hi,
i am currently working on a project involving the construction of an AUV (autonomous underwater vehicle) for a compt. held by AUVSI.i just wanna know how can i start with it?, can i use phidget sbc and sensors (motion sensors).also i have to interface sonar or hydrophones and image processing is also required.please guide me!

This is not my field, but il throw out some thoughts anyways.

The SBC got the 8/8/8 , ethernet controller and a usb hub on board.
This ables you to hook up a web camera, 8 different sensors, 8 switches a controller for the motors etc.
The ethernet controller can be used to switch the unit into a ROV when needed. (In addition to data transfers when docked of course)

The 1056 could be helpful in navigation with its compass and accelerometer.

Add a usb gps and you are ready to go :)

GPS won't work underwater.

I know that :)
But a unit in a large area could surface to fix its gps location when needed and use the 1056 to calculate positions in between gps fixes.

@persianpatient: I cant see any reason it should not work as on land. Im not familiar with UAVs, but I guess the compass and maybe the gyro could come in handy.

After a bit of research I understand that using the accelerometer for speed calculations presents to many variables to be accurate.
