EV3 Phi. Teacher's note on negative numbers for Power and Rotations. Minus * Minus = Plus.
In the EV3-G software, you could use negative numbers for power and rotations. In this episode, we would look at what is the meaning of this numbers and make a few notes of where the teacher must be more careful.

How to move specific distance in mm in Mindstorms EV3-G (build a block)
Have you even tried to move the robot not in rotations or degrees or seconds, but in metres. In this episode I am building a new block that could be used to move the robot a specific number of millimetres (mm). You could directly download and use it in your programs.

Gapped and Crossed Line Following with LEGO Mindstorms. Part 1. Challenge. Use of State Machines
We start a course for following a line with crosses and gaps. This is a challenge that one of the users at FLLCasts.com was trying to accomplish and asked us for advice. We present the whole challenge to you step-by-step. But first, let's also see the whole run of the line following algorithm. With this course, we also do an introduction of using State Machine as a programming pattern.

Initialize an array for Advanced Light/Color sensors calibration
"Array initialization" is the first step in every program that involves Arrays. This applies to most programming languages and for EV3-G it is a must.
In this tutorial, we would show you how to initialize the array and how to extract this logic in a new block

Gapped & Crossed Line Following. Part 6. Move after the Gap
We've detected the gap. It's time to move over it. This is difficult because we have to detect where the line is after the 0.1 meters gap on the line following field.

Gapped & Crossed Line Following. Part 11. The state of "Lost"
We discuss the state of "Lost" and the different ways we could escape this state. We also build the next step of our State machine programming pattern where the next state is determined by the previous state.

Extracting the logic for finding minimum an maximum into a new block
One of the smartest things you could do in any software program is to extract logic in small reusable, simple, understandable units. In EV3-G these are called Blocks and we are going to extract the logic for finding a minimum and maximum for each of the sensors in a new block.

Data logging the behavior of the LEGO Mindstorms Robot and its Gyro Sensor
This video tutorial is about understanding the "magic". In this video tutorial, we would conduct an experiment and will look at how exactly does the integral part of the PID algorithm compensate for the error that the LEGO Mindstorms EV3 robot makes.

FLL 2018: How to accomplish M09 (lift heavy) from FIRST LEGO League 2018 Into Orbit. Review
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M09. STRENGTH EXERCISE. I could think for a couple of missions in previous years that require lifting a heavy object. Let's see how this mission could be accomplished.

Crossed lines (T Sections). Positioning. Part 1.
How do you detect a cross-section and move from following the main line to following the crossing line. In this series of video tutorials we are starting with a very simple solution that could work in most of the cases. It is especially useful for the FIRST LEGO League Trash Trek competition where there is such a section.
