FLL Submerged 3 Solutions to Mission 8
Переглядів 7 тис.2 місяці тому
Here we show three different ways to solve the FLL Submerged Mission 8. Even though the "tornado" is coolest and most innovative, we end up using the solution 3 in the final game, as it's integrated with other missions and no need for a dedicated launch.

There's a simple path to this complex challenge, after many geometry analysis we found it! Introducing "the tornado solution". We are glad to see the tornado solution been used by many teams, following are some examples: ua-cam.com/video/aAxP-AssuaQ/v-deo.htmlsi=J95U2FeTXYgEMg1E ua-cam.com/video/5mdZ78bceZs/v-deo.htmlsi=DmXn1n_A6v2iaQ3- ua-cam.com/video/P_QilHXflQo/v-deo.htmlsi=22NQOb6ISeumv1HG

Bună. Poate cineva să mă ajute cu algoritmul pentru îndeplinirea acestei misiuni? Sunt începător din Republica Moldova și nu îmi reușește. Vă rog mult dacă poate cineva să mă ajute 🙏
Our team posted a tutorial for recreating this. ua-cam.com/video/T1KcoigtMpc/v-deo.htmlsi=-U7IWqAoPcCCxI9-

Can you make a video how to make the robot and extension
Sorry, that might be too much work for our team to do. Also as we keep improving the robot, the design keep changing, we no longer have the robot in the video anymore, a much better one is here and we plan to release a new video in few days.
Very smart solutions, and thank you for the details in various comments. Hope you got selected to National. Do you use PID controller to drive straight and turn? What max speed do you run for straight? Is it 50%. Can you please provide the Lego model number for the black wheels? Do you use the casters for the front wheel or anything else? Thank you.
Thanks! We do use PID for move straight, but not for turning. Most of our moves are 100% speed, with customized acceleration and deceleration. That's how we got it move accurately. The black tire is in set of 51515, but it's identical to the one in the spike prime set (just color difference). We do use 2 tires on each side (total 4 tires) to increase traction. We do NOT use casters but a simple supporting wheel.
@@NGEngineers Thank you very much for the expeditious reply. Cheers.
Is it possible to provide a picture of an example of the acceleration and deceleration code in the community tab of your channel? We are having a hard time finding good explanations and how to implement these 2 concepts in driving straight and during turns. Or do you have a video explaining the same. Thank you.
I really like your design and your detailed answers to each question in comments! Your sharing inspired my team and thank you!
Awesome! Thanks for the support!
hey I have questions for quests and how did you build the extensions can you help?
Sure, any specific questions? You can ask here, we will reply.
@@NGEngineers can you send me the spike program file of the mission we can see in the video?
@ we don't use spike prime, but 51515 which makes sharing code hard.
@NGEngineers hmmm try doing a video about the coding please?
amazing attatchment man. very impressed
Thanks
how does the first one stand up until needed
It connected to the mission motor, and as long as mission motor hold the position it will stay upright.
at 2:00, are you allowed to put the pieces by hand to the boat? I thought you have to do that by using the robot.
You can use your hand as long as it's in your home area. That's why we use robot to grab the boat back.
Works great thanks!
Great to hear!
Can you share the code?
Since each robot is different the code is not helping much.
I would like to see it..Can you share?
Hello, how are you? I'm from a team here in Brazil, and I'd like to ask for help with your schedules, in the curves and straights! If you could share, it would be great!
Do you have specific questions? We could answer here.
my team actually used the 2nd one, and is really effective if you get the operands perfectly tuned
Yes, that's the fastest solution by itself :)
Do you have tips on how to use the color sensor to make the robot move consistent?
We don't use the color sensor at all. It's not necessary for this year's map, and in our experience the color sensor is slow and not very reliable due to different site has very different light setup.
@ Ok, also do you guys clean your robot and wheels consistently? I want to know for my team
@@gamingbro-nd4wk Yes, we do clean the wheel all the time.
Hello, My name is Dylan, I am a member of Cloverbots 48816. I just wanted to pick your brain a little bit. Your turning and speed control look really accurate and consistent to me, how is it that you do this? When we run our robot something always goes wrong in one way or another with the robot being off target. How consistent really are these runs? Did this video take multiple takes to get perfect runs? Do you use 3rd party software? (PyBricks, ROBOTC, etc.) Answers to these questions would be great, hope you're having a good day! Thanks!
Hi Dylan, for the turning accuracy, we use gyro and customized declaration, we also tested the turning in different speed and find the most consistency result in each case. You also need to be aware of accumulated error, we try our best to reduce the number of turns for one run, and always try to use mission to realign the robot. Our robot run pretty consistent, in our normal practice we always get more than 550 points. We are still improving the consistency. The video did take multiple takes, mostly due to our camera shooting skills not the robot :) We didn't use and 3rd party software, all our code is word block.
great!
Thanks
Buildinginstructions plz
Sorry, we don't provide build instruction as we keep improving and change it.
Aww
How do you keep the claw that lifts shipping lane change so perfectly flat and level throughout?
We use a parallelogram shape, that way the claw always parallel with the ground.
How to make
Sorry, we don't provide build instruction as we keep improving and change it.
Hello, I don't understand how your run 4 can get the treasure out of the location, because it is blocked by the curved red lid, what do you use to open it, I did the same thing in the video but I can't open it.
