How to turn left and right with LEGO MINDSTORMS Robot Inventor
Programming the LEGO MINDSTORMS Robot Inventor for FIRST LEGO League competitions involves learning how to turn left and right with the robot. There are not precise turns. The robot will make mistakes, because that's what robots do. But nevertheless it is important to learn how to program the robot to turn. We are releasing an additional course that is focused only on programming and how to make the robot consistent in its behavior, but in this tutorial we stop on turning

How to use the LEGO MINDSTORMS Robot Inventor Motion/Gyro Sensor
In this video tutorial we demonstrate the behavior of a LEGO Mindstorms Robot Inventor robot when we use the Motion sensor. The Motion sensor was also referred to as Gyro sensor in previous versions of the LEGO Mindstorms Robot. We do not enter into the details of the programming and you can download the programs from the course lesson, but we make a demonstration of how the robot turns to about 95 degrees when we try to turn it to 90 degrees, we explain why and we suggest a way to improve the behavior of the robot.

Animation on how to use the distance sensor from LEGO MINDSTORMS Robot Inventor
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

Animation on how and why to align to a line with two LEGO MINDSTORMS Robot Inventor Color Sensors
This animation demonstrates the principle of aligning to a line with two color sensors and a LEGO Mindstorms Robot Inventor robot. This is a useful concept for FIRST LEGO League competitions where you want to know exactly where you are on the field and to achieve consistent behavior. In the course lesson you will also find a live video tutorial where we enter into more details about aligning. We align the robot to a line by moving both sensors slowly until they both see a black line. When one of them sees the line we move only the other. At the end we return the first sensor back.

How to use the distance sensor from LEGO MINDSTORMS Robot Inventor
In this video tutorial we demonstrate a few ways to use the Distance sensor from the LEGO Mindstorms Robot Inventor on FIRST LEGO League competitions. We don't enter into the details about programming as we do in the LEGO Mindstorms Robot Inventor Programming course, because here we demonstrate the behavior of the robot when the sensor is use and we make the argument that you should always use sensors at FIRST LEGO League competitions

How and why to align to a line with two LEGO MINDSTORMS Robot Inventor Color Sensors
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.

FIRST LEGO League 2020-2021 RePlay Solutions and review with Robot Inventor
This course presents Solutions and Review of the FIRST LEGO League 2021 RePlay competition and it uses LEGO MIndstorms Robot Inventor as a base. It is a mirror course to the LEGO Education SPIKE course for the same competition. For each mission in the competition the course contains the rules for the mission, a tutorial how to accomplish it, instructions for the robot that is used and instructions for the attachment that is used. Every lesson also contains a Scratch and a Python program for accomplishing the mission and of course a 10 out of 10 tutorial that demonstrated how reliable the approach is. Upon completion of the course you will have many new ideas about how to approach mission on every FLL robotics competition and how to help your team score more points.

Robot Accuracy when moving fast VS moving slow on an FLL competition field with LEGO MINDSTORMS Robot Inventor
In this video tutorial we use a LEGO MINDSTORMS Robot inventor robot and we do an experiment and a demonstration with it. We demonstrate what is the difference in the consistency and accuracy of the robot when we move slow and when we move fast. For FLL, WRO competitions there is always this balance between moving fast and moving slow.

10 runs on robot accuracy when moving fast VS moving slow on an FLL Competition field with LEGO MINDSTORMS Robot Inventor
This is a tutorial with 10 runs - 5 of them are slow and 5 of them are fast and we measure how accurate the robot is each time. How consistent is it? Can it arrive consistently on a specific location on the field without the use of the sensors? The quick answer is - No, it can not. But let's see it life

10 runs on improve accuracy by accelerating with LEGO MINDSTORMS Robot Inventor
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.

LEGO MINDSTORMS Robot Inventor Programming for competition with Word Blocks
To successfully advance at competitions we need to understand two concepts - how to reliably and consistently navigate the field and position the robot exactly where we need it to be on every run, and how to build attachments that would accomplish a mission model once we have reached it. This course is focused on the first part. The second part is the whole FLLCasts platform, but start at FIRST LEGO League with LEGO Mindstorms Robot Inventor. "Challenge" competition for 9-16 years old.
The goal of this course is to help you learn to program LEGO Robots using Scratch and make them behave consistently and reliably during competitions. As a language we use LEGO MINDSTORMS App Word Blocks which is based on Scratch. We look at a lot of concepts that could be used for FIRST LEGO League and World Robot Olympiad competitions - for example, how to follow a line fast, slow, in a smooth way, with 5 states. Also, how to align to lines, how to do double align, how to keep a straight line with a motion sensor.
Unfortunately, LEGO discontinued the robot series during the making of this course which is why it's kind of shortish. You could use the SPIKE Prime course for a more in-depth analysis.
