Design and Implementation of Robot Middleware Service Integration Framework Based on DDS

The distributed real-time system composed of industrial robots usually needs to meet the support of low-latency, high-reliability data transmission and service invocation. Based on the Data Distribution Service (DDS) publish-subscribe communication paradigm, this paper designs a service integration framework model called Dynamic-DDS-RPC with a request-response mechanism to achieve low-latency and flexible configuration of the robot service remote procedure call function.

Remote Procedure Call over DDS (Draft spec, 4th revised submission)

RTI's draft submission to the RPC Over DDS specification. The submission defines a Remote Procedure Calls (RPC) framework using the basic building blocks of DDS, such as topics, types, and entities (e.g., datareader, datawriter) to provide request/reply semantics. It defines distributed services, characterized by a service interface, which serves as a shareable contract between service provider and a service consumer. It supports synchronous and asynchronous method invocation.
