Hi, I am just wondering if anyone added additional sensors with minimum or no additional microcontrollers to the AR Drone 2. I saw people adding sensors but they also add additional microcontrollers like arduino, wifi etc. I want to add microphone to the drone and use a Teensy microcontroller for this. I don't want to add any additional wifi or communication to this setup. Can I piggy back the microphone data onto Navdata of the drone (say as additional field)?
Connecting the sensor to the drone:
1) Via USB port (need to hack it as it only accepts media devices)
2) Via the 5 pin serial console on the drone motherboard
Getting microphone sensor data to ground station:
1) Piggy back the microphone data onto Navdata of the drone
2) Since the drone runs Linux, can I run additional program in it to send this microphone data to my ground station some how?
I am using the ROS ardrone_autonomy on the client side for accessing the Navdata via wifi.
Will be thankful for any comments, pointers
