It's also known as a moon fish. I'm thinking a luner lander. The FTC is doing something with weird surfaces. I doubt it will do anything with water. It's got a camera and a high speed router, so you most likely won't be able to see it. I'm guessing the text is in the hint picture because they scanned it out of a book. I doubt there is any info on it that you can't find on internet.
Check out a the trial robots.

I agree that it will be on some crazy surfaces though.
