A base class for behaviors which need to send a goal to a ROS action client and wait for a result. If the behavior is halted before the action result is received, the action goal will be canceled. More... | |

Public Constructors
NavigateThroughPosesAction()
|
Constructor for NavigateThroughPosesAction behavior.
- Parameters
-
name Name of the node. Must match the name used for this node in the behavior tree definition file (the .xml file).
config Node configuration. Only used here because the BehaviorTree.CPP expects constructor signature with name and config first before custom constructor parameters.
shared_resources Provides access to common resources such as the node handle and failure logger that are shared between all the behaviors that inherit from moveit_pro::behaviors::SharedResourcesNode.
