Thruster failures in unmanned surface vehicles (USVs) can critically compromise mission completion, particularly when severe degradation eliminates controllability in essential degrees of freedom. While traditional fault-tolerant control treats environmental disturbances as impediments to be rejecte…
The visual perception system of unmanned surface vessels (USVs) is often subjected to various adversarial attacks (e.g., lens stains, sun glare, ship painting, etc.), impacting the safety of autonomous navigation in maritime environments. To enhance the reliability and robustness of situational awar
This paper introduces a novel sonar odometry system that estimates the relative spatial transformation between two sonar image frames. Considering the unique challenges, such as low resolution and high noise, of sonar imagery for odometry and Simultaneous Localization and Mapping (SLAM), the propose…
In this paper, we introduce a method to tackle the problem of robot local path planning among pushable objects –an open problem in robotics. In particular, we simultaneously train multiple agents in a physics-based simulation environment, utilizing an Advantage Actor-Critic algorithm coupled with a…
This paper introduces a novel deep learning approach to semantic segmentation of the shoreline environments with a high frames-per-second (fps) performance, making the approach readily applicable to autonomous navigation for Unmanned Surface Vehicles (USV). The proposed ShorelineNet is an efficient…
