EV3 Sensor Adapter for NXT or Arduino

I just stumbled across the following on the mindsensors.com products:

EV3 Sensor Adapter for NXT or Arduino


Using this adapter, you can attach new EV3 sensors to your NXT or Arduino.
(This is basically a UART to I2C adapter).

  • For NXT, works with BricxCC, and new EV3 IDE for NXT
  • Lightweight and small design, that fits in-line with your sensor and brick
  • Use with Arduino with NXShield


I will test this adapter in the near future and write more about it here. Because the adapter is not supporting NXT-G, but the new EV3 IDE together with the NXT brick, this will then also be my first time using the new software with the „old“ NXT hardware.

Infos from TheNxtStep (Author: Daniele Benedettelli):

MINDSENSORS has designed this shield that will allow Arduino to replace *ehm* to be integrated into the LEGO MINDSTORMS system.

It will have 4 NXT motor ports, 4 NXT sensor ports and several RC servo motor ports. The NXShield will attach to an Arduino Duemilanove or Uno or similar Arduino clones. (Picture shown here with a Duemilanove)
The programming for the NXShield will be on Arduino, using usual Arduino C/C++ programming environment. There will be only one I2C port, so you can use multiple sensors on the bus only if they have different addresses.

Roberta-Dokument – Hardware des LEGO Mindstorms NXT Systems

Das Roberta-Thema „Hardware des LEGO Mindstorms NXT Systems“ behandelt die Hardwarespezifikation und Hardwareevaluation verschiedener Sensoren für das LEGO Mindstorms-System. Um Kenntnisse über die Genauigkeit und Zuverlässigkeit der Sensoren und Motoren und deren Zusammenspiel mit dem NXT-Baustein zu erhalten wurden zunächst die Hardware des NXT und verschiedener Sensoren spezifiziert.

Anschließend wurden Testreihen mit folgenden Sensoren durchgeführt:

* Tastsensor
* Geräuschsensor
* Lichtsensor
* Ultraschallsensor
* Kompasssensor
* Infrarotsensor
* Beschleunigungssensor

Das Dokument steht zum kostenlosen Download auf dem Roberta-Portal zur Verfügung.

The LEGO MINDSTORMS NXT 2.0 Discovery Book —New from No Starch Press

A Beginner’s Guide to LEGO MINDSTORMS NXT 2.0

San Francisco, CA, April 22, 2010—The LEGO® MINDSTORMS® NXT 2.0 set brings robot building to a wide range of hobbyists. But the NXT kit doesn’t come with a how-to guide and it only includes building instructions for four robots. Users new to building complex LEGO models or lacking experience with the NXT programming language need guidance to help them reach the next level. The LEGO MINDSTORMS NXT 2.0 Discovery Book is the introductory book that they’ve been waiting for.

In The LEGO MINDSTORMS NXT 2.0 Discovery Book (No Starch Press, May 2010, 320 pp., $29.95, ISBN 9781593272111), readers learn how to harness the capabilities of the NXT 2.0 set to build and program their own robots. Author Laurens Valk begins by walking readers through the set, describing the pieces and explaining how to get started with the software used to program NXT robots. Once readers understand the basics of the NXT programming language, the book’s tutorials show them how to build robots that move, monitor sensors, and use advanced programming techniques like data wires and variables. With crystal clear, step-by-step instructions, readers will find it easy to create working robots in no time. The LEGO MINDSTORMS NXT 2.0 Discovery Book features:

  • A complete introduction to LEGO MINDSTORMS NXT 2.0
  • Building and programming instructions for eight innovative robots, including a robotic defense system, a six-legged walker, and an autonomous robotic arm
  • 50 sample programs and 72 programming challenges (ranging from easy to hard) that encourage readers to explore newly learned programming skills
  • 15 building challenges that expand on the robot designs to help readers develop ideas for new robots

All of the robots in the book require just one NXT 2.0 set to build; there are no extra pieces required.

„The NXT set can be complicated. Sure, you can build some sort of robot, but can you actually make it do anything interesting?“ said No Starch Press founder Bill Pollock. „This is the introductory MINDSTORMS 2.0 book that everyone needs; the one book that will make sure that that pricey MINDSTORMS kit won’t end up gathering dust in a shoebox somewhere.“
