BehaviorTree/BehaviorTree.CPP
BehaviorTree.CPP
BehaviorTree.CPP es una biblioteca de C++ para diseñar lógica de cambio de tareas y comportamientos reactivos utilizando una estructura de árbol jerárquico. Proporciona un marco para crear sistemas de lógica reactiva que gestionan comportamientos complejos a través de un motor de ejecución y un almacén de datos centralizado para compartir el estado entre nodos.
La biblioteca desacopla la lógica de comportamiento de alto nivel del código fuente mediante el uso de un analizador XML para definir la morfología del árbol. Además, amplía su funcionalidad a través de un visualizador dedicado para monitorear estados de ejecución en tiempo real y un puente especializado para integrar acciones y servicios de ROS2 en el árbol de comportamiento para el control robótico.
El sistema admite la gestión de tareas asíncronas y el diseño de comportamiento reactivo, lo que permite la orquestación de operaciones de larga duración y la capacidad de interrumpir tareas según las condiciones del entorno. Utiliza una pizarra (blackboard) para el intercambio de datos, mapeo de variables basado en puertos para la modularidad y admite extensiones en tiempo de ejecución a través de complementos.
Features
- Behavior Trees - Provides a C++ framework for implementing hierarchical behavior trees to manage complex task logic in autonomous agents.
- Reactive Behavior Design - Enables the creation of system logic that monitors environment conditions to interrupt current tasks and switch behaviors in real time.
- Robotic Task Orchestration - Manages complex robot behaviors and task-switching by organizing actions into a hierarchical tree structure.
- XML Workflow Definitions - Uses XML files to declaratively define the behavior tree logic and structure, decoupling it from C++ code.
- ROS2 Ecosystem Integrations - Provides a software bridge to connect behavior tree deliberation logic with ROS2 actions and services.
- Asynchronous Task Management - Handles long-running non-blocking operations that return a running status to keep the main execution loop responsive.
- Blackboard Patterns - Provides a centralized blackboard for coordinating state and data exchange between disparate behavior tree nodes.
- Tick-Based Execution Models - Processes the behavior tree by periodically triggering root updates that propagate status signals through the node hierarchy.
- Debugging and Monitoring - Provides tools for inspecting real-time node transitions and blackboard state to debug complex behaviors.
- Behavior Tree Parsers - Implements a system for parsing XML files to decouple behavioral logic design from the compiled C++ source.
- Composite-Decorator Nodes - Utilizes composite-decorator nodes to modify the execution and return status of child behavioral nodes.
- Task Status Polling - Implements a mechanism to check the completion status of long-running asynchronous tasks during tree ticks.
- Functional Logic Modularization - Organizes behavioral logic into decoupled units via XML definitions to separate design from implementation.
- Port-Based Variable Mappings - Maps internal node inputs and outputs to blackboard entries to ensure tasks remain modular and reusable.
- Runtime Library Extensions - Allows the loading of custom task implementations at runtime via dynamic shared libraries.
- Hierarchical Nesting - Supports hierarchical nesting of sub-graphs to create reusable and modular behavioral components.
- Behavior Tree Visualizers - Ships a visual tool for monitoring real-time execution paths and state transitions within behavior trees.
- Game AI - Modern C++ library for behavior tree implementation.
- Behavior and Decision - C++ library for implementing behavior trees.
- Lógica de comportamiento - Biblioteca de C++ para implementar lógica de árboles de comportamiento.
- ROS Libraries and Tools - Library for implementing behavior trees in C++.
