In this video we show how to use the gravity sensor of a Apple MacBook Pro in order to remote control a LEGO MINDSTORMS NXT robot. They connect via bluetooth, and the Interactive Geometry Software Cinderella.2 is used as controlling software. It reads the data from the gravity sensor of the MacBook, processes it and then controls the motors of the NXT robot accordingly.

More info about Cinderella at http://cinderella.de, contact: kortenkamp@cinderella.de. Recorded at the University of Education Schwäbisch Gmünd, Germany.

This is my version of the PF Remote sensor made by Dave of NXTPrograms.com

I made this version with a differential input giving one four speed directional output to which I attached a rotation sensor, the rest is programming.

I do not have the RCX style rotation sensors so I used my own optical sensor
It is a simple coloured drum and a light sensor, theres some clever tricks to determine direction but because the sensor relies on full rotations it is a little slow to respond hence the 1 second update (& heartbeat tone)
