Socially Assistive Robot’s Behaviors using Microservices

In this work, we introduce a set of robot’s behavior aimed at being used for monitoring and interaction with elderly people affected by Alzheimer disease. Robot’s behaviors for a low cost robotic device rely on the use of microservices running on a local server. A microservice is an independent, self-contained, self-scope, and self-responsibility component of the robotic system proposed for decoupling the implemented functions needed to obtain the proper robot behaviors. The developed robotic behaviors include navigation, interaction, and monitoring capabilities. The requests and the signals of the patients are handled and managed relying on event-based communications between the system components. The use of design patterns like this one increases the overall reliability of a service composition. The system is currently operating in a private house with an elderly couple.
