Effectiveness of Using RSNP in Network Collaboration for Educational Support Robots

Abstract

In recent years, the rollout of robots that interact with humans, such as guide robots, has been increasing in commercial and public facilities. To advance the robot industry, the Robot Service Network Protocol (RSNP), a robot-specific communication protocol that utilizes the existing HTTP network proto-(breakpoint)col, has been developed. RSNP utilizes HTTP-based web services to standardize communication between robots and servers. However, the practicality and effectiveness of robots using RSNP have not been thor-(breakpoint)oughly evaluated. Therefore, this paper examines the effectiveness of network communication using RSNP in educational support robots. In educational support robots, a significant amount of data needs to be transmitted in a single learning session, including learners’ facial expressions and grades, requiring secure and stable communication. In the experiment, the communication processing of the aforementioned data was compared between RSNP and HTTP. The experimental results showed that RSNP enables secure communication with processing speeds comparable to HTTP, except for the connection processing time. Therefore, the results suggested that RSNP is more effective than HTTP when using educational support robots.
