Couldn't you do that thing with hazel twigs?


I just checked Adafruit and Sparkfun, neither sells a Hazel Twig breakout board.

With a twig look for snap out board.

GPS --> get current location
[Body of water / river] database stored on SD card or similar. (eg: http://water.epa.gov/scitech/datait/tools/waters/data/downloads.cfm)
Calculate shortest path.

Profit.

Assuming your robot is looking for naturally occurring water, and not just looking for a tap.

So you should know living where you do, how can you tell that the river and lake have not run dry. Ofcourse we could change it to seeking where water was once known to be.

What did the orbiter a few years back use for detecting ice at the lunar poles?
Was it some kind of neutron detector, or just a blunt instrument of crashing one spacecraft and observing the spectrum of the debris cloud with another?

Cosmic rays eject neutrons from the rocky surface.  With no atmosphere on the moon the neutrons can escape into space and be detected.  Water & ice are strong neutron absorbers.   Thus any ice present creates a "shadow" in the neutron scan.

So, you just need a cosmic ray generator.

And a way of removing the atmosphere so the cosmic rays can smash into the ice and not the air molecules.

A Dyson?

Apologies, I thought OP was serious.

Hmm, so some kind of polarized light sensor and GPS could be used to find and seek surface water right?

Now I'm not a seismologist of any kind, but do you guys think that you could possibly detect ground water by using that whatever elastic wave thing-a-majig that people use to search for petroleum.

Can you get a elastic wave thing-a-majig from SparkFun? I need one for my arduino flying carpet project.
Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)

Simply have a bay sea turtle in a little cage on top of the robot.  The turtle will face towards open water.  Now all we need is to sense which way the turtle is pointing.

I can't remember exactly what was that "elastic wave thing-a-majig" called...

Why not buy a seismic reflection sensor. You could probably pick one up at your local Radio Shack!  XD

Good idea, now the question that remains is exactly how is all this to be actually accomplished on the arduino?
