, they can vary independently by as much as 5%. For example, the bottom of the cup can be as small as 5.7cm and the top as large as 6.3cm, and the ranges also work the other way. This is simply to account for any inaccuracies in fabricating the cups, so you can accommodate it within your holding device.
- What do you mean by saying that the design may not “(…) go along the sides over the top of the cup”?
Please refer to this drawing;
Figure: Validity of designs for holding cupThe third arrangement from the left is invalid because it violates the “goes along the side over the top of the cup” rule. (Note that due to an issue with the drawing some areas of the cup and boat intersect improperly, and it’s not an intention of the illustration.)
