If you get to a solution that is too complex you should always try to improve it. This is what we are doing here. Arriving at a solution for aligning to the wall that has become too complex.

"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

We explore some common mistakes when a program is developed and becomes complex. We then try to remove part of this complexity. 

We would continue from the previous program where we used variables and we would change this to arrays.

A human being walks with an average speed of about 5 km/h (3 miles/h). In this video tutorial we will develop a block for LEGO MINDSTORMS EV3, that measures the speed of the robot in distance/time units where time will be configurable and could be 1 second or 0.5 seconds or any other number of seconds you pass as a param to the block. Measuring the speed of the robot is very powerful if you start building an Artificial Inteligence for your robot and is quite fun :)

We would look at the rules of the competition over our small model and we would start solving the field.

We are programming this strange construction to move in a square. This is a basic task, but it is worth doing for a robot with motors placed in different directions.

If you look at the properties of the move block and the motor block LEGO Mindstorms NXT, you will see that they have much in common. Still they have several differences. You should be aware of these differences in order to choose the appropriate block for your needs.

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.

Implement a program for stopping at a black line with the blocks containing the implementation details for the InitArray, Calibration and Getting the calibrated result. 

Robotics Game of Life – that’s the name of our new scientific journey. We are organizing a 14-sessions course (1 session weekly). The idea of the course is to develop a solution to the Conway Game of Life where the robots would actually play the game. Students will construct the robots by instructions and lots of imagination. Initial programs will be provided by us and modified by students. 

Once you start turning how to do you a whole 180 degrees turn. The robot almost does it, but not completely

Following the Advance Light/Color sensors calibration for a minimum value for a single sensor tutorial, in this one, we continue with finding the maximum value detected by a sensor and storing this value in an array.

You have the controller, you have the diode. The controller has a number of pins (holes). Where should you put the diode so that it starts blinking? 

The small holes on the controller are called pins. On our controller we have 32 pins. The more pins that you have, the more elements you can controller with this microcontroller. For this video the interesting pins and 13 and GND

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.

In this episode I will show you how to program the touch sensor part of the LEGO Mindstorms education robotics sets. I have given answers to questions like - how the touch sensor works or how you can use it.

As an exercise try to implement the calibration of the minimum and maximum values for a single sensor. 

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

Implement the program for array initialization.

Follow the video tutorials for initializing arrays and implement the program. 

In this tutorial, we connect the Motorola phones to the Tetrix controller using the USB hub.
