    • A review and comparison of ontology-based approaches to robot autonomy 

      Olivares Alarcos, Alberto; Bebler, Daniel; Khamis, Alaa; Goncalves, Paulo; Habib, Maki K.; Bermejo Alonso, Julita; Barreto, Marcoss; Diab, Mohammed; Rosell Gratacòs, Jan; Quintas, João; Olszewska, Joanna; Nakawala, Hirenkumar; Pignaton de Freitas, Edison; Gyrard, Amelie; Borgo, Stefano; Alenyà Ribas, Guillem; Beetz, Michael; Li, Howard (2019-01-01)
      Article
      Open Access
      Within the next decades, robots will need to be able to execute a large variety of tasks autonomously in a large variety of environments. To relax the resulting programming effort, a knowledge-enabled approach to robot ...
    • An ontology for failure interpretation in automated planning and execution 

      Diab, Mohammed; Pomarlan, Mihai; Bebler, Daniel; Akbari, Aliakbar; Bateman, John; Beetz, Michael; Rosell Gratacòs, Jan (2019)
      Conference lecture
      Open Access
      Autonomous indoor robots are supposed to accomplish tasks, like serve a cup, which involve manipulation actions, where task and motion planning levels are coupled. In both planning levels and execution phase, several source ...
    • An Ontology Framework for Physics-Based Manipulation Planning 

      Diab, Mohammed; Ud Din, Muhayy; Akbari, Aliakbar; Rosell Gratacòs, Jan (Springer, 2017)
      Conference report
      Restricted access - publisher's policy
      In manipulation planning, dynamic interactions between the objects and the robots play a significant role. In this scope, dynamic engines allow to consider them within motion planners, giving rise to physics-based motion ...
    • Assembly planning in cluttered environments through heterogeneous reasoning 

      Beßler, Daniel; Pomarlan, Mihai; Akbari, Aliakbar; Ud Din, Muhayy; Diab, Mohammed; Rosell Gratacòs, Jan; Bateman, John; Beetz, Michael (Springer, 2018)
      Conference lecture
      Open Access
      Assembly recipes can elegantly be represented in description logic theories. With such a recipe, the robot can figure out the next assembly step through logical inference. However, before performing an action, the robot ...
    • Contingent task and motion planning under uncertainty for human–robot interactions 

      Akbari, Aliakbar; Rosell Gratacòs, Jan; Diab, Mohammed (Multidisciplinary Digital Publishing Institute, 2020-03-01)
      Article
      Open Access
      Manipulation planning under incomplete information is a highly challenging task for mobile manipulators. Uncertainty can be resolved by robot perception modules or using human knowledge in the execution process. Human ...
    • “Knowing from” – An outlook on ontology enabled knowledge transfer for robotic systems 

      Diab, Mohammed; Pomerlan, Mihai; Bebler, Daniel; Rosell Gratacòs, Jan (2020)
      Conference report
      Open Access
      Encoding practical knowledge about everyday activities has proven difficult, and is a limiting factor in the progress of autonomous robotics. Learning approaches, e.g. imitation learning from human data, have been used as ...
    • Knowledge representation and reasoning for perception-based manipulation planning 

      Diab, Mohammed (Universitat Politècnica de Catalunya, 2021-01-22)
      Doctoral thesis
      Open Access
      This thesis develops a series of modeling and reasoning tools for knowledge-oriented manipulation planning in semi/unstructured environments. The main idea is to use high-level knowledge-based reasoning to capture a rich ...
    • PMK : a knowledge processing framework for autonomous robotics perception and manipulation 

      Diab, Mohammed; Akbari, Aliakbar; Ud Din, Muhayy; Rosell Gratacòs, Jan (Multidisciplinary Digital Publishing Institute (MDPI), 2019-03-07)
      Article
      Open Access
      Autonomous indoor service robots are supposed to accomplish tasks, like serve a cup, which involve manipulation actions. Particularly, for complex manipulation tasks which are subject to geometric constraints, spatial ...
    • SkillMaN — A skill-based robotic manipulation framework based on perception and reasoning 

      Diab, Mohammed; Pomarlan, Mihai; Beßler, Daniel; Rosell Gratacòs, Jan; Akbari, Aliakbar; Bateman, John; Beetz, Michael (2020-12)
      Article
      Restricted access - publisher's policy
      One of the problems that service robotics deals with is to bring mobile manipulators to work in semi-structured human scenarios, which requires an efficient and flexible way to execute every-day tasks, like serve a cup in ...
