Long-Term Autonomy for AUVs Operating Under Uncertainties in Dynamic Marine Environments

RA-L 2021

There has been significant interest in recent years in the utility and implementation of autonomous underwater and surface vehicles (AUVs and ASVs) for persistent surveillance of the ocean. Example studies include the dynamics of physical phenomena, e.g., ocean fronts, temperature and salinity profi

Heterogeneous Multi-Robot System for Exploration and Strategic Water Sampling

ICRA 2018poster

Physical sampling of water for off-site analysis is necessary for many applications like monitoring the quality of drinking water in reservoirs, understanding marine ecosystems, and measuring contamination levels in fresh-water systems. In this paper, the focus is on algorithms for efficient measure…

Predictive motion planning for AUVs subject to strong time-varying currents and forecasting uncertainties

ICRA 2015poster

This paper presents a novel path planning method for minimizing the energy consumption of an autonomous underwater vehicle subjected to time varying ocean disturbances and forecast model uncertainty. The algorithm determines 4-Dimensional path candidates using Nonlinear Robust Model Predictive Contr…

Zig-zag wanderer: Towards adaptive tracking of time-varying coherent structures in the ocean

ICRA 2015poster

Similar to the atmosphere, coherent structures, e.g., fronts, exist in the ocean. These frontal structures are known to be highly productive, supporting the whole spectrum of marine life. Ocean fronts are dynamic in time and space, and are a key component to a comprehensive knowledge of ocean dynami…
