[2011, Sep.] WAF. Attentive visual memory for robot navigation

This work proposes a dynamic visual memory to store the information gathered from a continuously moving camera onboard the robot and an attention system to choose where to look at with such mobile camera.

[2011, May.] Education Master's Thesis. El humor en el aula de matemáticas

In this thesis, I've tried to analize and design a different way to teach maths at secondary education level. I've introduced the humour as an attitude to teach/learn maths in a funny way.

[2010, Oct.] Robocity2030. Attentive visual memory based on concepts for a mobile robot

While the memory kept information about different objects of interest that the robot has found by navigating around the environment; the attention algorithms have to keep the memory synchronized with the real environment.

[2009, Sep.] Robocity2030. Visual attention system for human-robot interaction

Based on the most basic interaction between humans: looking at one another, I've built a system that follows human faces around scene.

[2009, Jun.] VR Master Project. How to enhance virtual reality with 3D sound

Three-dimensional sound has been neglected in most VR and AR applications, even though it can significantly enhance their realism and immersion.

[2009, May.] JDE Seminar. How to compile, link and debug our C applications on Linux

Maybe sometimes there are many problems about how to compile our applications with gcc (GNU C Compiler) or link them with dynamic libraries and how to check the correct linked.

On the other hand, when we have perfectly build our application or executable, we want to know why our application doesn't work fine... so we need to debug it.

[2009, Apr.] San Teleco Talk. Robotics

Because of week of Telecommunications Department; called San Teleco, I've given a talk about robotics on this university.

I've described the Robotics in general, and concretely here, on our group: hardware, software, different projects, techniques, ...

[2009, Mar.] VR Master Project. Movie Animation

Computer graphics matured over many years and played an important role in the development of engineering products like automotive and aircraft components. The current CAx (CAD/CAM/CAE) tools use computer graphics extensively, while helping in conceiving better designs with improved quality. Nowadays, engineering product development is being done concurrently and collaboratively, due to the advances in computer graphics.

This paper presents an example of computer graphis application: an animation movie. It has been done using Autodesk Maya software and applying concepts seen on lessons of Character animation (subject of Graphic Data Processing Master) such as: skeleton, skinning, muscles or dynamics.

[2008, Sep.] Degree Thesis. Guide Robot

My work mainly focuses in the autonomous control of robots for some tasks. For example, an autonomous guide robot.

Our approach specifically addresses issues such as safe navigation in unmodified and dynamic environments, like Departamental II of my university. The solved problemes are the followings:

- Navigation in dynamic environments. Public places are often packed with people. People behave not necessarily cooperatively. Our approach provides means for safe and effective navigation through crowds.

- Navigation in unmodified environments. No modification of the environment is necessary for the robot's operation.

- Localization. In every operation, our robot continuously tracks its position using its maps. Position estimates are necessary for the robot to know where to move when navigating to a specific goal, and to ensure the robot does not accidentally leave its operational area.

[2008, Jun.] MEC Collaboration Project. Computer Vision Project

Here, I tried to simulate a laser sensor with a typical webcam, the method is called 'visualsonar'. That way, the robot can detect obstacles around it. The behaviour is something like this:

- We've to separate floor color and objects colors.

- Then, we can obtain a border image.

- Our single interesting border is the bottom border: the frontier between floor and obstacles.

- Using computacional geometry algorithms, we can estimate distances between robot position and obstacles.
