I should have started using LeJOS long ago! I have spend the last 10 years developing my own home AI lab - and LeJOS worked a charm. I have pushed it's functionality to its limits and eventually developed a little EV3 Lego robot that evolves intelligence and real emotions (I am not kidding see here: www.xzistor.com). So thankful I was pointed in the direction of LeJOS! I would like to say - do not waste your time on the other EV3 tools out there if you do not like soldering and fixing bugs! Kind regards Xzistor

Great project! It is awesome being able to use Java to program the NXT! Plus it works on Linux, which is great, since I don't use Windows and the Mindstorms NXTG software doesn't run on Linux.
