Most of the published video tutorials that you could learn from.
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.

Next important state is Turn Right with our robot. This happens when we detect a line on the right.

Based on a request from Abdulah we decided to build a tutorial on how to use Hi Technic Color Sensor and EV3-G Software. There is a special block imported in the software that helps you use the sensor.

After several questions about the use of the LEGO Mindstorms NXT Light Sensor with the EV3 software, we have decided to go through this problem in this video tutorial and pay special attention to the Raw Sensor Value Block.

Next state in our state machine programming pattern is the "Turn Left" state and the corresponding behaviour.
- 02 Mar 2016
We can Turn Right. We can Turn Left. How do we decide which way to go if there are lines both to the left and to the right. Check out the video.

To win the FLL robotics competition you should surely use light sensors for navigating on the field. But the performance of the light sensors is affected by the surrounding light which means you might get different results on the training and on the competition table. This is where calibration is useful. In this video I will show you an easy way to do calibration along with a few examples.

In this episode we do a full run of the mission for collecting a single treasure before going into explanation on how we have programmed the robot.
- 16 Oct 2016
As an extension to the previous video we talk about the Hi Technic Color Sensor again.
- 02 Aug 2015
In this tutorial, we would implement a program that finds the minimum and maximum value detected by the sensor and stores this two values in an array.

All worked as expected, up until know because the robot got lost. This happens when we turn right and the line does not continue to the right. Now the robot must somehow understand that it is "lost" and escape.
- 16 Mar 2016
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.

Let's implement a more advanced program for this robot to learn how to use with motors in opposite directions - and this is to implement the Proportional Line Following algorithm.

Vision is still one of the very few fields where a human being could outsmart a computer. Still. Colour/Light sensors are the cornerstones of implementing a smart LEGO Mindstorms robot that could at least partially do "vision". In this video tutorial, we are using the robotics sensor to detect loading and unloading of the catapult.
- 05 Apr 2015
The final video from the course. The robot escapes the state where it is lost. This happens if it can not continue in any direction.

Many times we just upload blocks and leave it up to you to use it. In this tutorial, I would like to show you how to use the implemented blocks. How to import them into the EV3-G software. How to see them in the palette. How to drag and drop them to build a working program.
- 04 Oct 2017
- 07 Aug 2016
We would continue from the previous program where we used variables and we would change this to arrays.
- 24 Apr 2016
The robot works on the field and decodes the different colours that represent the rows and the columns.
- 17 Apr 2016
- 08 May 2016
We would look at the rules of the competition over our small model and we would start solving the field.

"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
- 04 Oct 2017
In the course section for Advance Sensor Calibration we previously showed you how to find the minimum and maximum value for a single LEGO Mindstorms Color Sensor and to store this value in an array. The program was implemented with the EV3-G software. In this tutorial we are going to find the Min and Max for all the four sensors and to store all the 8 values in an array.
- 04 Oct 2017
In episode 11 we looked at one of the most important topics for the competition - calibrating the light sensors. In this video I would like to show you how to use a more programmatic approach. This means letting the robot do the calibration on its own. Automatically.
