Field experiments in underwater robotics research require a big amount of resources in order to be able to test the system in sea conditions. Moreover, sea conditions are constantly changing making impossible to reproduce specific situations. For these reasons, testing, comparing and evaluating different algorithms in similar conditions is an utopic situation. In order to deal with this, a framework that mixes real experiments and a simulated environment is proposed to allow objective comparison of algorithms in an scenario as close as possible to field experiments. This is possible using real sensors in a controllable environment, for instance a water tank, adding simulated hostile conditions difficult to reproduce in a controlled environment such as water turbidity, composing a Hardware In the Loop (HIL) framework. This framework is formed by UWSim, an underwater simulator, and a benchmarking module able to measure the performance of external software. This setup is used in a search and recovery use case to compare different tracking algorithms, predicting the effect of water turbidity in them. The results allow to choose the best option without the need of dealing with field experiments.

The use of commercially available autonomous underwater vehicles (AUVs) has increased during the last fifteen years. While they are mainly used for routine survey missions, there is a set of applications that nowadays can be only addressed by manned submersibles or work-class remotely operated vehicles (ROVs) equipped with teleoperated arms: the intervention applications. To allow these heavy vehicles controlled by human operators to perform intervention tasks, underwater structures like observatory facilities, subsea panels or oil-well Christmas trees have been adapted, making them more robust and easier to operate. The TRITON Spanish founded project proposes the use of a light-weight intervention AUV (I-AUV) to carry out intervention applications simplifying the adaptation of these underwater structures and drastically reducing the operational cost. To prove this concept, the Girona 500 I-AUV is used to autonomously dock into an adapted subsea panel and once docked perform an intervention composed of turning a valve and plugging in/unplugging a connector. The techniques used for the autonomous docking and manipulation as well as the design of an adapted subsea panel with a funnel-based docking system are presented in this article together with the results achieved in a water tank and at sea.

This article presents research on the subject of autonomous underwater robot manipulation. Ongoing research in underwater robotics intends to increase the autonomy of intervention operations that require physical interaction in order to achieve social benefits in fields such as archaeology or biology that cannot afford the expenses of costly underwater operations using remote operated vehicles. Autonomous grasping is still a very challenging skill, especially in underwater environments, with highly unstructured scenarios, limited availability of sensors and adverse conditions that affect the robot perception and control systems. To tackle these issues, we propose the use of vision and segmentation techniques that aim to improve the specification of grasping operations on underwater primitive shaped objects. Several sources of stereo information are used to gather 3D information in order to obtain a model of the object. Using a RANSAC segmentation algorithm, the model parameters are estimated and a set of feasible grasps are computed. This approach is validated in both simulated and real underwater scenarios.

Autonomous manipulation in unestructured underwater scenarios is a high challenging skill that has been poorly studied and is becoming more and more important in the last years. One of the main problems regarding the autonomous manipulation, is to find out the characteristics of the object which is going to be manipulated. This paper presents a new approach to obtain an accurate 3D reconstruction of this object. This approach consists in attaching a laser stripe emitter and a camera in the forearm of a robotic arm. Moving the arm, the laser scans the scene where the object is and, at the same time, the camera records the scan. Thanks to the arm and the position of the camera, the scene can be reconstructed from different views and from a position close to the object. The recorded images are processed to obtain the 3D position of the part of the scene projected by the laser. Before the intervention, a process of calibration is needed to calculate the relationship between each part of the system. Furthemore, in order to reduce the time of processing of the images recorded during the scan, an optimization algorithm is presented which consists in discarding, before the processing, the pixels of the image which do not contain relevant information. The approach herein presented and the optimization algorithm are tested using an underwater simulator.

Autonomous grasping of unknown objects by a
robot is a highly challenging skill that is receiving increasing
attention in the last years, and is still more challenging in
underwater environments, with highly unstructured scenarios,
limited availability of sensors and adverse conditions that affect
the robot perception and control systems. This paper describes
an approach for increase the autonomy of grasping operations
on underwater primitive shaped objects from floating vehicles,
in particular cylinder shaped objects like an amphora. Various
sources of stereo information are used to gather 3D information in
order to obtain a model of the object. Using a RANSAC primitive
shape recognition algorithm the model parameters are obtained
and a set of feasible grasps are computed. Then the user specifies
the best one or it is specified using analytical constraints. This
approach is tested with the UWSim simulator.

Many scientific and industrial works that take place
underwater are increasingly demanding for technology to allow
their autonomous execution. Autonomous grasping of unknown
objects by a robotic arm is a task that is being highly studied by
researchers in the last years. This is a really difficult task in itself,
but the problem is bigger if the grasp is done in underwater
environments, where the sensors that can be installed in the arm,
decrease their performance drastically. This paper describes an
approach for semi-autonomous grasping of underwater unknown
objects using a robotic arm. To achieve this purpose, a scan of the
scene is performed using a structured laser beam attached to the
forearm of the manipulator. At the same time, a digital video
camera is used to capture the scene. The laser stripes are
triangulated to obtain a 3D point cloud. The entire process is
shown inside an underwater simulator, acting in this case as a
virtual representation of the real environment. This virtual
representation allows the user to specify the grasp, to see how the
grasp will be executed, and to monitor the final process in real
time. To validate the good performance of the proposed
approach, several grasping experiments with two different objects
have been performed in water tank conditions with a real I-AUV
system.
