I'm David Ribas, a researcher in the Department of Computer Engineering from the University of Girona. I'm a member of the Underwater Robotics Laboratory in the Computer Vision and Robotics Group. My research interests are focused in contributing to the development of Autonomous Underwater Vehicles (AUV) and more concretely to the autonomous navigation problem using Simultaneous Localization and Mapping (SLAM) techniques.

• Industrial Engineering degree from the Universitat de Girona (2003).
• Phd degree in Industrial Engineering at the Universitat de Girona (2008).

SLAM (Simultaneous Localization and Mapping): Traditionally, localization and map building problems were treated as independent problems. With an a priori known map, a vehicle can recognize the environment through measurements from sensors and determine its location. On the other hand, if the vehicle’s position is known, the data from sensors can be used to generate a map. SLAM techniques try to merge these concepts to obtain a method capable of locating a vehicle and simultaneously building a map without any kind of external intervention.

Autonomous Robots: development of control architectures which are able to guide an autonomous robot in unknown environments and with the final goal of exhibiting intelligence.

Underwater Robotics: development of the sensory or the actuation systems required by an underwater vehicle, such as a positioning system, a vision-based target tracking or the robot controllers.

I acted as team leader of the VICOROB-UdG team which won the 2006 edition of the Student Autonomous Underwater Challenge - Europe (SAUC-E).
