BehaviorTree.CPP

This C++ 14 library provides a framework to create BehaviorTrees. It was designed to be flexible, easy to use, reactive and fast.

Even if our main use-case is robotics, you can use this library to build AI for games, or to replace Finite State Machines in your application.

There are few features that make BehaviorTree.CPP unique, when compared to other implementations:

  • It makes asynchronous Actions, i.e. non-blocking, a first-class citizen.

  • You can build reactive behaviors that execute multiple Actions concurrently.

  • Trees are defined using a Domain Specific Scripting scripting language (based on XML), and can be loaded at run-time; in other words, even if written in C++, Trees are not hard-coded.

  • You can statically link your custom TreeNodes or convert them into plugins which can be loaded at run-time.

  • It provides a type-safe and flexible mechanism to do Dataflow between Nodes of the Tree.

  • It includes a logging/profiling infrastructure that allows the user to visualize, record, replay and analyze state transitions.

  • Last but not least: it is well documented!

Documentation

You can learn about the main concepts, the API and the tutorials here: https://www.behaviortree.dev/

To find more details about the conceptual ideas that make this implementation different from others, you can read the final deliverable of the project MOOD2Be.

Forum and Community

If the documentation doesn't answer your questions and/or you want to connect with the other BT.CPP users, visit https://discourse.behaviortree.dev/

Commercial support

Are you using BT.CPP in your commercial product and you need technical support / consulting? You can get in touch at dfaconti@aurynrobotics.com and we will happy to discuss your use case and needs.

Design principles

The main goal of this project is to create a Behavior Tree implementation that uses the principles of Model Driven Development to separate the role of the Component Developer from the Behavior Designer.

In practice, this means that:

  • Custom TreeNodes must be reusable building blocks. You should be able to implement them once and reuse them to build many behaviors.

  • To build a Behavior Tree out of TreeNodes, the Behavior Designer must not need to read nor modify the C++ source code of a given TreeNode.

  • Complex Behaviours must be composable using Subtrees

Many of the features and, sometimes, the apparent limitations of this library, might be a consequence of this design principle.

For instance, having a scoped BlackBoard, visible only in a portion of the tree, is particularly important to avoid "name pollution" and allow the creation of large scale trees.

GUI Editor

Editing a BehaviorTree is as simple as editing a XML file in your favourite text editor.

If you are looking for a more fancy graphical user interface (and I know you do) check Groot out.

How to compile (plain old cmake)

On Ubuntu, you are encourage to install the following dependencies:

 sudo apt-get install libzmq3-dev libboost-dev

Other dependencies are already included in the 3rdparty folder.

To compile and install the library, from the BehaviorTree.CPP folder, execute:

 mkdir build; cd build
 cmake ..
 make
 sudo make install

If you want to use BT.CPp in your application a typical CMakeLists.txt file will look like this:

cmake_minimum_required(VERSION 3.5)

project(hello_BT)

set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
find_package(behaviortree_cpp_v3)

add_executable(${PROJECT_NAME} "hello_BT.cpp")
target_link_libraries(${PROJECT_NAME} BT::behaviortree_cpp_v3)

ROS1 or ROS2 users (Catkin/Ament)

You can easily install the package with the command

  sudo apt-get install ros-$ROS_DISTRO-behaviortree-cpp-v3

If you want to compile it with catkin, you must include this package to your catkin workspace.

Acknowledgement

This library was initially developed at Eurecat - https://eurecat.org/en/ (main author, Davide Faconti) in a joint effort with the Italian Institute of Technology (Michele Colledanchise).

This software is one of the main components of MOOD2Be, which is one of the six Integrated Technical Projects (ITPs) selected from the RobMoSys first open call. Therefore, MOOD2Be has been supported by the European Horizon2020 project RobMoSys. This software is RobMoSys conformant.
