In this project, I will show how to mod the infamous Lego NXT to run the Lejos NXJ firmware, the NXT version of Java. Either version of NXT will work for this project.
In this project, I will show how to put the Lejos NXJ firmware on your NXT and load a simple program. Lejos is simply Java for NXT, so if you know Java, you can easily learn Lejos. Any version of the NXT will work. I will be working on Ubuntu 11.04, but if you are using any other system, it is still easy to figure it out. Good luck!