Your mission setup might be wrong. The claw ("curved red lid") should be landed on top of gray bar. When the ship mast been raised the claw open a little bit automatically then will close quickly as it drop from gray bar, that's your opportunity to grab the treasure chest.
@NGEngineers can i contact to you ? Facebook or mail or Telegram?
@@NGEngineersCan you point to where this is documented? Our team would like to take advantage of this but don't want to risk it unless we can clearly point out clear documentation to referees.
Check the official's setup video here: ua-cam.com/video/Kk8jnsBgl9o/v-deo.html Around 4:10
@@NGEngineers can i contact to you?
How does the coral tree stay in it's holder? Isn't the coral tree designed so that it cannot be directly lifted upwards?
It can be lifted directly, you just need to find right geometry. We just raise the turning point 3 stud above the ground.
Sho
Thanks
Sho
Thanks
tutor please
Sorry, we cannot provide detailed instructions to replicate the robot, as we continue improve it :), but we hope the principle and solutions can help you.
that looks amazing! does everything pass the inspection?
Yes, it does!
But pls share the building instructions
Each robot is different, our attachment can only work with our robot design, so a detailed building instruction may mean nothing to you. However we will provide a video to explain how this works.
@LightingGameing-s6k Check our building tips here: ua-cam.com/video/T1KcoigtMpc/v-deo.htmlsi=9Y7DpHgWe_yDsVFF
Impressive
Thanks.
2nd solution good andres aprovered
Thanks
What keeps the krill holder held up until the right time on the mast raising attachment? I see there's a locking piece that gets pushed up by the mast crossbar, but I can't quite tell how it is able to keep the krill holder in place.
There's a axle that steak into the arm's pin hole, when the tigger was touched the axle moved up to free the arm, check out the 1:12 in the video, looking the light gray part.
@@NGEngineers Thank you for the answer!
this video dosent follow the rules of the compitition
Anything wrong you can point out?
does this video obey the rules of the competition?
Absolutely!
last attachment=s*** and f***
In Run 5, how is it that the Trident grabbing hook doesn't fall forwards early? I can't see what makes the holder in the middle strong enough to not slip before bumping into the trident area.
The grabbing hook is hold by a trigger at bottom (two yellow axles, two gray connector, and two black half beam), and only released when it hit the mission. If you look carefully, at begin of run 5, our operator has to lift up a safety lock, it also prevent us to miss trigger the release.
It's just that to some pieces that I can't decipher how to make it, would you send me other photos on each side of the accessory, please, and to I can't decipher its gear combination. I think it would be fine if you passed and it is possible to have images of the accessory alone as well as an image of its bottom part, please, if you can, maybe the rest has the same difficulty. Do you have Discord,Twitter or Instagram?
We plan to release more pictures in the "Community" tab of this channel later. Trying to recreate the whole solution from pictures usually very hard, since there's many details and each robot is different, we found the best way is to learn the principle and method and try to adopt it into your own design. Hope this tip can help you.
Can you help me with Run 3?
Sure, we have posted few pictures in the "Community" tab of channel, let us know if you have specific questions.
Could you maby give me a tip on how to built something like what you built to solve feeding the whale mission
Sure, for the feed the whale mission we first figured out the overall structure: one krill holder on top of whale and one push stick at bottom to open the mouse, once that determined the hardest part is to figure out a tigger and release mechanism to dump the krills, we use the whale mouse as a level to push a small trigger under the krill holder, the trigger then release the trap door that hold krills in the container. Hope this can help you.
Just check at 2:16 you may be pushing the shark out of the circle and therefore risk losing those points??
Good eye, the shark's fin is raised upward by accident, if it's flat then we shouldn't push it far. We also can leverage a free precision token to grab the robot after the mission ship and crab mission is done, not idea plan but in case something wrong that's can save us points and time.
nice job
Thanks!
please
We plan to release some images in the channels "Community" tab. Stay turned :)
Hey, I really like your idea is very nice. Is it possible for you to send me a image double the accessory used in round 3 either by discord,twitter,email please if you want something in return be made thumbnails for you tuber i show you what it is Please People pay me 14 dollars for each thumbnails but I would give them to you for free please help me I don't like to talk about it here you pass me your discord or your twitter and there are talks
We plan to release some images in the channels "Community" tab. Stay turned :)
@@NGEngineers Ok, thank you very much but can you find a way for me to pass some images either through discord, twitter or Correa electrónico 0:52
Wow! Great video!!!
Thanks!!
Good concepts... 👍
Thank you 🙂
The 3rd solution is really awsome, not oversized and get the job done well!!
Thanks! It takes us many tries to make it right.
Excellent. Could you please share the details of coral nursery mission? Or a close up of the attachment?
Thanks! Our robot base has a built-in gear box, that transfer left mission motor's power to both front end back gears. In the coral nursery mission, we use left mission gear to push the level, the front mission gears to lift the tree and release the shark, then we use right mission motor and gear to pickup the diver, all this happened at same time.
