Team 240P are proud to present our third robot “High Quality”
8m 5:3 Speed 3.25" Drive
2m 15:1 Speed Flywheel
1m 1:1 Torque Cap Flipper
1m 640RPM Intake
For our third robot, we decided to focus on building an evolution of Medium Quality. This was mainly a new robot purely focused on shooting flags and flipping caps. We came to the conclusion that switching to flywheel was the best option due to the versatility of it, we hope you agree with us after seeing some of what we can do in this reveal . One of the major changes for this robot was switching to a far more powerful 8m drive to help us do what we love, constantly play hard defense on our opponents. High Quality will be competing at the NZ National Championships this weekend, so if you’re interested you can tune in to the stream and watch us lose in RO16. If we qualify for Worlds, our next robot will be called “lossless” (Lossless is a perfect reconstruction of compressed data, so is the maximum quality https://en.wikipedia.org/wiki/Lossless_compression).
Also, we would say flywheel gang, but each launcher is a flower and they’re all beautiful in their own way <3. Don’t be an absolute walnut and rebuild your launcher 2 weeks before a comp because everyone else says that another launcher is “the meta”.
WOW! This robot is proof for why I believe flywheels are the best. Good luck at nationals.
I do have a question about your flywheel’s velocity control, if you don’t mind sharing. How do you accurately control the flywheel’s speed? We’re using a PID loop, but that isn’t getting us accurate results.
Actually, as one of the first people to have seen this robot in person, I can confirm that this robot has been in the works since early November. The robot has been up working beautifully since mid December when I visited, and most definitely isn’t an adaptation of your new year’s robot; the video you linked was published in January.
We use bang bang control, where our hold power is defined as the target RPM target multiplied by a constant. To correct for variation from battery voltage, and to increase accuracy, when the bang bang control is within 100RPM of target, very gentle PI control is added to the output, which is reset when the RPM error goes above or below 100.
