Using Custom EV3-G MyBlock Icons Images

www.pdf24.org    Send article as PDF   

Introduction

In this tutorial, I will show you how to make custom MyBlock Icons, and MyBlock Parameter Icons. This is very useful because the MyBlock icons allow one to easily recognize in your programs. The tutorial is broken into two parts, MyBlock Icons, and Parameter Icons. You can only use this tutorial with the EV3-G software. The programs only display properly when you install your custom icons in the appropriate directory on your computer.

Before we begin, make a copy of the following directory: “..\LEGO MINDSTORMS Edu EV3\Resources\MyBlocks\images.

FIRST LEGO League Compatible Robot – Mark III

FLL-Robot Mark III - logo
PDF24    Send article as PDF   

This is third in a serious of FIRST LEGO League (FLL) Robot which can be made from a single LEGO Mindstorms EV3 (Home 31313) kit and a handful of other LEGO Technic Parts. It was built with the intention of being demonstration Robot that the team members of the Metal Minds Robotics Team I mentor could build at home with their own EV3 Kits.

This Robot is a development of the Mark II Robot with a number of refinements, and the addition of another Power Take Off point at the rear of the Robot. This later addition allows for two Powered Attachments to mounted on the Robot at one time. Another improvement which greatly improves the Robots Turn and Straight Line accuracy is the replacement of the Jockey Wheels with a pair of  “Angled Ball Joints“.

Preforming the Polygon Shuffle with a EV3 Gyroscope

EV3-G
PDF24    Send article as PDF   

A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. A polygon is any shape made up of straight lines that can be drawn on a flat surface, like a piece of paper. Such shapes include squares, rectangles, triangles and pentagons, but not circles or any other shape that includes a curve.

There are two main types of polygon – regular and irregular. A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides.

Using the TCS230/TCS3200 Color Sensor with an Arduino

TCS3200 Color Sensor Module
www.pdf24.org    Send article as PDF   

In this article I will endeavour to show how to detect colours with an Arduino connected to the TCS230/TCS3200 colour sensor.

The TCS3200 colour sensor can detect a wide variety of colours based on their wavelength. This sensor is specially useful for colour recognition projects such as colour matching, colour sorting, test strip reading and much more.

Powering the LEGO Mindstorms Brick from a 9v Plugpack

en.pdf24.org    Send article as PDF   
I have been asked a number of times too how I power my Stationary and Development Robots from a 9 Volt, 5 Amp D.C. Plugpack connected to the Mains Power Supply. I prefer to have a Power Supply that can easily handle the demands put on it. A minimum rating of 3 Amps is needed if you plan running 4x Motors from the EV3 Brick.

LEGO Mindstorms EV3 Audio Streamed via Bluetooth Audio

PDF24    Send article as PDF   
Whilst displaying my Robots at a major Exhibition, I got to thinking that it would be great to pipe the EV3’s Audio to a Bluetooth Speaker, so my robot can be heard among the noise of a crowd.
Here are my notes so far on getting started with Connecting a LEGO Mindstorms EV3 Brick to a Bluetooth Audio Speaker:

  • Debian jessie is using BlueZ 5 and PluseAudio 5, which are fairly new. There were major breaking changes in these versions, so most stuff you find on the Internet will be for BlueZ 4/PulseAudio 4, so it does not work at all, so watch out.
  • BlueZ 5 dropped support for alsa [1], so the solution for now (until someone updates some bluez-alsa project for BlueZ 5) is to use PulseAudio.
  • PulseAudio 5 only supports the A2DP profile and not HSP/HFP [2] (although it his under development [3]).
