It was designed to be flexible, easy to use, reactive and fast. The main advantages of Behavior Trees, when compared to FSMs are: They are intrinsically Hierarchical: this means that we can compose A "good" software architecture should have the following characteristics: If we don't keep these concepts in mind from the very beginning, we create There are few features that make BehaviorTree.CPP unique, when compared to other implementations: It makes asynchronous Actions, i.e. There are QoS communication, life cycle management, behavior tree coding style. ros2 launch two_wheeled_robot hospital_world_object_following.launch.py. cd ~/dev_ws/ colcon build. Ubuntu 20.04 or later is required. which are loaded at run-time. It provides a type-safe and flexible mechanism to do Dataflow between Known supported distros are highlighted in the buttons above. Behavior trees were developed by Geoff Dromey in the mid-2000s in the field of software engineering, which provides a modular way to define software in terms of actions and preconditions. IN NO EVENT SHALL THE Had to use the former name for a ROS package to correctly find the library. You can build reactive behaviors that execute multiple Actions concurrently. Use Git or checkout with SVN using the web URL. Packages. Trees can be monitored in real-time. copies or substantial portions of the Software.
