Field operation of a robotic small waterplane area twin hull boat for shallow‐water bathymetric characterization

Abstract: An innovative robotic boat has been developed for performing bathymetric mapping of very shallow coastal, estuarine, and inland waters. The boat uses a small waterplane area twin hull design to provide natural platform stability for a multibeam sonar payload, and a navigation system automatically guides the boat in a "lawn-mowing" pattern to map a region of interest. Developed in stages over five years as part of a low-cost student design program, the boat is now operational and is being used to generate scien… Show more

“…The desired heading in MOOS is rounded to the nearest degree, and our thruster servo has backlash and stiction. MOOS Trackline performance is consistent with other works that use similar controllers, sensors and update rates [24], [25], and the S-PPC without packet losses is almost as good. The deterioration in performance with 50% packet loss is minor, which is surprising since there are many twelve-second and longer periods with no crosstrack information.…”

“…7). The corresponding point cloud map is shown in the middle (Oct. 10,2013). Over the course of spring the willow tree grew more leaves and the corresponding point clouds became denser, which would have led to a very cluttered map.…”

“…Also, high-end laser rangefinders allowing high scanning frequency can be used [16], increasing significantly the cost of the platform. Finally, the attitude problem can be directly addressed at the design level by implementing passive damping systems [10] or by increasing the size and inertia of the ASV. Such systems can reduce the impact of the main motion frequency, but can hardly be built generic enough to handle the large spectrum of events that an ASV can encounter during a mission.…”

“…The employment of an Unmanned Surface Vehicle (USV) for automatic bathymetry sampling tasks is also presented in [6], furthermore including an adaptive isobath environmental profiles tracking. The autonomous bathymetry task in very shallow coastal, estuarine, and inland water environment is carried out by means of a Small Waterplane Area Twin Hull (SWATH) vehicle, described in [7], which provides natural platform stability for a multibeam sonar payload. In the proposed work, the Charlie USV is employed to automatically execute a set of areacovering missions, for the task of bathymetric characterization of the Loano beach area (Liguria region, Italy), exploiting the consolidated high-level mission control system.…”
