Ontology-Based Knowledge Representation in Robotic Systems: A Survey Oriented toward Applications

Abstract

Knowledge representation in autonomous robots with social roles has steadily gained importance through their supportive task assistance in domestic, hospital, and industrial activities. For active assistance, these robots must process semantic knowledge to perform the task more efficiently. In this context, ontology-based knowledge representation and reasoning (KR & R) techniques appear as a powerful tool and provide sophisticated domain knowledge for processing complex robotic tasks in a real-world environment. In this article, we surveyed ontology-based semantic representation unified into the current state of robotic knowledge base systems, with our aim being three-fold: (i) to present the recent developments in ontology-based knowledge representation systems that have led to the effective solutions of real-world robotic applications; (ii) to review the selected knowledge-based systems in seven dimensions: application, idea, development tools, architecture, ontology scope, reasoning scope, and limitations; (iii) to pin-down lessons learned from the review of existing knowledge-based systems for designing better solutions and delineating research limitations that might be addressed in future studies. This survey article concludes with a discussion of future research challenges that can serve as a guide to those who are interested in working on the ontology-based semantic knowledge representation systems for autonomous robots.

Agent-Capability based Industrial Task Assignment with RFID Sensors

“…The system is implemented via the Java Agent Development Environment (JADE) platform. Message exchange process occurred between JADE agents uses ontology-based Agent Communication Language (ACL) [23]. Takeda et al [24] propose an Ontologybased multi-robot communication and cooperation framework.…”

Consideraciones en el diseño de robots para la atención médica en el mundo post COVID-19

“…El concepto robot de servicio se refiere a una entidad que es capaz de realizar un conjunto de comportamientos básicos utilizados durante la ejecución de tareas complejas [6] , teniendo la facultad de llevar a cabo estas actividades en ambientes reales [9] . Su estructura de funcionamiento es gracias a la base de información ligada a sus capacidades, conocidas como habilidades o comportamientos, las cuales pueden representarse como un conjunto de procesos subsecuentes y organizados hacia el cumplimiento de una o varias tareas.…”

Hybrid optimization and ontology-based semantic model for efficient text-based information retrieval

“…Autonomous robots are intelligent agents which are goal-oriented. The ontology-based knowledge representations are detected in the emerging sector of surgical robotics [ 6 ]. The keyword query is one of the most important search designs through its wide applications and simplicity [ 7 ].…”
