A tiny Java Virtual Machine for the Lego MindStorms RCX, containing a VM for Java bytecodes and additional software to load and run Java programs.

Perhaps the best iconic language tool to replace Lego’s RIS, it generates NQC code & facilitates handling the NQC compilation + deployment processes, too. (Project was formerly known as fUNSoftWare.)

An alternative to part of the standard leJOS API designed to fit an objects-early approach to teaching programming

A visual interface for leJOS. RCXDownload automatically sets the JDK-, leJOS- and ClassPaths, compiles the chosen Java-Source, shows the compiler messages and is able to link and load both the compiled classes and the leJOS-firmware.

A Java interface to the Lego MindStorms RCX

An RCX Simulator for LeJOS, based on the earlier Intellego project, for learning to program in Java using the LeJOS platform.

Java Applet GUI for testing josx.platform.rcx.TextLCD

An experimental robot platform API for integrating a Raspberry PI with a Lego MindStorms RCX robot.

A tool for experimenting with robotic control techniques, providing a framework which enables researchers to develop controller programs for the Lego MindStorms RCX in Java, and test them either in simulation or in a real RCX robot with no alteration to the controller code

The leJOS Visual Interface is a skin over the command-line commands for the leJOS firmware. It also is a simple editor that can have many files open at once.

A tangible computer language designed to provide a painless introduction to computer programming, creating programs for robots like the Lego MindStorms RCX (also supports NXT)

A Mirror for repo: https://svn.code.sf.net/p/lejos/rcx/code/ lejos-rcx-code

Eclipse plug-ins that simplify developing Java code for the Lego MindStorms RCX using the leJOS JVM, offering easy configuration through a project wizard and a preference page, using Eclipse code building, and adding RCX-specific operations both for firmware and byte-code download.
