Project Statement

Soft hydraulic actuators have great potential use in underwater robotic applications, specifically, the development and use of a hydraulic fish for exploration, surveillance, recovery efforts, or research purposes. Recent development has produced a soft body robotic fish that mimics body caudal fin locomotion. However, the current prototype is unable to properly swim and dive, while only being able to function at the surface of the water. In addition, the remote communications and autonomous nature of the current underwater fish, although functional, leaves room for improvement. The nature of the application of the fish also required aesthetic qualities that reflect those of a natural fish.

Future development of the project reflects the necessity to improve remote communications, add active buoyancy control, and prevent leakage, while taking into account aesthetic improvements. The capability to move forward and turn in a depth of 3 feet of water is another major priority. These progressions must not influence the success of the utilization of the flexible muscles for propulsion or body caudal fin locomotion. The expected end result is a functional prototype, which can be utilized for the various aforementioned underwater applications, while providing thorough documentation for future endeavors.
