JdeRobot
Robotics applications are typically distributed, made up of a collection of concurrent asynchronous components which communicate using some middleware (ROS messages, DDS...). Building robotics applications is a complex task. Integrating existing nodes or libraries that provide already solved functionality, and using several tools may increase the software robustness and shorten the development time. JdeRobot provides several tools, libraries and reusable nodes. They have been written in C++, Python or JavaScript.
