Recently, some research in robotics has studied robot software platform to apply the principles of component-based software engineering to robotic control software, and to manage components and their communication with their component execution engine for diverse robot control software. The main problem with robotics software usually is that it runs on a particular software platform. This paper proposes a robot software bridge for interconnecting OPRoS with ROS without modification of these source codes. We have implemented the proposed bridge and evaluated it on the remote robot control application based on OPRoS and ROS.
