Box Robot for Robotics Competitions. Requirements for additional parts
This video discusses the fact the robot requires a few more parts that are available in the LEGO Mindstorms EV3 robotics sets. We have a number of other constructions that require less parts, but for this particular robot construction we have decided to go beyond the standard sets, cheaply buy a few more parts and build a whole box robot with them.

FLL 2021: Gently push - How to accomplish the Accident Avoidance mission
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.

Reusable geared active attachment for changing LEGO gears orientation
In this episode we build a reusable attachment for a LEGO Mindstorms EV3 robot that changes gears orientation and direction. It is one of the most useful attachments that you could use to move levers up/down and right/left. Adding the attachment on the robot takes 2-3 seconds and shows a very useful general principle of how to build reusable attachments.

EV3 basics course. Gyro Sensor. Mounting the sensor vertically (part 4)
The Gyro sensor can be positioned horizontally, vertically or at a random angle. Have you ever wonder what does the gyro detect when it is positioned vertically. This is the subject of this video tutorial for the LEGO Mindstorms EV3 Gyro Sensor.

How to use Motion Sensor to accurately move forward with LEGO MINDSTORMS Robot Inventor
With this first tutorial on the Motion Sensor in the LEGO MINDSTORMS Robot Inventor course we demonstrate the basic algorithm for moving in a straight line with the Motion Sensor. From here all the other algorithms are modifications, and if you know the basic it will be easier to tweak the behavior for your particular challenge

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.

Quick Pinless Attachments for LEGO EV3 Competition Robots (Part 2)
If you think that the quick pinless attachments shown in video 63 are quick enough, see this tutorial and you will find out that the quick pinless attachments could be even quicker. These attachments can work without motors but by using the inertia forces.

Accelerate and Decelerate with LEGO MINDSTORMS Robot Inventor
In this video tutorial we are demonstrating the impact of slow and fast acceleration on the robot. In the Scratch program there is an acceleration block for fast and slow acceleration. The robot behaves in different way. Let's explore them so that you know what to use for FIRST LEGO League competitions.

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

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.

FLL 2021: Flip a switch - 10 out of 10 on how to accomplish the Switch Engine mission
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.

Constructing LEGO Mindstorms EV3 Competition Robot - the Process
In Episode 58 we introduced you to a LEGO Mindstorms EV3 Modular robot. In this tutorial, we show you how we reached that construction. We start from a construction found on the Internet and take you through the process of examining and improving it, till we reach a more stable and reliable robot.

FLL 2021: Flip a switch - How to accomplish the Switch Engine mission
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.

FLL 2021: Push with an attachment - How to accomplish the Transportation Journey mission
In this video tutorial, we push two of the mission models with a pinless active attachment with gears. The goal is to push the mission models after the blue lines. This attachment is interesting as it demonstrates a non-straightforward idea of how we can push the mission models. We explain the Scratch program and how we use the motion sensors - you will learn how to turn to a specific angle by using the motion sensor.
