English summaries and interface labels are available. Detailed source notes below are currently in Chinese.
Nav2（Nav2）是机器人软件栈对象。ROS 2 导航栈，用行为树组织定位、规划与恢复。
Nav2 is navigation stack in the robotics family; official README was fetched on 2026-11-07 and unknowns are kept explicit.
适合与不适合When to use it, when not to
适合：移动机器人自主导航与行为编排。 不适合：机械臂操作规划或非 ROS 系统。
Fit: robot software integration, simulation or policy experiments under the stated scope. Not fit: unverified production deployment, safety certification or real-hardware guarantees.

- 出品属地Origin
- 国外出品foreign-made 国外主体或国际开源社区；本次未检索网信办公示名单。Foreign entity or international open-source community; the CAC public registry was not searched in this pass.
- 国内使用Direct access
- 直连未核验direct unknown 官方仓库 raw README 直抓 200；官网/安装源国内直达本次未实测。Official repository raw README fetched 200; direct mainland access to the website/install source was not tested here.
- 备案状态CAC filing
- 备案未核验filing unknown：未检索备案名单，记为未知；不推断是否备案。Filing registry not searched; recorded as unknown without inferring filing status.
备案信息以网信办《生成式人工智能服务已备案信息》公示名单为准（按批次滚动更新，本站只抄编号不解读）；「大陆可直连」是本站从大陆网络直连实测的结果，不是厂商承诺。GitHub 类站点当日实测有波动，口径写在依据里。Filing status is quoted from the CAC public registry (updated batch by batch; this site copies the number and does not interpret it). "Direct access" is this site's own reachability measurement from a mainland network, not a vendor promise. GitHub-hosted sites fluctuated on the measurement day — the note says so.

- 模型与开放条件Model & openness
Nav2 本身不是模型产品；官方 README 未列模型 provider 清单。策略或模型接入通常经用户代码与生态集成，本站记为模型/策略无关（本站判断，核验范围限 README）。
Nav2 is not a model product; the official README lists no model provider list. Policy or model integration usually goes through user code and ecosystem integrations; this site records it as model/policy-agnostic (site judgement, verification limited to README).
- 运行位置Where it runs
Nav2 以库/框架形态在本机进程中使用，通常经 Python/C++ 或 ROS 生态调用；不是托管云服务。具体安装与平台支持以官方 README/文档为准，本次未实测。
Nav2 is used as a library/framework in local processes, commonly via Python/C++ or the ROS ecosystem; it is not a hosted cloud service. Installation and platform support follow official README/docs and were not tested here.
- 本地文件Local files
Nav2 会读写本地配置、场景、模型或数据资产；文件权限与资产许可需用户自行核对。它不替用户管理训练数据版权或机器人工作区安全。
Nav2 reads and writes local configuration, scenes, models or data assets; file permissions and asset licences must be checked by the user. It does not manage training-data copyright or robot workspace safety for the user.
- 关机后的任务Tasks after shutdown
节点或训练进程可在后台运行；关机续跑、分布式与故障恢复不是本次核验范围，需按官方部署文档核对。
Nodes or training processes can run in the background; shutdown continuation, distribution and failure recovery are outside this verification scope and must be checked against official deployment docs.
- 工具与扩展Tools & extensions
Nav2 提供命令行、插件或生态接口（如 ROS 话题/服务、仿真插件、策略训练接口）。MCP 接入方式官方 README 未说明，记为未知。
Nav2 provides command-line, plugin or ecosystem interfaces (such as ROS topics/services, simulation plugins, policy-training interfaces). MCP integration is not stated in the official README and is recorded as unknown.
- 上下文与记忆Context & memory
不适用：Nav2 不是对话模型，没有 LLM 上下文窗口；状态由配置、场景、节点状态或训练 checkpoint 承载。
Not applicable: Nav2 is not a chat model and has no LLM context window; state is carried by configuration, scenes, node state or training checkpoints.
- 权限与限制Permissions & limits
权限跟随操作系统与运行环境；涉及机器人硬件时还要核对设备访问、网络与急停边界。官方 README 未给统一权限模型，本次未实测。
Permissions follow the operating system and runtime environment; with robot hardware, device access, network and emergency-stop boundaries also need checking. The official README gives no unified permission model, and this was not tested here.
- 适合什么任务Best for
适合：移动机器人自主导航与行为编排。 不适合：机械臂操作规划或非 ROS 系统。
Fit: mobile-robot navigation and behaviour orchestration. Not fit: unverified production deployment, safety certification or real-hardware guarantees.
头号误解Top misconception
- 以为导航栈开箱即适应所有底盘——控制器与代价图参数要调Assuming Nav2 provides model intelligence itself — it provides navigation stack infrastructure; policies or models come from user code and ecosystems.
- 把行为树当黑盒，忽略恢复行为与插件边界Assuming results transfer to real hardware without checks — reality gap, permissions and safety boundaries need separate verification.
