I want this for Christmas.
AQUA 2 is a robot which can swim, dive and move (not very gracefully) on land as well. He looks like a cross between Wall-E and Eva, but equipped with six independently controlled fins that allow him to move in a most peculiar way. So far it has been tested at depths of up to 120 feet.
AQUA 2 has both rear and forward facing video cameras, which are used both to guide it with hand gestures, and for surveying.
It is really cute. The only thing that freaks me out is that these things always end up used for military purposes... Please leave my water Wall-E alone!
