YARB robotic blimp controlled by Google Android G1 phone

The open source Google Android G1 phone seemed like an obvious platform for wireless robotic control, so we created an Android-based console. After running this first with the ground-based Surveyor SRV-1 robot, we made a few small modifications and used it to control the Surveyor YARB. The tilt sensors in the Android phone work quite nicely for rotor control - we have proportional steering so the amount of tilt controls the amount of power, and live video is displayed on the Android screen from the blimp's onboard Surveyor SRV-1 Blackfin camera, carried via the same radio channel that sends the control signals.

The project is hosted on Google Code at code.google.com/p/srv1console/ as well as www.surveyor.com.

Here are some first flight videos -

Sweet! Now just gotta get one of those phones....

I held out for a while on getting a smart phone, but finally took the plunge with Android. I think this will prove to be a good choice because of the open source approach Google has taken and the quality of their development tools.

WOW! that's awesome! great work keep it up.

So this is using 802.11. The JVM is actually fast enough to convert the JPEG's into RGB & blit video using Canvas.drawBitmap. If it was a hobby you could replace the Android stack & run it in C, but obviously to support a business you need to stick with Java. Wonder if the console can run out of the box on a laptop JVM or if it took some Android hacks.

Yes - direct 802.11 or the 3G phone network routed to an 802.11 network.

The Android API is specific to the device, but we have a couple of other Java consoles that you could use as the basis for a laptop console. Take a look at SRV1Test.java or SRV1Console.java. SRV1Test.java is simply compiled with "javac -classpath . SRV1Test.java", and it supports TCP or UDP connections.

Well, since I have the phone , I have a new project.

Excellent article, I personally really like cellular technology, several of my research I have specialized in operating systems of mobile technology and accessories in addition to being part of the organization of Affiliate Programs Directory which is a very important organization in the world technology, this world of software and hardware is great ... thanks for sharing the article!

AWESOME!!!, do you think that i would be able to transmit a video feed from an android device w/ 3G to a server on real time?
Comment by Howard Gordon on November 8, 2009 at 8:23am
Don't know. We're only using Android to receive and using the SRV-1 Blackfin board to transmit via Wifi.
