Abstract
A craft comprises a torque reaction engine, a beam, and a fin secured to the beam. The torque reaction engine causes the beam to oscillate. The fin, secured to the beam, translates through a surrounding thrust fluid as a result of oscillation of the beam. Translation of the fin through the surrounding thrust fluid produces thrust and/or lift on the fin, propelling the beam and torque reaction engine. The craft may further comprise a harness and be a diver propulsion vehicle.
Claims17
A robotic fish comprising a torque reaction engine within a capsule within a dive ring, wherein the capsule relocates within the dive ring to cause the robotic fish to dive and surface, and wherein the capsule is held in place within the dive ring by a pawl.
A robotic fish comprising a torque reaction engine within a capsule within a dive ring, wherein the dive ring is secured to one or more of a nose plate and a tail plate, wherein one of the nose and tail plates are secured to a fin, and wherein ends of the nose and tail plates are secured by cords.
A robotic fish comprising a torque reaction engine within a capsule within a dive ring, wherein the robotic fish further comprises a harness, wherein the harness allows a human to hold the robotic fish.
