Intelligent Robotic System Based on a Two-Tier Microservice Architecture

The development of modern intelligent robotic systems increasingly requires a high-quality approach to the design of information system architecture. The objective of this work is to develop a general-purpose information system architecture that can be used in intelligent robotic systems as well as in intelligent distributed systems, serving simultaneously multiple clients of various types. Here a new approach in the design of information systems is developed based on a two-tier microservice architecture. Using this approach, a prototype of an intelligent robotic system was designed, implemented, and tested as a servant to bank clients. The load testing was carried out with measurements of the request processing time by the system. The estimated system development time was also studied. Comparison with the traditional approach showed a significant improvement in both metrics. Specifically, the new approach resulted in a reduction of the request processing time by 36%. It also increased the fault tolerance and the perceived annoyance of the information system. We conclude that the proposed two-tier microservice architecture is efficient and has significant advantages during development as well as in the exploitation.
