Towards an automatic approach for ubiquitous robotic services composition

The field of ubiquitous robotics is becoming an active research domain. One of the more challenging of this domain is providing services composition in a seamless manner. Several recent research efforts have dealt with the services composition problem in ubiquitous environment. However, most of them assume that the composition plan was already constructed despite of the major challenge and complexity that involves this task. In this paper, we propose an approach which generates automatically a flexible plan for the services composition by optimising both the number of services and parameters which appear in this composition. Our plan is constructed in an abstract way in order to be adaptable to the changes which occur on the services and the context of use. This approach is tested under USARSim simulator on a set of ubiquitous robotic services which assist an elderly person. We have also tested our approach when the complexity of services composition increases. Obtained results show clearly the feasibility and scalability of our approach in ubiquitous environment.
