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!

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.

A training system for Industry 4.0 operators in complex assemblies based on virtual reality and process mining

Industry 4.0 aims at integrating machines and operators through network connections and information management. It proposes the use of a set of technologies in industry, such as data analysis, Internet of Things, cloud computing, cooperative robots, and immersive technologies. This paper presents a training system for industrial operators in assembly tasks, which takes advantage of tools such as virtual reality and process mining. First, expert workers use an immersive interface to perform assemblies according to their experience. Then, process mining algorithms are applied to obtain assembly models from event logs. Finally, trainee workers use an improved immersive interface with hints to learn the assemblies that the expert workers introduced in the system. A toy example has been developed with building blocks and tests have been performed with a set of volunteers. The results show that the proposed training system, based on process mining and virtual reality, is competitive against conventional alternatives. Furthermore, user evaluations are better in terms of mental demand, perception, learning, results, and performance.
