Finnegan is basically an “agile and aggressively maneuvering biomimetic autonomous underwater vehicle, with oscillating foils.” Video after the break. Click here for first picture in gallery.

The foils allow Finnegan to enjoy a high degree of maneuverability in confined spaces and high speed in open water, which is key for an AUV which will switch between traversing bodies of water and exploring underwater wrecks
