Step Counter mission model is one of the more interesting mission models at the FIRST LEGO League 2020 RePlay competition. There is a locking mechanism that does not allow us to just push on the mission model to accomplish it, you must push it really slow and to do this 10 out of 10 times it is challenging.
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.
In this short animation we demonstrate how the LEGO Mindstorms Robot Inventor Distance sensors could be attached to the robot and then use to stop at distance from a wall. This wall could be the border of the field or another mission model. We need an attachment, we need a sensor and we need the robot. In the live video in the lesson we enter into more details and explanations of how the sensor is used. Programs for the distance sensor are provided in the lesson and in the LEGO Mindstorms Robot Inventor Programming course we enter into more details about how to program the distance sensor
10 out of 10 tutorials for the Slide mission was a challenge. There were a lot of glitches with different attachments that we built. At the end we have an attachment that is able to reliably pull the mini figures up, then forward,then down which.
In this video tutorial we accomplish the Boccia mission from the FIRST LEGO League 2020 RePlay competition. We use LEGO Mindstorms Robot Inventor robot. In this mission we use an attachment that does three things in the same time - align, push one lever and drop a couple of boxes in a target. It is a complex attachment and it is worth the watch.
This is a 10 runs tutorial that demonstrates how the accuracy of the robot improves when we use slow acceleration vs fast or default acceleration. Note that the improvement is small. This is not an accurate and consistent robot. No. This is a robot that is all but accurate or consistent. It does not use sensors and you should use sensors. But it is a teaching/demonstration moment for everybody to seen what is it that you can expect if you don't use sensors.
Similar to the tutorial for the LEGO Education SPIKE Prime this tutorial again accomplishes the cell phone mission. The mission is to flip the phone and is part of the FIRST LEGO League 2020 RePlay competition.
In this FIRST LEGO League video tutorial we accomplish the Step Counter mission from the FLL 2020 RePlay mission. The mission model is quite interesting as it can not be pushed fast and it can not be pushed slowly, because it will jam. The robot must push it with the right speed and this proves to be difficult.
This is a true 10 out of 10 video tutorial. The robot accomplishes the Weight Machine mission from the FIRST LEGO League 2021 RePlay competition every single time. The attachment demonstrate a mechanism that performs and is stable on every try
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 discuss probably the most useful principle that we've found for FIRST LEGO League competitions and this is how to align to a line with two color sensors. We use the LEGO Mindstorms Robot Inventor for a quick demonstration of the principle. In the LEGO Mindstorms Robot Inventor Programming course we enter into more details of how exactly we program the sensors. The current tutorial demonstrates the use of such a program and makes clear why this could be very useful and is a must for any well prepared team and wants to achieve a good score on the competition.
The goal of the Innovation project mission is probably to give everybody an easy win on the competition. A mission that does not require an attachment or a complex program and it the same time is quite interesting. In this video tutorial you will see our robot and our innovation project construction, along with how we complete the mission. Hope you like them!
This is a 10 out of 10 video tutorial that is different from the rest. We demonstrate how difficult it is to accomplish a mission and we use an attachment that is working 5 out of 10 times. Our goal with the video is to give everybody the understanding that taking your time to accomplish a mission is the right thing. Most of the 10 out of 10 tutorials at FLLCasts contain solutions and approaches that are working in a repeatable fashion. Not this one. See how difficult it is to accomplish a mission and that we also make mistakes.
This FRIST LEGO League video tutorial is about he Boccia Share mission from FIRST LEGO League 2020 RePlay competition. In the tutorial we demonstrate how to push on a lever to release a mission model part - in this case a box. You have the choice before the competition to cooperate with the other team and to decide if you are going to do the blue or the red box.
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 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.
This is the first video tutorial from our course on LEGO MINDSTORMS Robot Inventor programming. In this tutorial we will start with how do we move without sensors. We will demonstrate a simple program. Our hope with this tutorial is that you will see why moving without sensors is a bad approach.
10 out of 10 for the innovation project mission is quite interesting - move forward, return, move forward, return. In the tutorial you will see how we accomplish the mission every team and how the program is repeatable
In this video tutorial we look at an active attachment that uses gear wheel and the attachment is general enough to be suitable for reuse. This means that a lot of different missions could be accomplished with the same attachment. The goal of the attachment is to transfer power to a lever through a system of axles and gear wheels. It is interesting that we change the orientation of the gear wheels.
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.
This is a 10 out of 10 tutorial where we demonstrate a reproducible completion of a shared mission. The mission is shared as both teams must agree about how they are completing the mission. The tutorials shows the robot approaching the FIRST LEGO League mission model. You will see how the robot pushes on the lever every time for a 10 out of 10 completion.
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.
On every FIRST LEGO League competition and generally robotics competitions with LEGO robots, we build attachments to accomplish missions and we must accomplish the missions in a limited amount of time. Most of the time we can not accomplish the missions with a single attachment and we have to change attachments. This is where building robot attachments that are easy to remove really makes sense. In this tutorial we discuss some of the things that should be considered in the building Easy to Detach modules and attachments
In this video tutorial we use an active attachment with a gears, built only form LEGO Mindstorms Robot Inventor parts, to accomplish the FIRST LEGO League 2020 Treadmill mission. The goal of the mission is to rotate the mission model for a couple of seconds so that a pointer makes a half circle rotation. What you will learn is a good principle to approach such missions.
This is a 10 out of 10 video recording about the FIRST LEGO League 2020 RePlay competition and the mission called Boccia Target. We are using LEGO Mindstroms Robot Inventor. The 10 out of 10 recording shows how reproducible the solution to the mission is. You will see a demonstration of a complex attachment that does 3-4 things at once - it alights, pushes, drops, which are all things that are commonly seen at FLL competitions.
In this video tutorial, we use the Unload Cargo Ship mission from FIRST LEGO League 2021 Cargo Connect robotics competition to demonstrate how we program the robot to keep a straight line while moving. Do we need that for this mission? Probably not, but we do it either way to demonstrate the solution in a fairly simple mission. The program uses the motion sensor to auto-correct the errors the robot is making while moving.
This is a 10 out of 10 tutorial demonstrating the accuracy of an active gear attachment that accomplishes the Treadmill mission from the FIRST LEGO League 2020 RePlay competition. When the robot is well aligned to the line before that it is easy for the robot to accomplish the mission. You will see how we make use of the friction of the wheel to rotate the mission model.
