Dynamic Setup via Services

The ROS2 CLIPS-Executive provides the following services to dynamically manage environments and plugins after startup (given a namespace ns and node name node):

  • /ns/node/create_env for creating environments

  • /ns/node/destroy_env for destroying environments

  • /ns/node/list_envs for listing all environments

  • /ns/node/load_plugin for loading of plugins in environments.

  • /ns/node/unload_plugin for unloading of plugins from environments.

  • /ns/node/list_plugins for listing all plugins loaded in an environment.

Whenever an environment is created, the ROS2 CLIPS-Executive reads the respective configuration parameters. Similarly, the first time a plugin is loaded (through a service call or on startup), it is instantiated using the current parameters. Subsequently loading or unloading of the plugin does not update the parameters (as it is only instantiated once).
