YIP: Ultralight, economical and adaptable solutions for deep-sea UUVs and distributed sensing using fiber optic microtethers
Abstract
Accessing the deep ocean for imaging, sensing and sampling is a complex technical endeavor currently requiring the use of work-class ROVs, manned submersibles, or sophisticated autonomous underwater vehicles. These physically large and costly systems restrict access to the deep sea due to their large operational overhead, and impede efforts in high-risk technical development and educational training in underwater robotics.The Undersea Robotics and Imaging Laboratory (URIL) has recently pioneered several deep and cheap technologies that enable low-cost imaging, lighting, actuation, and live-feed high bandwidth telemetry in the deep ocean. These include 3D printed/epoxy-potted camera and computer systems, simplified free-falling lander systems, 3D-printing of pressure housings at sea, 3D-printed soft robotic actuators and hydraulic drive systems, and the recent invention of Fiber Optic Fishing Line (FOFL) and a fiber optic reel system. These efforts have already resulted in several peer-reviewed publications and two filed US patent applications. In parallel, the URIL has been exploring deep-sea fiber optic distributed sensing systems, including novel sensing fiber optics, via support from ONR. While these projects vary in direction and scope they are based on a few core methodologies; heavy usage of 3D printing/rapid prototyping, advanced epoxy-potted and pressure tolerant designs, and innovative fiber optic techniques. The URIL is now a fast-paced deep-sea robotics development laboratory with robust student involvement, with some technologies already licensed into the commercial sector. This Young Investigator Award proposal aims to accomplish two primary goals: 1) the design, development and field demonstration of small form factor aerial (UAV) and surface (ASV) supportable deep-sea mobile exploration systems, and 2) the development of the world s first deep-sea robotics field course for Ocean Engineering and Oceanography students. The first goal is alreadyunderway with the recent demonstration of the fiber optic reel system and associated prototype technology; further support is requested to create mobile, navigable subsea payloads, network hubs, and autonomous/remote deployment platforms, as well as explore its utility for fiber optic distributed sensing and power-over-fiber applications. The second goal will enable the involvement of a larger student population, allowing for multiple designs and methodologies to be explored in parallel, facilitating regular field testing, and supporting the growing need for workforce development in deep-sea robotics.
