Hi Goncalo,

We built a 'coastal' type navigation demo using Roomba type robot and
sensors hooked up to a ESD1000 Bluetooth module to offload the computation
to another server.  If you are not too concerned with accuracy it works
quite well. You can see a video demo here:

into the ROS framework yet.

Best regards,
