Just us being super nervous, four discs went on the floor cuz we drive too fast while getting the blue dispensers😂 Auto even had a higher score...lol

You guys were an inspiration for my team, it’s so sad that you guys didn’t make it. We may not make it to worlds this year either. 😢

Thank you very much for taking inspiration from our robot!! We actually did make into worlds, but we decided that we are not gonna go due to some plans. Thank you for watching this video :)

No so sad you arn't coming tpo worlds. You have a very very good Robot and me and my team got inspired by your first robot. We were hoping we would see you in worlds but stuff hapens. Nice Season GOOD LUCK NEXT YEAR! You are AMAZING!!!!!

Hey! I’m sorry you couldn’t make it to worlds this year. I was hoping to see you at the dome again but, I’d like to understand more on the blue dispenser. I’ve seen many teams do it and even though we won alliance at states in SOCAL me and my team still have a lot to improve. I’ve kinda been scratching my head on why they use the pulleys on the side of the blue dispenser. I’ve read your replies about less tolerance and i don’t understand your term tolerance that well. Can you clarify how it works and what tolerance is?

@PurinChan

Жыл бұрын

The tolerance here means fault tolerance. Which means the ability to endure an allowable amount of variation to the original perfect plan. High tolerance means the robot can still finish the run even if some degree is of. The pulley beside basically guides the robot into the blue dispenser. When the robot is not going perfectly straight into the blue dispenser without the pulley, there is a big chance it is not going in. However, if we have the pulley wheels by the side, it can guide the robot into the dispenser even when the robot is not going in straight. This increases the tolerance of the blue dispenser mechanism.

Question, my team constantly gets discs jammed in the shooter. We have the same plastic tubes you are using, how do you prevent them from jamming?

@PurinChan

Жыл бұрын

The main point to avoid jamming is how the discs fall into the tubes. For example, we are currently using a conveyor belt, and we tried not to make the discs fall straight. If the discs fall straight into the tube, the chance of it getting back is impossible, but if you minimize the chance or make the discs fall only a little tilted, it might solve the problem. Btw, we still have the problem of discs jamming but seldomly.

@PurinChan

Жыл бұрын

Another thing is, the discs often get jammed when more than one discs fall down at the same time. That is why we added a standoff at the end of the tread, this can only let one disc pass at one time. There is a close-up view in this video: kzread.info/dash/bejne/g6OWmrihacbVcaw.html

How do you have enough torque to do the blue dispenser? I made a prototype, but when I put it on my robot, the drivetrain seems to have not enough torque. (I have a 2:1 drive base)

We use a 1.5:1 gear ratio for the chassis. However, I am not sure if this affects the blue dispenser retriever.

We use slow motion to see and record the shooting process, and see if there are some points the discs might get stuck while shooting. This helps us better get hold of the problem.

@PurinChan

Жыл бұрын

@@flyingcheese22608a I personally think the difficulty for the code are the same. However, the main difference will be the tolerance of the robot. If the robot fails a mission by being off by a few degrees, that means the robot still needs improvement. Improvements can include guider for the blue dispenser, or anything that can guide the robot into the correct position. If it is to compare the whole autonomous development progress, I would say pitching in was harder, because there were so many possible strategies that needed to be tried out. For example, which route, where to shoot, how many balls to hold, etc.

woahh our team stand no chance at worlds lol. sorry your team can't make it :( also, has your robot ever had a problem with it drifting, as it's a huge problem for us. if you did, i would appreciate if you could let me know. thanks!

line up for blue and purple its easier to do this than set the exact amount you need to go to line up

@PurinChan

Жыл бұрын

This is to calibrate our gyro for the robot. If we constantly use gyro without re-calibrating it, the degrees are often off by a lot, and it becomes unstable. The borders(walls) are straight so it is an awesome tool for calibrating. Another reason is to make sure the robot always starts in the same position before doing purple and blue.
