Video tutorials

There are a few main challenges with box robots and in the following tutorial we would like to resolve them. Read on and let's see how we could do this. 

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.

It's a box! It's a robot! It's a box robot.  Box robots are very popular on different robotics competitions involving LEGO Mindstorms like the FIRST LEGO League or World Robotics Olympiad. Let's start with a brief introduction and continue in the next videos with explanation on the features of the robot and why such robots are frequently used.

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 video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the Emergency Walk mission 10 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission and this is one of the most difficult missions on FIRST LEGO League competitions ever. 

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.

Here is Lintu. It is a marvelous LEGO Mindstorms EV3 Animal robot that looks like Kiwi, the famous New Zealand bird. It is quite rare to see a Kiwi bird in person. But fear not, we've prepare a robot that looks almost exactly like the original.

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.

Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features. 

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.

Mission

The robot should park in the parking positioned in the north-east corner of the field.

Scores

At the end of the match the robot is completely in the parking area in the north-east corner of the field: 50 points.

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.

With the shape of a box it is very easy to align this robot to different wall and to add very stable pinless attachments to it. The goal of the video is to discuss this feature of this particular robot construction.

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.

The EV3 Gyro sensor is quite powerful, but there are some little tricks when using it. In the previous episode we showed a hardware solution to the problem and now we are exploring how could the sensor be calibrated from the EV3-G software. Thanks to Sharon and Faye (full names omitted) for the request for this video.

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.

The second construction of the series along with a comparison with the first construction. The new robot requires more parts, but has a few more advantages. 

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.

Many teams are having troubles with the EV3 Gyro Sensor and its drift. In this video we are showing one way to fix this behaviour and get an accurate measurement from the sensor. 

Five different robot chassis. This is the goal of the series. To present ideas for different design of the robots and especially the robot bases. If the base is stable and balanced, then in could easily be extended. Let's start with the most simple of the five. 

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 first part we stop at an algorithm that is the base for following lines and explains the basic idea for the proportion. A must watch if you want to understand the robot at its behaviour. At the end the program still wont work so check out Part 2 and Part 3 for the final steps.  

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.

We should how to build a frame that could hold the attachments for specific competition missions. This frame is added in a pinless manner. This means very fast and easy without any glitches of the pins.

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.

In this tutorial we present a way to align your robot to a black line. Go through common difficulties, that the teams face, when they need to align their robot, and provide a solution for them.

In this video we discuss how do we transfer power from the motors that are "inside the robot box" to the gear wheels that are "outside the robot box".
