Last month I saw the new Lego Mindstorms set in the store. It kind of revived my interest in playing with my NXT set. So I picked a model from nxtprograms.com and started building the forklift with my son. We downloaded the program and installed it on our robot. It worked fine. Of course we soon started improving the model. One of the things I often do is make sure the NXT brick can be removed easily. Somehow most builders tend to fix the brick securely in the robot. But that makes it pretty hard to change the batteries. So with a few minor adjustments we can now simple detach the cables, lift the brick and replace the batteries.
The only thing left to do is improve the program. It is a pretty simple one, that takes quite a few things for granted. We'll need to think of a nice way to improve it. So watch out for more.
