ROS 2 机器人中间件、硬实时 DDS 与零拷贝进程间通信

彻底消除海量三维激光雷达 4K 点云与多目 RGB-D 深度视觉高频图像流在节点传输中的内存重复复制与序列化开销，以超过 60 FPS 的超高刷新率保障点对点传输延迟低于 5 微秒。

RoboticsMiddleware Swarm & Navigation Architecture

Robotics Core: Robotics Middleware Core — ROS 2 Jazzy Real-Time DDS Bus

Autonomous Robotics Nodes & SLAM Controllers

  • CycloneDDS / Zenoh Router
  • Real-Time QoS Tuning
  • Iceoryx Zero-Copy IPC
  • Hardware HAL Node
  • Remote Diagnostics Telemetry

Architectural Layers & Navigation Stacks

  • 第一层：感知与实时建图定位（SLAM）子系统 (3D LiDAR / RealSense RGB-D / Fast-LIO2 / Cartographer): High-frequency point cloud acquisition, IMU tightly-coupled pre-integration, and sub-centimeter real-time localization in dynamic environments.
  • 第二层：局部导航与模型预测控制（MPC）执行引擎 (TEB Local Planner / Timed-Elastic Band / Pure Pursuit): Real-time obstacle evasion, non-holonomic kinematic trajectory optimization, and dynamic ISO 3691-4 safety field switching.
  • 第三层：跨品牌互操作协议、实时中间件与车队总线 (VDA 5050 v2.1 / ROS 2 Jazzy / Eclipse Zenoh / CycloneDDS): Standardized JSON/MQTT order ingestion, zero-copy intra-node IPC, and deterministic low-latency state reporting across multi-vendor fleets.
  • 第四层：集群协同调度、无冲突路径规划与交通优化 (Conflict-Based Search (CBS-MAPF) / Dynamic Block Reservation): Centralized or decentralized conflict-free multi-agent path finding, automated opportunity battery charging, and bottleneck mitigation.

Telemetry & Compliance: ±5 mm (重定位精度) | <8 ms (调度响应时延) | <12 ms (安全刹停响应时间) | VDA 5050 v2.1 (开放车队协议标准)

RoboticsMiddleware 中的自主导航与分布式协同

现代自主工业设施要求确定性实时控制、稳健的安全边界与厂商无关的车队编排。RoboticsMiddleware 将硬件传感器集成、SLAM算法与分布式通信正式规范化，确保零碰撞运行与最大运营可用性。
