At the competition, we ranked 3rd by the end of the qualifications. We passed through the quarterfinals and semifinals and made it to the finals. We lost to the 1st seed team (4815A) due to us tipping in both matches. Our team was able to still escape with the Excellence Award which qualified us for Worlds. Thank you to 64B and 7503 for excellent alliance partners in the eliminations.
Feel free to give suggestions on how to improve the robot (especially the tipping).
That’s a really impressive lift you guys have. It’s really quick for being geared 1:5. As for the tipping, our team found that putting c-channel on our drive train that extends as far as it could outwards, and as close to the ground as possible really helped with our tipping problems.
We tried doing the thing with the c channel, but it kept getting caught up on sacks as we drove over them. We think that we can program an accelerometer to detect when we begin to tip, and automatically back up to balance us.
