Heres the video, LXF and program.
You can customize your robot easily by:
adding a head with an ultrasonic sensor, putting a jedi robe on him (that would be really cool), and whatever you think would make it look cool. If you have 2 NXT's, then you could have battles, you could make an opponent like a battle droid for the jedi to destroy, the possibilities are almost endless.
as you can see in the pictures, I have completely changed my jedi from what it was before. Then it was large, clumsy, and didn't have a big attack range. Now it is compact, sturdy, and has a very large attack range. The new one also is quite a lot easier to build and program.
