29 July 2017 Auckland Scrimmage Summary
In what was our second VEX In The Zone scrimmage here in Auckland, 28 robots turned up to compete and test out their robots at Kristin School. With 49 Qualification Matches, each team got 7 games to play before heading into the Alliance Selection.
The first ranked team at the end of the Qualification Matches was 7682E (Wingus & Dingus), who were the only team to win all their games and one of only two to win 6/7 of their autonomous bonuses. In second place was 2931D closely followed by 2931F (both from Pinehurst School). 2931D had 6 wins and a tie with no autonomous points, and 2931F had 6 wins and a loss, with 20 autonomous points. If the second ranked team (2931D) had lost that game which had been a tie, they would have ended up in 6th position – in this event, every point was crucial.
For the Elimination Games, we saw the blue alliance (lower seeded alliance) beat the red alliance in every playoff except for the case with the 1st seeded alliance, who progressed smoothly into the Finals. Hence, we had a Finals between the 1st seeded alliance (7682E, 2900A) and the 7th seeded alliance (2900G, 2915D). The first seeded alliance won the finals with two convincing wins. Congratulations 7682E (Wingus & Dingus) and 2900A (SymbiOHSis/Onehunga High School)!
Time for some statistics.
At first glance, these match scores look fairly similar to what we saw at the scrimmage on 1st July. The mode of the single alliance scores was still less than or equal to 10 for the Qualification Matches. Overall, scores bumped up a little, but not significantly. The median Qualification Match score was 19 pts for a single alliance, or 42 for the combined score between both alliances. For the Elimination Matches, the median single alliance score was 40 pts, or 83 for the combined score. Once again, we see a major difference between Qualification and Elimination Matches as you would expect, albeit a bit more than ideal.
Once again, at first glance these match score composition charts are almost identical to what we saw at the last scrimmage. Cones are contributing about 25% of the final scores, and mobile goals accounting for about 50% of the score in the Qualification Matches or nearly 60% in the Elimination Matches. We’re still seeing maybe just one highest stack bonus per alliance per match, and about 1 robot parked per alliance at the end of each game (still about 5-7% of the final score though).
As mobile goal scoring is still quite overwhelming for the final score, it’s nice to see where they’re being scored:
Similar to last time, most mobile goals weren’t score in the Qualification Matches, and of the mobile goals that were scored, the 10pt Zone was by far the most popular for the Elimination Matches. Very little was scored in the 20pt Zone, especially for the Qualification Matches.
Looking into the activity regarding cone stacking, we can see how many cones were stacked, and the height of those stacks:
As we’ve already discussed, not many cones were stacked, supported by the chart on the left. On the right, we see that most stacks were short, between 1-3 cones high, and the highest stack was 9 cones tall. There wasn’t too much difference in stack heights between the Qualification and Elimination Matches.
- In only about 24% of Matches was an Autonomous Bonus awarded
- No attempts at the skills challenges
- Highest single alliance match score was 89 points
- Highest combined alliance match score was 150
- Median difference in Qualification Match Scores was 15 points
As always, if there’s something you’re curious to know we’ll try our best to help, although specific robot design questions won’t be answered.
Thanks to all the volunteers who helped out at this event, and especially to those who recorded all of this data for us to share. The standard Tournament Manager exported data doesn’t give us the information to know the heights of each stacks, so we now have an extra scorer recording all the data separately. A big thank you to them for recording so much information. We have grand plans for what else we can do with the data, although how much of that comes to fruition is a different matter – watch this space!
Also, thank you to Kristin School for letting us use their fantastic venue. The next event will be on the 12th August, at Lynfield College.
