Developed by a team at the German Research Center for Artificial Intelligence (DFKI), the Cuttlefish AUV ... (4,921 ft), and can travel in any direction thanks to its eight electric thrusters.

With its current cast acrylic body, the AUV can descend to a maximum depth of 75 m (246 ft). An aluminum body is in the works, though, which should boost that figure much further.

The AUV’s layout is telling. The twin propellers, called screws in nautical circles, are optimized for cruising. So the HSU-001 is likely to be used for long range patrols.
