ROV Navigation in a Fish Cage with Laser-Camera Triangulation
Aquaculture net cage inspection and maintenance is a central issue in fish farming. Inspection using autonomous underwater vehicles is a promising solution. This paper proposes laser-camera triangulation for pose estimation to enable autonomous net following for an autonomous vehicle. The laser...
PSO and Kalman Filter-Based Node Motion Prediction for Data Collection from Ocean Wireless Sensors Network with UAV
Safe navigation in a coastal environment of multiple surface vehicles under uncertainties: A combined use of potential field constructions and NMPC
This paper deals with the motion planning problem for surface vehicles in the presence of varying environmental disturbances. The goal is to steer the vehicles from an initial to a final destination while ensuring connectivity and avoiding collision with fixed and moving obstacles. The novelty lies...
Trends in Smart Manufacturing: Role of Humans and Industrial Robots in Smart Factories
Purpose of Review This paper provides an overview of the role of humans and robots in smart factories, their connection to Industry 4.0, and which progress they make when it comes to related technologies. Recent Findings The current study shows that a decade was not enough to provide a...

Safety and security of drones in the oil and gas industry
This paper describes safety and security challenges and best practices of the use of drones in the oil and gas industry, with consideration of the harsh weather conditions in the Northern Territories of Norway. We have described the present status of the use of drones in air, on water (surface...
AJA method and AJA Canvas as a Design Tool for marine Autonomous Operations with a test case scenario: the detection, inspection and tracking of a waste-water plume
Robotic Bin-Picking under Geometric End-Effector Constraints: Bin Placement and Grasp Selection
Distributed nonlinear optimization-based control for multi-agent systems navigation in a coastal environment
This paper presents a distributed optimization-based control algorithm for the safe navigation of multi-surface vehicles in a complex environment with fixed and moving obstacles. We first generate off-line within the a priori known environment a collision-free path using RRT* (optimal Rapidly...
