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.

RobertaSim – LEGO Mindstorms RCX Simulator – Free Download for Roberta Teachers

http://roberta-home.de/sites/default/files/images/Roberta-Sim.artikelbild.JPG
From now on the LEGO Mindstorms RCX Simulator – RobertaSim – is ready for download for all certified and registered Roberta Teachers on the internal pages of the Roberta portal.

RobertaSim can be used to simulate LEGO Mindstorms robots (of the Robotics Invention System 2.0 series). The software enables the user to program a virtual robot with the usual programming languages (RIS/RCX code and NQC). The behavior of the real robot to be expected can be observed in real time on the monitor. The virtual robot’s operation has been adapted from the one of the real robot.

Balancing Roberta-Robot

The program code for the balancing Roberta robot „Philippe Petit“ is now available for download at the Roberta-Homepage. The download is available for all Roberta Teachers at the internal download section. Videos are available at the Roberta Youtube-Channel.

Free German NXC Tutorial

Not eXactly C is a high-level programming language for the Lego Mindstorms NXT. NXC, which is short for Not eXactly C, is based on Next Byte Codes, an assembly language. NXC has a syntax like C.

There is a new version of the NXC Tutorial available at the Roberta Homepage. It is an extended german version of the tutorial original based on the work of Daniele Benedettelli.

You can download the german tutorial for free here: http://roberta-home.de/de/was-bietet-roberta/roberta-reihe/nxc-tutorial
