Editorial: Navigation and Perception for Autonomous Surface Vessels [PDF]
Frontiers in Robotics and AI, 2022 While autonomous navigation for ground robots has been studied for a several decades, a large gap is still present for autonomous vehicles in the marine domain. Challenges include unpredictable dynamics, mostly unstructured environments, and comparatively high cost in terms of logistics and vehicles to conduct experiments.

Social Trajectory Planning for Urban Autonomous Surface Vessels [PDF]
IEEE Transactions on Robotics, 2021 In this article, we propose a trajectory planning algorithm that enables autonomous surface vessels to perform socially compliant navigation in a city's canal. The key idea behind the proposed algorithm is to adopt an optimal control formulation in which the deviation of movements of the autonomous vessel from nominal movements of human-operated ...
