NXT Tutorial This tutorial for LEGO Mindstorms NXT is divided in two sections. The “Essentials” are things every NXT programmer should know. Some of these movies have exercises directly under them. It’s important to do these exercises, not just assume you “get it.” The “Advanced” section is for reference purposes. These lessons assume you have a basic robot with two drive motors, a touch sensor and a light sensor.

Nils Völker - Robotics - Spherical Robot This is a ball-shaped "robot" based on a Lego Mindstorms NXT. It moves in any direction by simply rotating the internal mass horizontally and vertically. At the moment it's remote controlled via Bluetooth from a second NXT. So to be precise it's actually not a real robot more kind of a Rolling-Orbital-Bluetooth-Operated-Thing (to make it short: robot). But seriously: It's planned to implement the ability of moving autonomously later on. And to answer the most obvious question right away: No, there is no deeper sense or purpose, but a lot of fun driving it.
Hacking the LEGO NXT If you are a millionaire and able to buy a LEGO Mindstorms NXT, you may find kind of difficult to hack it or create homemade sensors. I believe you already noticed the particular jack that comes with the NXT. It looks like a telephone jack, but the latch is located in one side, making difficult to connect any other cable. That is not a big problem; filling off the latch from a 6-wires telephone connector (RJ-12) may do the job. Once I was able to connect a telephone cable to the NXT, I started to test the signals. Here is what I found: Holding the connector as the picture shows. White wire - Used with the black wire, this pin provides power to the motor.
