Task: Review our performance at our 3rd League Meet

Today, Iron Reign had its third league meet. It was more successful than our last league meet, with more success with both the drone launcher and our autonomous code. Overall, we went 5-1 and ended up ranked 3rd due to our relatively high tie-breaker points. We ended up perfectly tying with the 2nd place team when it came to autonomous points, and we had a lower score than them for end-game. We saw huge improvements in driving from our previous league meets to this league meet, and learned many valuable lessons about being prepared for matches. However, before we look at some of our takeaways, here’s a brief play-by-play of our matches.

Match 1: 77 - 23 Win

We scored a 45 point auton this round, which is the highest we can score alone. We placed a purple pixel where it was supposed to go, but a bug that started happening with our auton so it could detect placement is that it starts spinning. This can lead to an issue because of how short the autonomous period is, but it wasn’t an issue here. We placed the yellow pixel on its appropriate location on the backdrop and then parked. Driving during the Tele-Op portion started out rocky and we hit the rigging a few times. We were also having issues working together with our alliance partner, as they ended up in front of the backdrop many times as we tried to score and they would be in the wings at the position we needed to be in. One of our wheels was also stuck in a pixel for the majority of the match, which is a problem that could easily have been avoided if we had side shields on the robot. Our alliance team got hung, resulting in our win.

Match 2: 88 - 102 Loss

We got a 28 point auton, where we placed the purple pixel correctly but the yellow pixel was on the wrong section of the backdrop. We also got parking. Our partner was a push bot but they could get the drone as well. We ended up getting a total of 6 pixels on the backdrop by the end of Tele-Op, and we got hang but couldn’t get the drone launched because the drone hit the rigging. Our opponent launched their drone, resulting in their win.

Match 3: 106 - 31 Win

Once again, we got a 28 point auton, where we placed the purple pixel correctly but the yellow pixel was on the wrong section of the backdrop. We also got parking. In this match, none of the other robots had an auton. During Tele-Op, we got a mosaic by placing an additional purple and green pixel. With the help of our alliance partner, Iron Core, we got 6 total pixels on the backdrop by the end of Tele-Op. By the end game, our drone had already fallen off, which was a great missed opportunity for points which remained throughout this entire league meet. The Skyhooks weren’t set up prior to the match, so they were already locked and we couldn’t hang. This showed us how much we need to have a pre-match checklist. We also got 30 points in penalties.

Match 4: 67 - 17 Win

We got a 6 point auton. The purple pixel missed the tape and the yellow pixel fell before it could reach the backdrop. We got parking, however. In Tele-Op, we knocked over the pixel stack so our alliance partner could pick up pixels from the ground. We scored a purple and green pixel in addition to a yellow pixel, resulting in a mosaic. The stage door broke as we went through the center because it was already bent and our robot hit the lowest part, resulting in it bending even further. While we were taking in new pixels, we dropped the drone. At the end of tTele-Op, we had a total of 4 pixels on the backdrop. In the end game, we hung but because our drone dislodged, we couldn’t score the drone. Our alliance partner got parking.

Match 5: 112 - 29 Win

We got a 26 point auton because we scored the purple pixel properly, but the robot dropped the yellow pixel because of the “spin sequence”, which ensures that we are pointing directly at the backdrop but takes too much time. We also got parking. In the Tele-Op portion, we hit the stage door but it didn’t mess us up too badly. Some traffic by the wings also slowed us down. We almost got a mosaic but there was a very small gap between two of the pixels, and all the pixels have to be perfectly touching to be a mosaic. We failed to try for a second mosaic even though there was time. We scored a total of 7 pixels on the backdrop, 1 on the backstage. In the end game, we scored the drone to get a full 30 points and we hung as well! This was our most successful drone launch of the league meet!

Match 6: 85 - 34 Win

We got a 25 point auton, with the purple pixel barely touching the tape. The robot did the “spin sequence” again, but timed out completely so the yellow pixel wasn’t dropped at all. We also got parking. In Tele-Op, we first scored the yellow pixel we couldn’t score because of the weird auton. One of our alliance partners also knocked one of our pixels off the backdrop. Placing one of the pixels resulted in a ricochet so we couldn’t score a mosaic. We had a total of 6 pixels on the backdrop by the end of teleop. In end game, we couldn't score a drone because the drone launcher wasn’t tensioned. This was the second match where we noticed this issue.

We'll be posting another post with our post-mortem thoughts, takeaways, deeper analysis, and some plans for the future.
