FLL 2021: Deliver large objects - 10 out of 10 on how to accomplish the Large Delivery mission Pro Preview

This is a 10 out of 10 tutorial on an active, auto-correcting, locking, and aligning attachment that accomplishes the FIRST LEGO League 2021-2022 Cargo Connect Large Delivery mission. The difference, as compared to the previous solution to the mission, is that we now use a much more consistent and reliable robot.

In this video tutorial, we will do a ten out of ten tutorial where we demonstrate how we do this large delivery mission. We must deliver this wing, turbine wing and we must place it right there on the field. So we start from base and we must somehow get to the mission model. Let's do it. Ten out of ten.

This here is our run. The robot starts from base, as we discussed in the previous tutorial. It moves,

aligns with the mission model and it leaves the wing and the wing it falls in this first round.

Let's do it again.

We have to load the wing. We've discussed this in the previous tutorial where we enter into the details of how the attachment works and how the programming works. There is a special kind of special locking mechanism for the attachment. The robot moves, it reaches the mission model. There are these guiding beams at the front. They help us align with the mission model. We leave the wing and we are done. We've successfully accomplished the mission. That's quite an interesting mission. And I can't remember a similar mission in recent competitions. Carrying such a large cargo and having to bring it almost to the other end of the field. It's a unique challenge, especially when there are some other mission models on the field. As here we have the truck, the bridge, the large chicken. Third time we start move.

What you can see is that the robot, it is not very precise in reaching the mission model. It reaches the mission model and it makes a slight mistake. There about a centimeter, half an inch, sometimes more, sometimes less. But when it reaches the mission model, it kind of aligns to it. Because of these guiding beams at the front, the robot auto corrects. This means that the robot is much more consistent and reliable for LEGO Education sPIKE prime robots. That's something. It's a general principle. Let's see this run. This run, it also failed two successful out of four runs. But I think that in this run we just haven't loaded it correctly.

Let's run it for a fifth time.

There is a simpler version of this mission that we've recorded. Let's just look at how the road accomplishes this run, aligns and leaves the wing. What I was about to say is that there is a simpler version of this mission with simpler attachment. This simpler attachment, it didn't work well. That's why we decided to build a more consistent and reliable attachment. But the simple attachment is a really neat idea. So I advise you to go and to check it out in the previous lesson, how exactly we accomplish it. For this particular run, we decided to go with rather complex attachment. It has several movements, it has a locking mechanism, it has something to leave the wing at place. This run was also not successful. Three out of three. And because the attachment is complex, what you can see is that sometimes more complex attachments, they become more fragile. There are more moving parts. Because there are more moving parts, there is a greater chance that something will go wrong. And if something goes wrong, we wouldn't be able to accomplish the mission. Six run. Three successful. Three not successful.

Let's see this run. Rotate. Move forward. Align. Unlock. Four out of seven. The principle of attachment is good. There are some issues with the stabilities, but this could be I guess it could be easily fixed if we had more time. For teams that are competing on the FIRST LEGO League competition, they'll probably have much more time to focus on the robot and to improve the different attachments. What you can see this mission is that we are not doing this very often, but we are starting from base. We are starting from base because we want to show how we actually carry the wing.

It was not just an idea to show you how we accomplish the mission of putting the wink right there in the mission model. But it was also important for us to demonstrate how we reach the mission model in this particular mission, because we must carry a rather large load, which is part of the mission. The mission is not only to go there and to leave it, but also to carry it without bumping into any of the other mission models, like the truck or the chicken or the bridge. Five out of eight. Let's see this run here. We saw a demonstration of, okay, the beams at the front, they could align the robot to the mission model. That's true. But if the robot makes too much of an error, a large error, it's impossible for these beams to help you align with the mission model. It's just a large error.

Five out of nine.

Last run.

I hope this is useful, and I hope I see you in the next tutorial.
