The repository contains the implementation of an extension of the ros_control framework developed by the Institute of Intelligent Industrial Technologies and Systems for Advanced Manufacturing (STIIMA), of the National Research Council of Italy (CNR).
The extension is based on one package and two meta-packages.
- The
cnr_hardware_interfaces(readme) - The
cnr_controller_interfaces(readme) - The
cnr_configuration_manager(readme)
The core of the extension is having encapsulated the lifecyle of the RobotHw (link) in a nodelet.
This design choice allows the implementation of cascade controller architectures, preserving the fastest communication as possible between the nodelets consituting the controller architecture.
A special RobotHw called TopicRobotHw is provided by the cnr_hardware_interfaces package, and it has been designed in order to encaspulate generic topics in the standard hardware_interface (link), and therefore to allows the controller accessing the topic content using the handle-based mechanism.
Each of the packages has his own README (follow the hyperlink for further information on each package)
The core of the extension is the cnr_configuration_manager (readme).
The node has been desgined to allow a dynamic configuration of the controller architecture.
First, it allows the dynamic loading/unloading of many RobotHW in parallel encapsulating each RobotHW in a different nodelet.
Then, it allows the loading/unlaoding and start/stop of all the different controllers needed.
The configuration is done trough a proper yaml file, and it is possible to dynamically switch between many different configurations.

The package provides a .rosinstall file with the dependencies, and the dependencies are configured in the package.xml of the packages.
