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.
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.
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.
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.
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!
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.
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.
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.
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.
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.
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.
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.
@@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.
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.
@ We have a question, how do you not lose traction while carrying the boat of mission 15? We have tried in different ways but we are not succeeding, do you have any possible advice?
@@TeamNextGeneration-FLL Traction is hard to solve. We did few things: 1. If you look carefully we doubled the driving wheel on each side to add traction, that why the wheel is out of robot body, 2. we have to do customized acceleration as the built-in acceleration is not enough, 3. our driving wheel is positioned at middle. P.S. we completely rebuild the robot base for next competition which completely solved the traction problem, we will upload a new video very soon.
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.
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!

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.
that looks amazing! does everything pass the inspection?
Yes, it does!
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.

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.
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.
Just check at 2:16 you may be pushing the shark out of the circle and therefore risk losing those points??
