Maybe you have seen my VEX IQ frog at VEX Worlds or on VEX Robotics Facebook and Twitter channel.


My fellow VEX IQ SuperUser Andreas Dreier created building instructions for my robots, I want to share with you here.

The Complete Package for the green and gray version, including the RobotC program, can be downloaded here:

Create, Share, & Teach with SnapCAD

Information about SnapCAD just appeared on the VEX Robotics website. You can now sign up with your email to get informed as soon as SnapCAD is available for download.

So, sign up and while you wait for the download to become available, read the information that is on their official website:

Create, Share, & Teach with One Easy-to-Use Program

SnapCAD is a community-built solution for designing virtual VEX IQ models and creating printable, shareable instructions for them. Use SnapCAD to test out a novel idea in the virtual world before building it physically, or to share your creations with the world in the form of step-by-step build instructions!

Transform your VEX IQ Classroom

SnapCAD is a FREE download and available to anyone with a PC running Windows 95 or newer (see below for full system requirements). Students can even install it on their home computers and bring their models (saved in the lightweight .ldr or .mpd file formats) into class the next day.

A Community Effort

The SnapCAD vision began when some members of the VEX IQ community began converting VEX IQ CAD files into the popular open-source LDraw format. This made them available for use in a number of publicly available LDraw editors.

Built for VEX IQ

Drawing from community expertise, SnapCAD is a new LDraw editor designed specifically for VEX IQ. Students can use SnapCAD to learn the fundamentals of computer aided design (CAD) and create new VEX IQ robots!

  • Comes pre-loaded with the entire VEX IQ part library
  • Supports colored VEX IQ parts
  • Includes pre-built models of the Autopilot, the Clawbot IQ, and V-Rex
  • Adapts to new products ported into SnapCAD soon after public release
  • Creates step-by-step instructions for your custom builds

Legal Download of NXT-G for free!

Here is what Damien Kee wrote on [email protected]:

Great news if you have lost your installation CD or you are looking to
install NXT-G on more computers.

LEGO has just released the NXT-G 2.0 software for download for free.

A few caveats though. This is the retail version of the software so
you won’t have any of the nice graphical datalogging capabilities and
there is no ‚Robot Educator‘ so you don’t have access to all the great
tutorials. The temperature sensor blocks aren’t included but the
colour sensor blocks are. You can always download a temperature block
from Steve Hassenplug’s website

But if all you are doing is standard programming, this will be fine.
I know of one teacher who is happy that they can now load a version of
the software onto their student laptops to take home (previous site
licences were a little murky on take home laptops).

The download is here as well as instructions on how to install it.

Whilst I haven’t tried it myself, I have heard of others being successful.

Experiment „Dockingstation“ / Jeffrey


Some of you already know about it, but now it is official. As a fan of Roberta on Facebook ( you are now able to download an exclusive experiment, describing a dockingstation and a NXT robot, called „Jeffrey“ that is able to find this dockingstation to recharge its battery. Just log in to Facebook, become a fan and click on „For Fans only!“.

Btw, this is the experiment i showed in Zwolle, some of you might remember.

Feel free to blog about it, give feedback and have fun with it!

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.
