Starting leJOS might be very problematic, since you need to install a few libraries and make some configurations. In this video tutorial I am showing a step-by-step guide on how you could install leJOS on your Ubuntu Linux. And it is quite easy.
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 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.
In this video we are solving Senior Solutions missions: Stove, Gardening, Similarity recognition, Ball game and Wood Working. We will make step-by-step of everything we do on the FLL field.
In this video tutorial I give a step-by-step explanation of how to implement a block for aligning to a line. The block was first used in lesson 28. Aligning to lines is probably the most powerfull way to know the position of the robot on the FLL Competition field and to be able to execute the missions precisely at 100% of the time.
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.
In this episode we are showing the great similiarity between the sensors in NXT Mindstorms. We are solving a common problem - How to make a robot that do not fall from the table. We are using the Ultrasonic sensor, Light Sensor and Touch Sensor to solve the same problem, but with three different sensors.
In this video lesson I will show you how to follow a black line using just one sensor, but fast enough so that you could use it during any robotics competition without wasting any time.
In this tutorial we will go through a solution for three of the missions from 2012 FIRST LEGO League competition using only one attachment. By accomplishing the medicines, strength exercise and cardiovascular missions we earn 55 points. You can download the programs from the link in the Materials tab.
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.
There is no block for programming the Ultrasonic Sensor in the retail version of the LEGO Mindstorms EV3 software. In this video tutorial we will show you how you can download & import such blocks in order to 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.
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.
This video lesson shows a very interesting specific example on how to use the LEGO Mindstorms EV3 Ultrasonic Sensor. The sensor detects if the catapult is loaded or if we have just fired an element. At the end of the lesson I also offer an interesting challenge that you could use in your classroom or at home.
This video lesson is a revised version of Episode #1. Matt Gipson requested it in a comment. Using the EV3-G software we have developed a very simple program for following a line with two LEGO MINDSTORMS color/light sensors.
