WASHINGTON, D.C. - Inspired by the pectoral fins of reef fish, particularly the bird wrasse, researchers at the U.S. Naval Research Laboratory (NRL) have integrated artificial pectoral fins into a man-portable, autonomous underwater vehicle (AUV) known as the Wrasse-inspired Agile Near-shore Deformable-fin Automaton, or WANDA. Much of the development and testing of the WANDA platforms takes place in NRL’s Laboratory for Autonomous Systems Research (LASR) — a multi-environment facility that can emulate tropical, desert, and littoral conditions on-site. Four side-mounted fins, two forward and two aft, provide all the propulsion and control necessary for the vehicle. WANDA can perform low-speed maneuvers including forward and vertical translation, turn-in-place rotation, and station keeping in the presence of waves.
