We progressed in different fields today.
Alain designed a small extension PCB for the beagleboard. This board will include the necessary elements for audio amplification in and out, and for level shifting between the beagleboard’s output and the motors’ input.
At the same time, we worked with Thomas to build a first tracking system demo, by placing the webcam on top of casper’s body, connecting it to the beagleboard and then connecting the serial link to drive the motors. This demo gave some first results tonight, and will be kept under improvement.
Finally, we managed to create a custom language model and dictionary, which combined with the pocketsphinx engine’s data now allow the beagleboard to understand french vocal commands.
