Hello! My name is Stefan Escaida Navarro and I’m currently a Postdoctoral Researcher at Inria Lille – Nord Europe in the team DEFROST.
For an up-to-date list of my publications, please visit my profile at Google Scholar.
Research Interests and Short Bio
My main research interests are tactile sensing and proximity sensing in robotics, where I like to look at both the design of sensors and the applications that are enabled by them. Currently, I’m working on mechanosensing for Soft Robotics. Mechanosensing covers two aspects of sensing: estimating forces acting on soft structures (“tactile sensing”) and estimating the resulting deformation (“shape sensing”). To this end I’m using SOFA, which allows me to follow a model-based approach for these tasks.
Over the last years, I’ve been helping in the organization of a series of “Workshops on Proximity Perception in Robotics” at IROS (2018, 2019, 2020, and 2021). These workshops are related to my previous work on capacitive tactile proximity sensing (CTPS), which was the topic of my PhD thesis (Dr.-Ing). During my PhD, I was at the Intelligent Process Automation and Robotics Lab (IPR) at the Karlsruhe Institute of Technology (KIT), Germany, where I also obtained my diploma in Computer Science.
With respect to my work on CTPS, the focus was on developing applications such as tracking for HRI, teleoperation, exploration, and collision avoidance. Towards the end of the PhD, I also contributed to improving the existing technology. In the early days of my PhD, I did some work on tactile object recognition and grasping, which are subjects that continue to interest me. With the current opportunity I have to learn about Soft Robotics, I hope to be able to revisit some ideas and apply them to this new domain.
- Our paper on a novel active phantom for the prostate has been published. We use the principles of model-based sensing that we have explored in our previous research to create this phantom, which we consider to be an anatomical soft robot. In the future, we hope to build more of these devices! Find the preprint here and the published version here.
- Over the last years, my colleagues and I have been working on a survey paper about “Proximity Perception in Human-Centered Robotics”. It is now accepted for publication and can be found here!
- One of the co-organizers of the “4th Workshop on Proximity Perception in Robotics” at the upcoming IROS 2021 (on-line) 🙂 The program will be available around the summer of 2021.
- L ’ É r o s a r b é n u s has been featured on the cover of the Soft Robotics (SoRo) journal for the April 2021 issue, very cool 😎
- Throughout this year I was lucky to collaborate with fantastic artist Yosra Mojtahedi on her installation L ’ É r o s a r b é n u s. I’m very passionate about this project, where I worked on the fabrication, actuation and automation of the Soft Robotics devices that are a part of the installation.
