In this video tutorial, we accomplish a mission from FIRST LEGO League 2024. We have these Krill and we have a mission called Feed the Whale. We must somehow precisely deliver and drop the Krill. Second mission in the run, there is the Sonar on the left that we have to rotate. We have to do some rotation work there. And this is the goal of the mission. To accomplish the mission, we use the Nautiq box robot, a small box robot, this time with a rather big attachment. We have an attachment that we put on the robot. It's a whole attachment and it does a couple of things and we'll see how it works. The point here is that it's easy to put the attachment on the robot to attach the attachment. It's fast, it's easy, it's pinless and it attaches to the gear wheel. So we have an active attachment. Here is the run. The robot moves, starts from base, feeds the whale, which precisely drops some of the Krill. And rotation work for the sonar. It takes 22 seconds. As always, when we start the robot, it's quite fast. So, we can't see all the small details of how we accomplish the mission. So let's do it slow by hand. This here is the whale. There is a place on the mission model where we can push and this will open the mouth of the whale. So we have this purple beam for pushing and opening the mouth of the whale. Now, when we open the mouth, with opening, the mouth itself will open the container. From the container, the Krill will fall inside the mouth of the whale.
So it's like two motions. First, we push, and then the mouth pushes on the container and opens the container. So what we can learn from this mission is that we can use the mission model to also help us accomplish the mission. Quite cool. Here is how it looks like from a different point of view. A different point of view also for the Sonar. This is an interesting mission because we have to do some rotation work. We have an active attachment and this active attachment is attached with a chain. It's always good to have a chain in your set. It's helpful.
Now, the way we accomplish it is that we have the motor rotate the gear wheel and through the chain, it transfers the motion to a different gear wheel at the end of the attachment. And there is this rotation that we do with a beam at the end of the attachment. So we can experiment with it and we can figure out different ways to build the end of the attachment. The point is that we have this connection with the chain. It's an active attachment we put on top of the robot. It connects with the motor and we accomplish the mission. Here is how it looks when we accomplish it.
I hope this is helpful, and I'll see you in the next tutorial.
