I hinted that the DIY Drones team had been working with Google on an Android-compatible RC interface board. Now that I/O is over, I can give the details. We're calling it the "PhoneDrone board for Android", and it's a way to connect any Android device (2.3.4 or higher) to the world of RC and UAVs.The board has 8 channels of RC in and out, with PWM-to-PPM conversion and multiplexing between RC and Android control. You just plug the Android's phone USB connector into the board and you have two-way communications with RC gear and any other board, such as APM.


That means that you can switch between RC control and Android control or mix the two. An example would be "fly/drive by wire". You steer your vehicle via RC, but an Android phone does the actual control using its onboard IMU. On a car, that would allow every turn to be a high-speed controlled drift, for instance (we may show something like that at Maker Faire).


Or, with a UAV, you might have the Android phone doing high-level image processing and object tracking, sending mission commands to an autopilot board such as APM. You might also want to use the phone's long-distance wireless instead of an Xbee for two-way telemetry.


This can either replace APM if you've got equivalent code running on Android, or compliment it with the Android device doing image processing or long-distance wireless comms.


Note that the pictures here are of an early prototype and some branding has been photoshopped out, pending final silkscreen approval.

  • Hi all. I wanted to do what sounds like the opposite of many people here. I would like to take the ArduIMU V3's output (or another sensor board with gyro, accel and compass) and use it to replace the crappy sensors in an Android handset. This is so that the phone can play games and do AR accurately. I was thinking about an IOIO and the IMU but I am very much a learner here and my knowledge is still very basic. Any advice?


    Hello there, I just got my PhoneDrone board and couldn´t find any documentation yet. I created a google group and invite you all to join. Maybe some of the diydrones/3dRobotics people join as well ans support us.

    If you have any suggestions, contact me in the group.

    Cheers from Berlin

  • the board plugs into an android phone. android phones usually have the sensors such as giro,accel,mag,gps so think of the phone as the oilpan or intelligent imu and this board as the apm. There are other uses for this type of board (see other google IOIO devices) but this is a simple answer.

  • Ok in this case what is exactly the goal of the PhoneDrone board :

    - without ArduIMU we can't use it as the ArduPilotMega or we must use the Android ebbbedded IMU ? If we want use Android video for motion trackin, is it a good idea to use the Android IMU for drone attitude and read it 5, 10 or 25 ms???

    - Connected to the ArduPilotMega what is the utility of the 8 PPM IOs?

    Guillaume: I'm afraid not. They are all very different boards. It's probably possible to wire together an ArduIMU and PhoneDrone board somehow and have the combination serve as an autopilot, but you'd have to heavily modify the ArduPlane code. I don't believe anyone else has done that, so you'd be on your own.

  • hello i have a question about the PhoneDrone : is it fully compatible with the ArduPilotMega board?

    I explain : before i wanted an ArduPilotMega and an ArduIMU for my drone... In a first time can i use the PhoneDrone with ArduIMU without Android phone? Can i plug the ArduIMU on the PhoneDrone like the APM?

    And use the same firmware as the APM?

  • Anyone have any luck getting and android accessory kit DemoKit to run on anything other than a Nexus?

    I'm battling with a Samsung Tab and a t-mobile G2, both of which are supposed to work, they have Android 2.3.4.

    I have the latest Android ide and everything is up to date...

    I keep getting this:


    Package com.google.android.DemoKit requires unavailable shared library

    accessory; failing!
  • I picked up one of these boards at Maker Faire a little while ago, and I haven't been able to find any information whatsoever on it yet.  Does anybody have a pointer to any resources on the board?  I'd be happy even with an archive of the mailing list used by the developers when they were putting it together.
  • Any updates on when this thing will be available? Anything at all? The store page still hasn't been updated in 2 weeks :( I want it.
  • Great Board and great work I am going to assign one of my student to write autopilot code for Google Android handset that include everything to become a full autopilot as his final year project. The Handset which he will use is Android IDEOS. It has built in GPS, Accelerometer and Gyros......
