In October 2011, I gave a talk with my colleague at Wolfram, Lambert Chao. A recording of the presentation can be seen below.
The talk abstract:
"In this talk we show new Mathematica capabilities for remotely communicating with and controlling the LEGO MINDSTORMS NXT 2.0 robot. We will demonstrate ways to use Mathematica to acquire, process, and visualize sensor data and use that information to control the NXT's behavior."
