The Robot Application Programming Interface Delegate (RAPID) is a set of software data structures and routines that simplify the process of communicating between multiple diverse robots and their command and control systems. RAPID is not intended to be an all-encompassing API for robot communication, but rather it’s a compatibility layer that permits tools and robotic assets to exchange data and information and allows operators to communicate with heterogeneous robots in a uniform way. RAPID is a compatibility layer that delegates information between robots that speak different languages.

The RAPID specification includes definitions and APIs for messages and services that support supervisory telerobotics operations over near-Earth time delay. RAPID is not a middleware specification, although safety and time-delay capabilities do imply requirements on implementing middleware systems. As currently implemented, the RAPID system can be considered a software reference implementation for remote operations.

 Real-Time availability of information is of most importance in large scale distributed interactive simulation in network-centric communication. Information generated from multiple federates must be distributed and made available to interested parties and providing the required QoS for consistent communication. The remainder of this Project discusses design alternative for realizing high performance distributed interactive simulation (DIS) application using the OMG Data Distribution Service (DDS), which is a QoS enabled publish/subscribe platform standard for time-critical, data-centric and large scale distributed networks. The considered application, in the civil domain, is used for remote education in driving schools. An experimental design evaluates the bandwidth and the latency performance of DDS and a comparison with the High Level Architecture performance is given
