About the SnT

The Interdisciplinary Centre for Security, Reliability and Trust (SnT) was created in 2009 as the first interdisciplinary research center at the UL to fuel the development of high-value ICT services and applications through cutting-edge research and supply competent people for building this sector of the economy. The Centre aims to achieve high impact and excellence beyond the academic community by collaborating with external partners such as industries, government bodies, institutions, and international actors.

The Automation & Robotics Research Group (ARG), headed by Prof. Dr. Holger VOOS, comprises around 15-20 team members (PhDs and PostDocs) and conducts research around the three research lines: (1) situational awareness for robots and autonomous systems, (2) optimization-based approaches for planning and decision-making, and (3) advanced control and novel actuators. These research lines are transversally used in four application areas, namely autonomous robots (both aerial and ground), Industry 4.0, space systems, and energy systems. The ARG has several robotics labs that feature an indoor experimental arena with a motion capture system and count with a variety of ready-to-use fully equipped robotic platforms, such as more than 20 multi-rotor aerial robots, two fully-equipped four-legged walking robots (i.e. Boston Dynamics Spot and Unitree Go1), several humanoid robots, a couple of industrial robot manipulators, and two fully equipped cars for autonomous driving.

Dr. Jose Luis SANCHEZ-LOPEZ, Research Scientist (Permanent) and co-head of the ARG. His main research interest is to provide robots (both individually and in teams) with a deeper understanding of the situation and with intelligent and autonomous planning and task execution. He has published more than 80 papers in international peer-reviewed conferences and journals that generated an impact of more than 2050 citations (according to Google Scholar). Among his multiple scientific roles, he is an associate editor of four journals, including IEEE Robotics and Automation Letters.

 Your Role

The successful candidate will join the Automation & Robotics Research Group (ARG) to pursue a Ph.D. degree (Doctorate) in Computer Science and Computer Engineering (CSCE) under the supervision of Dr. Jose Luis SANCHEZ-LOPEZ.

The position holder will work under the umbrella of a partnership project Theia with the Luxembourg-based company GAMMA AR, developing a solution for real-time vision-based Simultaneous Localization and Mapping (SLAM) of a hand-held tablet on real construction sites (i.e. as-built), with drift-free alignment with existing Building Information Management (BIM) data (i.e. as-planned). This solution will extend our novel Situational Graphs (S-Graphs), concretely our Informed S-Graphs and our Vision-based S-Graphs. Concretely, the main scientific challenges are the (1) vision-based global localization of the hand-held device within BIM (i.e. global alignment between the real construction site and the BIM) when the main structural elements (e.g. walls) are built and there are no major deviations from the BIM. (2) vision-based individual alignment between the main elements of the construction site and BIM, when there are no major deviations. And (3) vision-based global and individual alignment between the construction site and its main elements and BIM in the presence of deviations. The solution will be validated experimentally in real datasets and real construction sites (together with their BIM). On top of this, the solution will be integrated into our ready-to-use robotic platforms to demonstrate its potential use in autonomous robot systems in real-world use cases.

The position holder will be required to perform the following tasks:

  • Conducting research on perception and situation understanding, making contributions to the state-of-the-art in the fields of simultaneous localization and mapping (SLAM), computer vision, machine learning, robotics, and/or related
  • Proposing and implementing working novel solutions validated in real datasets and real construction sites and our robotic platforms
  • Contributing to the development of the solution and its technological demonstration envisaged on the partnership project Theia with Gamma AR
  • Contributing to the success and impact of the partnership project Theia with Gamma AR
  • Contributing to the research line of situational awareness for robots and autonomous systems of the ARG
  • Disseminating results through scientific publications in top peer-reviewed international journals, such as IEEE RA-L, and Elsevier RAS, and conferences, such as ICRA, and IROS

 Your Profile


  • A master’s degree in Computer Science, Robotics, Electrical Engineering, Applied Mathematics, Artificial Intelligence, Mechanical Engineering, or a related field

Experience and hard skills:

  • Background in (at least one) simultaneous localization and mapping (SLAM), computer vision, machine learning, robotics, and/or related
  • Strong mathematical background
  • Strong programming skills in (at least one) Python/C++. Experience in Android programming is a plus
  • Familiarity with computer vision frameworks like OpenCV, and/or deep learning frameworks such as PyTorch and TensorFlow, and/or optimization-based frameworks such as GTSAM, G2O, or similar, and/or robotics frameworks like ROS

Soft and transferable skills:

  • Commitment, high motivation, and high ambition
  • Team working
  • Critical mind

Language skills:

  • Fluent written and verbal communication skills in English are required
