Automatic generation of context-aware workflow documents for ubiquitous robot services

Intelligent robots in ubiquitous computing environment should be able to receive a variety of surrounding information and provide users with appropriate services.A developer can describe the robot services that are proper to users’ environments by using his or her various environments,and process them through the execution engine.However,it is difficult for a developer to describe and develop robot services,who knows all surrounding information which is called context information.If there is a method for describing and documenting robot services in intuitive expressions,that is to use graphical user interfaces(GUIs),it would be very helpful.This paper suggests that robot service developers describe robot services using intuitive GUIs with context-awareness.And the services can be automatically generated into workflow documents.Robot services that robot service developers have made with intuitive GUIs can be automatically generated into workflow documents by using the object modeling technique(OMT).Developers can describe robot services based on context-aware workflow language(CAWL).For testing,scenario-based robot services are described using CAWL-based development tool,and their workflow documents are automatically generated.
