RGB LED Strip Controller for LEGO Mindstorms EV3 or NXT

EV3Lights
Some may have seen my article, “Using WS2812B Addressable RGB LED Strips with Arduinos“, back in September? As can be seen in that article, controlling Addressable LEDs is pretty straight forward with a basic knowledge of the I2C protocol. I had planned to cobble together interface to allow RGB LED Strip to be Controller by either a LEGO Mindstorms NXT or EV3 Brick, but my teaching commitments and over projects seemed to have forced the idea onto the back-burner. Thanks to Mindsensor, I have no need to warm up the soldering for the idea as they have come up with a ready assembled interface.

Guide to using the PixyCAM Camera’s EV3-G Blocks

In this article, I attempt to describe the LEGO PixyCAM block, which is used in conjunction with the LEGO Mindstorms EV3 Software. Check out the “Getting Started with the LEGO Mindstorms & the PixyCAM” Article for information on how to install the PixyCAM modules (Blocks) into Mindstorms EV3-G Software.

Getting Started with the LEGO Mindstorms & the PixyCAM

I trust this article will get you up an running quickly with PixyCAM and the LEGO Mindstorms EV3 (NXT). Please make sure you have a LEGO Mindstorms EV3 or NXT brick with a fresh set of batteries. I will endeavor to be as detailed as possible throughout this guide, but it helps if you are somewhat familiar on how to use your LEGO Mindstorms Robotics System.

BrickPi: Raspberry Pi for Mindstorms Robots

BickPi is a system that converts Raspberry Pi into a robot.  The project is a board and case that connects LEGO® Mindstorms Sensors, motors, and parts to turn your credit card size computer into a robot.  The BrickPi allows you to connect up to 3 NXT Motors and 4 Sensors.

Holonomic Platform for 125mm Rotacaster Omniwheels

I’ve been working on a very solid, Holonomic Platform to be used with the large 125mm Rotacaster Omniwheels as part of my display for the TAZ-Brick Collector Club’s Brixhibition to be held on the weekend of 20-21 April 2013.

Wii-NunChuck Controlled Mindstorms NXT Soccer Robot

Wii Soccer Bot
For the forth coming [brixhibition] Exhibition at the end of April, I have been asked to set-up and run a couple of interactive Robot Soccer fields.The Robots needed to be robust and reliable as members of the public will be interacting with them. Also they need to have a a simple, intuitive, and easy to use hand held controller. I have used Sony Playstation PS-2 Controllers, but they have far too many controls that would be unused and confusing to the first time operator. I chose to use a Nintendo Wii® Nun-Chuck Controller for the job.

Want too build awesome robotic contraptions using LEGO Mindstorms NXT motors and sensors and your Arduino Mega? Well now thanks to the boys at Bricktronics, you can with there Bricktronics Megashield Kit.

The Raspberry Pi gets NXTified

Dexter Industries are currently working a LEGO Mindstorms NXT Interface/ Shield for the Raspberry Pi. The Raspberry Pi is a credit-card sized computer that plugs into your HDTV. Add a mouse and a keyboard and you have a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. It was designed to be used by kids all over the world to learn programming. And the Raspberry Pi will set you back a mere $35.00.

LEGO Mindstorms NXT Bin Emptying Robot – Mark III

This is a LEGO Mindstorms NXT “Bin Emptying Robot Mark III”. It is part of a larger project I have been working on, my “Ball Sorting Factory“. A forklift delivers full Bins of balls to be emptied. The Emptied bins are then taken away to the processing facility to be refilled. The Mark II version worked well, but was a little unreliable, unlike this version. Like the previous version, it uses a “Ball Repository” to store, mix and reload the Production Line with Balls when the “Ball Sorting Factory” needs them.

Mindstorms & Arduino, with the OpenElectrons’ NXShield

OpenElectrons (Mindsensors) have released the NXShield which attaches directly to an Arduino. The NXShield allows you to connect NXT motors, NXT Sensors and RC Servo motors, along with I2C devices. Some NXShield versions have headers to connect other Arduino shields on top of the NXShield.

Mindstorms NXT Forklift Truck & Bin Emptying Machine

I’m currently working on a Sorting Factory, complete with LEGO Mindstorms NXT Forklift Truck and Bin Emptying Robot. Part of a larger project I’m currently working on (partly visible in the upper-left corner of photographs). The Forklift is used to deliver full Bins of balls to be emptied by the Bin Emptying Machine, and then the empty bin is taken away, back to the processing facility.

Tweeting Data with NXT2WiFi Webserver Module

In this Tutorial we will go through the steps required to have your LEGO Mindstorms NXT Data sent to Twitter using the NXT2WiFi Miniature Web Server Module. In this Tutorial, the code used to program the LEGO Mindstorms NXT is [nxc]. You will also need a Twitter Account, if you don’t already have one.

Connecting the NXT2WiFi Webserver to a WLAN

The simplest way to connect to the NXT2WiFi Mini-Webserver Module is via an Ad-hoc Network, also called WiFi Direct network where devices communicate only peer to peer (P2P). There is no base and no one gives permission to talk. But this method is limited to the fact you can only have access through a single browser enabled device to the NXT2WiFi at a time. To get around this limitation access to the [NXT2WiFi] via you Wireless Router/Modem is the answer.

NXT2WiFi: Using Webpage Sliders to Control Motors

This tutorial follows on from my previous NXT2WiFi Articles. In this example [robotc] is used to program the NXT. Using Webpage Sliders to Control LEGO Mindstorms NXT Motors with your [NXT2WiFi] is relatively easy. You will need to have the latest [NXT2WiFi] Custom Webserver Source Code in order to use Slide Controls.

RobotC: NXT Beach Buggy Controlled via NXT2WiFi

This LEGO Mindstorms NXT Beach Buggy is controlled via an Internet Browser Interface using a LEGO Mindstorms NXT [NXT2WiFi]. This is my first project using one of Daniele Benedettelli’s [NXT2WiFi]. Any Internet Browser capable device can control it. The NXT2WIFI is a miniature Webserver Module featuring a fully integrated 802.11 b/g/n Wi-Fi interface, giving your LEGO® MINDSTORMS® creations access to any Wi-Fi network.
