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.
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.
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.
Implementing the next logic for aligning to the border when we approach the border from the right.
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.
As an extension to the previous video we talk about the Hi Technic Color Sensor again.
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.
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.
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.
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 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.
Following the previous tutorials from the course, implement the calibration of the minimum and maximum values.
Let's look at what game of life actually is, what are the rules and how to play the game on paper
In this episode of the Basic NXT Programming series I will cover the sound sensor. I will explain how to program the sound sensor, stop on common problems faced, when the sound sensor is used and finally we will build a program that will allow us to control the robot's speed through the volume of the sound.
With this video tutorial, we start with Turns with the VEX EDR robot.
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 I am building the five minute robot from LEGO Mindstorms and I am doing a short introduction on how to make the robot move forward and turn around. Throught this series I will be using mostly NXT-G as a programming environment.
In this tutorial we would introduce you to the concept of loops using this VEX EDR Robot. As a final result we would have a program that makes the robot move in a square and not by repeating the same instructions for move and turn four different times.
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.
The more advanced task is to more in a polygon. This would require calculating the degree of each of the turns and RobotC is a language in which you could implement this math calculation very easily.
In this tutorial, we set the task of implementing another figure with the robot - a triangle.
