Continuing with the Proportional algorithm for following lines. Smooth and stable this is the first part of the PID.

Looking at the field we must first think of a strategy of solving this line following problem. There are rules that the robot must follow and these rules should be programmed in the robot. 

Motors can be placed in opposite directions... opposite .. directions. Robo-builders might have difficulties imagining it so we have build one. One of the motors facing forward, the other backward. It is interesting how this robot turns.

After we have introduced a menu in the previous video, this video focuses on storing the values in an array. It presents a basic use of arrays.

Complete introduction to the LEGO Mindstorms EV3 Touch sensors from the very first step. In this video tutorial we program the robot to stop on touch sensor pressed. Again, this is based on your feedback that much of our tutorials in previous years were a little more advanced and that we have never made a proper introduction. A few more videos on touch sensor will follow after this

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

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

In this video we look at the robotics mechanism for dropping the different blocks into the different region on the World Robotics Olympiad 2013 field. 

In a competition environment like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) the color sensor is more than useful. It makes positioning on the field quite easy and precise. 

Very simple and basic introduction to the color sensor in the LEGO Mindstorms EV3 set. The first program is to stop at a line. Then we can move from stoping at line to counting lines and even more complex tasks.

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. 

In this tutorial, I will cover the adjustments of the display and the color lamp blocks from the LEGO Mindstorms NXT-G. Today I will show you how to use the color lamp in order to make your robot more interesting or how to display sensors values or try to draw something on the screen of the brick.

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.

In this episode I would like to show you a way to solve the FLL 2012 Medicine mission using an LEGO Mindstorms NXT Ultrasonic Sensor and a system of gears that converts circular motion to linear.

In this tutorial we introduce the basic algorithm for following a line with one sensor and review the algorithm for quickly followwing a black line with one sensor, implementing both with the Mindstorms EV3 robotics kit.

Display a matrix with "life" and "dead" cells on the EV3 LEGO Mindstorms brick screen. The program is available. You can see it, change it, modify it and learn from it.

We follow a line. We start from the Smooth Proportional Line Following program and modify it a little for this program. We follow the line with the middle sensor attached on port 2. 

An advanced but understandable description of how to program the mindstorm robot to move in a regular n-gon like pentagon, hexagon etc. (Yes, we know math). We have also included notes on the used formulas. A must see for each of you who would like to master the robot movements.

Collect the humans and clear them from the rocket launching region. This is rather straightforward as a task, but it requires a little bit of thinking if you want to do it without manipulators.
