Your hotkey to alternative software development

Essential Reading

There are many nice books out there, but a few of them contain such wisdom that I just must mention them here:

Originally I wrote iRcxCtrl as an API to for controlling the RXC using the infrared tower. That was back in 1998. Recently I revived the code for doing a Robot with a webcam prototype.

iRcxCtrl contains useful abstractions for the controllable parts in your Mindstorms kit such as the Brick itself, the Engines and Sensors, but also a SteerDrive component (two engines combined), Position Guesser, GUI components, a FirmWare uploader (Written because the original CD didn't run on Windows XP...) and a Video capture component. Everything you need :-)

Have a look at the code for a robot that can move, see and guess where it is:
vcr=new VideoCapture(captureDeviceName,resolution,encoding);
LegoIRPort i = new LegoIRPort(rcxTowerCommPort);
PacketFactory pf = new PacketFactory(i);
PacketStreamer ps = new PacketStreamer(i);
engineArray=new MultiModeEngineArray(pf,ps);
drive=new SteerDrive(engineArray,0,2);
guesser=new PositionGuesser(0,2,30);


iRcxCtrl is published under the GPL and can be downloaded as Java source code.
