About the research project

The applications of AUVs are wider and wider in terms of depth range and dynamic environments, especially under-ice missions, thus require increased autonomy and smart replanning and control algorithms. This project involves developing machine learning based algorithms for complete coverage and path replanning and control of AUVs with numerical simulation and field experiments. Current trend does not show that many intelligent replanning and control algorithms could be verified and validated on real-world AUVs under dynamic changing / challenging underwater environments, especially the effects of unmeasurable ocean currents and in-observable underwater obstacles. The proposed project will focus on the online path replanning and control of the AUV. The proposed algorithm once having been formulated and verified by the numerical solution will be verified and validated onboard a real-world AUV available at AMC.

The main purpose is to solve the problem of online/real-time/in-situ implementation of complete coverage path planning/replanning and trajectory tracking control of AUVs due to the changing environments such as ocean currents and obstacles existing in the transects and regional of interest of mission as well as noisy measurement data from sensors. The target is to formulate the proposed algorithm, and then verify and validate it by both numerical simulation and field experiments using an available real-world AUV under real-world changing environment. The novelty contributions of the project will be depending on the selected method with improved computing algorithms and further developed components in comparison with those in the literature.
