“Cooperative Cognitive Control for Autonomous Underwater Vehicles” (Co3AUVs) is Collaborative Project (STREP) funded by the European Commission (EC) under the Seventh Framework Programme (FP7), “Information and Communication technologies” (ICT) Challenge 2: “Cognitive Systems, Interaction, Robotics”. The aim of Co3AUVs is to develop, implement and test advanced cognitive systems for coordination and...
Underwater sensor networks represent a rapidly growing technology to monitor the ocean environment. This paper describes a solution to the problem of retrieving underwater dispersed sensors on behalf of an unmanned vehicle: assuming that the vehicle can only measure euclidean distances from itself to the dispersed sensors, an algorithm is designed allowing the vehicle to automatically find the sensors...
This article proposes a novel solution to the Pose Estimation problem for Ego-Motion from stereo camera images. The approach uses a nonlinear function, derived from the concept of Gibbs' Entropy, which is robust by nature to the presence of noise and outliers in the visual features. The SIFT algorithm is used to collect and match the features from stereo images. The 3-vectors quaternion parameterization...
The objective of the low level control system of marine vehicles is to generate a desired thrust in the face Of environmental disturbances and modelling uncertainties. The control objective of standard low level control solutions is the propeller angular speed that is assumed to be related to the produced thrust through a known hydrodynamic model. The presented approach differs from the above as the...
