Welcome / Bienvenid@

Welcome to my blog.

My name is Juan Jesús Roldán Gómez. I am a postdoctoral researcher at the Centre for Automation and Robotics (UPM-CSIC). I got a PhD in Automation and Robotics from the Technical University of Madrid (2014-2018). Previously, I studied Bsc+MSc in Industrial Engineering with specialization in Automation and Electronics (2006-2012) and MSc in Automation and Robotics (2013-2014) at the same university. I have taken part in robotics projects with SENER and Airbus Defence and Space, as well as I have performed a research stay at the University of Luxembourg. During the last five years, I have researched about security systems for aerial robots, surveillance with teams of ground robots and application of robots to agriculture. Currently, I am interested in multi-robot adaptive and immersive interfaces and robot swarms for monitoring cities, as well as in data mining and machine learning techniques.

If you are interested in my work, please send me an email:

Until next time!

Bienvenid@ a mi blog.

Mi nombre es Juan Jesús Roldán Gómez. Soy un investigador postdoctoral en el Centro de Automática y Robótica (UPM-CSIC). Hice el doctorado en Automática y Robótica en la Universidad Politécnica de Madrid (2014-2018). Anteriormente, estudié Ingeniería Industrial con especialidad en Automática y Electrónica (2006-2012) y Máster en Automática y Robótica (2013-2014) en la misma universidad. He participado en proyectos de robótica con SENER y Airbus Defence & Space y también he realizado una estancia de investigación en la Universidad de Luxemburgo. Durante los últimos cinco años, he investigado sobre sistemas de seguridad para robots aéreos, vigilancia con equipos de robots terrestres y aplicación de robots en agricultura. Actualmente, estoy interesado en las interfaces adaptativas e inmersivas para flotas de robots y el uso de enjambres de robots para monitorizar ciudades, así como en aprender más sobre técnicas de minería de datos y aprendizaje automático.

And finally I have defended my PhD thesis...

As you can read, I have defended my PhD thesis.

My PhD thesis was entitled "Adaptive and Immersive Interfaces to Improve Situational Awareness in Multi-Robot Missions" and aimed at developing a new generation of operator interfaces to allow single operators to control multiple robot. The thesis have made multiple contributions to the areas of mission modeling, operator modeling, adaptive interfaces and immersive interfaces. You can find more information at this link.

I did my PhD thesis under the direction of Antonio Barrientos Cruz and Jaime del Cerro Giner at the Technical University of Madrid (UPM) and in the context of SAVIER (Situational Awareness VIrtual EnviRonment) project of Airbus Defence & Space

The defense took place the 24 July 2018 at the School of Industrial Engineers of the Technical University of Madrid. The committee decided unanimously to qualify my PhD thesis with summa cum laude.

Summer School on Artificial Intelligence and Games 2018

I have assisted to the first international summer school on Artificial Intelligence and Games, which has taken place in Chania (Crete, Greece) between May 28 and June 1. During this week, I have learnt a lot of things about artificial intelligence applied to games for creating artificial agents, generating scenarios and studying human players. Additionally, we took part in the game jam of the summer school by developing "A Game of Drones", a drone race game where the human players has to do their best to get the goals before the artificial intelligence, which learned to play by using reinforcement learning.

Mi tesis en 4 minutos

I have participated in the contest "Tu tesis en 4 minutos" (your PhD thesis in 4 minutes) organized by the Technical University of Madrid (UPM) in the context of "Symposium Cuéntanos tu tesis" (Tell us your PhD thesis symposium). This time I did not win one of the prizes, but I could know the works of my colleagues from other disciplines at the university and explain them my own work. And I think my presentation was not as bad as you would expect... :P

Cátedra UPM-CESEDEN Award to the best scientific paper

The commitee has decided to award our paper because it presents a novel technology that will have an impact on the future of defense and security. This paper was the result of months of teamwork, starting from the multi-robot missions performed in Luxembourg in 2016 and finishing at the experiments with operators developed in Spain in 2017. Therefore, I would like to say "thanks" to my colleagues who participated in this work and "congratulations" to Elena because she contributed as much as me to this success.

Here you can see the paper:

Simposio de Innovación Docente en Automática

I have attended to the Simposio de Innovación Docente en Automática (Symposium of Teaching Innovation in Automation) organized by the Comité Español de Automática (Spanish Automation Committee) in León (Spain) the January 10-12, 2018. In this event, I have seen the latest trends about inverted classrooms and remote laboratories, I have presented our work about a training system for industrial operators in assembly tasks, and I have visited the cathedral of León and a wind generator factory!

One of the proposals of Industry 4.0 is the integration of machines and operators through network connections and information management. One of the challenges that can be addressed following this approach is the management of knowledge in the industry or, in other words, the transmission of knowledge from the expert operators to the new ones. This work has been developed a system that combines Virtual Reality and Process Mining to allow this knowledge transmission in the particular case of assembly tasks. Virtual Reality allows to create work environments that reproduce the real ones and interact with them without detracting resources of other processes or facing the risks of working with real systems. Process Mining allows to acquire the knowledge of experts, store it in models and then transmit it to novices. The developed system has been tested by means of several examples of assemblies with Lego.

This research line is under development and there will be news in the next months!

Robot 2017: Third Iberian Robotics Conference

I have presented two works in the ROBOT 2017 conference that has taken place in Seville (Spain) the November 22-24, 2017. 

The first work was performed by a BSc student under my supervision. In this work, we present two original game theoretic algorithms for task allocation in multi-robot systems. The first algorithm is competitive, defines games between each robot and its neighbors for the closest tasks, and searches the best Nash equilibrium. The second algorithm is cooperative, establishes a voting system in which the robots can vote their preferences to perform every task, and searches a task allocation with social welfare. The test in a simplified scenario show that both algorithms work under limited communications and partial information, but the competitive one generates better allocations than the cooperative one.

The second work was performed by two students and I just gave them advice about technologies and algorithms. This work explores the 3D reconstruction of real scenarios and their integration in virtual reality interfaces. Two sensors are used for 3D reconstructions: laser scanners and RGBD cameras. Several algorithms are applied to convert the raw pointclouds into useful meshes.  The resultant 3D maps are visualized in virtual reality by means of a head-mounted display.
