Goal of the project

 Replace the original baseboard with board

designed by Martin Šebek

 Rewrite and extend firmware over the

existing protocol

 Firmware includes

 Wireless sound transmission in high quality  Wireless control of motoric function

(movement)

Already have been done:

 Baseboard created and assembled  Audio transmission in high quality via

Bluetooth

 Application of ADPCM compression

during the sound processing

 Created small programs for testing

partitioned functionality of baseboard
