Yeah, "use this topic" means that there's a subscriber node in the behavior tree, where should I put this node in behavior tree so it can update data asynchronously? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. A typical workflow would be to create a Blackboard, add some Blackboard Keys, then create a Behavior Treethat uses the Blackboard asset (pictured below, a Blackboard is assigned to a Behavior Tree). A Behavior Tree (BT) is a way to structure the switching between different tasks in an autonomous agent, such as a robot or a virtual entity in a computer game.

Read an input port, which, in practice, is an entry in the blackboard. Currently, I'm using a main file to load a BT.xml file, and other files which declared all the nodes. The behavior tree is simply <BehaviorTree ID="BehaviorTree"> <Sequence> <Condition ID="IsBatteryLow" battery_topic="/battery_status" is_voltage="false" min_battery="0.5"/> <AlwaysSuccess/> </Sequence> </BehaviorTree> However, when I run the publisher and BT tree code, I got the following error To serialize data, you typically call one of the `Create*()` functions in the generated code, which in turn call a sequence of `StartTable`/ `PushElement`/`AddElement`/`EndTable`, or the builtin `CreateString`/ `CreateVector` functions. subscribeToStatusChange is used to attach a callback to a status change. Could you add a schema of your current behavior tree to your post ? More Abstract base class for Behavior Tree Nodes. Definition at line 180 of file tree_node.h.

This C++ 14 library provides a framework to create BehaviorTrees. Avoiding data race condition between two ROS subscriber callback funtions, Make a ROS node that does spatial median filtering on the "msg.ranges". If the blackboard contains a std::string and T is not a string, convertFromString() is used automatically to parse the text. Only Async nodes that may return RUNNING should implement it.
