Separate the robot construction on body - body and attachments. Attachments should be small, light and most importantly for winning the competitions they should be pinless. In this category we group tutorials, courses and materials for different attachments that have proved to be useful.
In this video tutorial, we carry, deliver and drop a large object with an attachment that is much more stable than the basic. We get out of the base, and we actually carry the model. This attachment is also auto-correcting as it has a guiding beam at the front, and even when the robot makes a mistake, we can successfully accomplish the mission.
What if the robot could make a mistake and still accomplish the mission? That is what we demonstrate with this tutorial - a few principles for error tolerance and self-correction. Even though we start the robot from a few different places, we manage to complete the mission with the same program every time. We use the LEGO Education SPIKE Prime robot, and we continue directly after the 10 out of 10 tutorial
In this video tutorial, we demonstrate an attachment that is activated when we reach the mission model. That means the attachment is not activated by a motor but by the movement of the robot. We accomplish the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model, where we have to move and bring cargo to the mission model and leave the cargo there.
This is a 10 out of 10 tutorial where we deliver and drop precisely to complete a FIRST LEGO League 2021-2022 Cargo Connect mission. We reuse the same attachment as in other missions to demonstrate a reusable attachment.
The Load Cargo mission model could be accomplished by loading a cargo in a number of mission models on the FIRST LEGO League 2021-2022 Cargo Connect field. In this video tutorial, we load the cargo on the platooning trucks. In the previous one, we load it on the trains.
In this video tutorial, we demonstrate a reusable attachment. It is the same attachment we've previously used for two other missions. Sometimes we can build such attachments - one attachment that can complete several missions. Yes, the mission is similar - it is Load Cargo, but we are loading the cargo in different places on the field, and that's important.
This is a 10 out of 10 tutorial for a complex robot attachment that does a precise drop and is auto-correcting at the same time. It has decent consistency and reliability. We drop cargo onto the train and use a LEGO Education SPIKE Prime robot for this FIRST LEGO League 2021-2022 competition.
This is a precise drop tutorial where we demonstrate how to accomplish the FIRST LEGO League 2021-2022 Load Cargo mission that requires us to precisely drop a cargo into the drain. It is not an easy task, but it has a trick. A trick that allows us to 'shake' the cargo a little bit. The attachment is also auto-correcting to improve consistency. Use this principle whenever you need to drop things.
This is a 10 out of 10 video tutorial where we demonstrate the consistency and reliability of a LEGO Education SPIKE Prime Active attachment connected to the motors of the robot. The goal of this attachment is to accomplish the Bridge mission where we have to push both parts of the bridge and bring them down to connect them. We use some line following.
In this video tutorial, we accomplish a FIRST LEGO League mission called The Bridge. We demonstrate how to use a really simple active attachment where the goal of the mission is to push down both parts of the bridge. We do not enter into the programming and we leave it up to you as an exercise.
In this 10 out of 10 tutorial, we accomplish the Platooning Trucks from FIRST LEGO League (FLL) 2021-2022. The goal of the mission is to connect the trucks to each other and both of them to the bridge. The attachment and the robot pushes the trucks and we do it 10 times to see the consistency and reliability of the robot.
In this video tutorial, we accomplish the FIRST LEGO League 2021-2022 mission called Platooning Trucks. The goal is to connect the two mission models (trucks) to each other and then connect them both to the bridge. It's quite an interesting mission as it involves three mission models.
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.
This is a 10 out of 10 tutorial on a basic approach for one of the unique challenges in FIRST LEGO League competitions. This basic approach to a solution is not very consistent, and in some of the next tutorials, we will present a new solution. But we decided to record it to demonstrate how reliable this attachment is when it comes to carrying large objects. That could give you ideas of things to avoid.
In this video tutorial, we demonstrate one of the unique missions of the FIRST LEGO League competitions - we must carry a rather large object from base an leave it on the field. This takes some considerations as other missions must be accomplished before that.
This is a 10 out of 10 tutorial, where we demonstrate the consistency and reliability of an attachment activated when we reach the mission model. We do not use a motor. We activate the attachment by pushing the robot to the mission model of the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery Mission.
This is a 10 out of 10 video tutorial demonstrating the consistency and reliability of a configurable attachment. The attachment is designed to accomplish the FIRST LEGO League 2021-2022 Cargo Connect mission model called Sorting Center. The mission model has 3 cargo objects that could be placed in a different way. The attachment is configurable and before the run we configure it for the specific way in which the mission model is set up before the start of the round.
In this video tutorial, we demonstrate a configurable attachment used for accomplishing a FIRST LEGO League 2021-2022 Cargo Connect mission called Sorting Center. The mission model has three cargo objects that are placed randomly. The attachment is configured before the run based on the configuration of the cargo objects. This attachment is also very powerful as it aligns and auto-corrects the errors that the robot is making by squaring the robot.
This is a recording of a completely perfect, 10 out of 10 accomplishment of a two-part mission - Train tracks, from the FIRST LEGO League 2021-2022 Cargo Connect competition. Due to the proper use of motion and color/light sensors, the robot is 100% consistent and reliable for a non-trivial mission. Even when the robot makes a mistake, it auto-corrects and compensates for this mistake.
This tutorial explains the use of motion and light/color sensors to accomplish a complex mission split into three parts. It gets into detail about how we keep a straight line with the motion sensor, follow a line with the color sensors, and transition between different parts of the program by aligning and detecting lines with the sensor. The goal is to get to a reliable and consistent behavior of the robot. On top of that, it is configurable, as we've left a few parameters that could be set to configure the behavior for a specific robot, venue, lighting, battery level, and wheels friction.
"Sometimes it works, sometimes it does not work" - this is the most common case in FIRST LEGO League competitions. In this tutorial, we demonstrate and discuss such a case where the first part of accomplishing the mission always works but the second part has about 60-70% success rate. The robot is not very consistent. Let's take a moment to see it and explain why so that we can resolve the problem in the next lesson.
In this video tutorial, we use the motion sensor and demonstrate 10 out of 10 times how we can keep the robot moving in a straight line. The program is described in the previous tutorial in the lesson where we enter into the programming. Here we visualize how consistent and reliable the behavior of the robot is.
This is a 10 out of 10 tutorial for pushing gently on a mission model. We also discuss how to build robots that tolerate error and auto-correct their behavior.
In this video tutorial, we demonstrate how to gently push an object to accomplish the mission. "Gently" means that we are pushing but not with force. If we push using force, the mission model will fall, and we will not accomplish the mission. We use LEGO Education SPIKE Prime and the Ultrasonic Sensor.
This is a 10 out of 10 tutorial, demonstrating the consistency and reliability of the active attachment for switching the engine in this mission. The power is transferred through a system of gear wheels to a lever at the end. We presume that the robot is already positioned.
This video tutorial demonstrates an attachment that flips a mission model. The mission model is attached to the field, but it contains a lever. This lever must be flipped from one side to the other. There is a switch. We use a pinless active attachment with gear wheels, and you can see how this works in the tutorial. There is no use of sensors as we don't need them. We will leave the alignment and positioning for some other tutorials.
This video tutorial demonstrates the consistency and reliability of the active attachment that pushes the two mission models. The goal is to use both the attachment and the robot to push the mission model and move the truck and the plane after the blue lines.
