Efficient Optimal Planning in non-FIFO Time-Dependent Flow Fields
James Ju Heon Lee, Chanyeol Yoo, Stuart Anstee +1
We propose an algorithm for solving the time-dependent shortest path problem in flow fields where the FIFO (first-in-first-out) assumption is violated. This problem variant is impo…
Online Estimation of Ocean Current from Sparse GPS Data for Underwater Vehicles
Ki Myung Brian Lee, Chanyeol Yoo, Ben Hollings +3
Underwater robots are subject to position drift due to the effect of ocean currents and the lack of accurate localisation while submerged. We are interested in exploiting such posi…
Streamlines for Motion Planning in Underwater Currents
Kwun Yiu Cadmus To, Ki Myung Brian Lee, Chanyeol Yoo +2
Motion planning for underwater vehicles must consider the effect of ocean currents. We present an efficient method to compute reachability and cost between sample points in samplin…
