能力重点 · 核心项目 · 其他公开项目 · 开源项目贡献 · 工具与技术 · 工程记录

我做机器人系统软件，关注三件最不应该模糊的事：任务如何确定地执行、异常如何被证据定位、系统边界如何被验证。

能力重点

  • 确定性任务运行时： 用固定工作流、截止时间、取消/恢复语义和设备确认约束任务执行。
  • 跨层可观测性： 关联 ROS 2、Linux/eBPF 与 CAN 证据；证据不足时拒绝给出诊断结论。
  • 系统边界验证： 从 RISC-V 多 hart 隔离到故障探针，区分配置声明、软件证据与硬件证据。
  • 工程栈： C、C++、ROS 2、Linux、SocketCAN、eBPF、RISC-V；Python 主要用于编排、验证与工程工具。重视可复现测试和明确的验证边界。

核心项目

workbench-mobile-home-robot

面向移动家庭机器人的核心工作台：以证据优先的任务运行时约束动作边界，记录可回放事件，并在验证证据不足时 fail-closed。
Python · C · ANTLR · CSS

Embodied Agent Runtime

面向 ROS 2 的确定性任务运行时：使用固定工作流、嵌套 Action、截止时间、取消与恢复语义承接 AI 和感知输入，并提供设备桥接、任务历史与受限模型适配。

RoboTraceOpt

关联 RuntimeEvent、ROS 2 tracing 与 Linux 运行时证据，构建可审计的跨层诊断和受约束配置优化流程。

quard-star-riscv64-net

个人项目：面向 QEMU quard-star 的 RISC-V64 系统，包含 7-hart SMP 内核、独立 FreeRTOS trusted hart、Sv39、VirtIO、文件系统与自研 TCP/IP 链路；我编写 OpenSBI domain DTS 声明资源边界，并用自建 fault probe 验证 PMP 双向访问拒绝。

Build the boundary. Trace the failure. Keep the evidence.

Pinned Loading

  1. workbench-mobile-home-robot workbench-mobile-home-robot Public

    Evidence-first runtime for a wheeled mobile household robot with bounded actions, replayable events, and fail-closed verification.

    Python 124 4

  2. embodied-agent-runtime embodied-agent-runtime Public

    ROS 2 task runtime where cancel and device-ACK are non-bypassable: CAN send success and device confirmation are separate states. 11 packages, 40% test coverage.

    C++ 13

  3. quard-star-riscv64-net quard-star-riscv64-net Public

    RISC-V64 SMP OS in C (reimplemented from rCore's Rust design). 7+1 hart split with OpenSBI domains; bidirectional PMP denial verified by fault probes, not assumed.

    C 1

  4. RoboTraceOpt RoboTraceOpt Public

    Cross-layer evidence admission for ROS 2 latency: refuses to emit a root cause when evidence is incomplete, and blocks unreliable diagnoses from reaching config changes.

    Python 11

  5. ros2-apriltag-docking-demo ros2-apriltag-docking-demo Public

    AprilTag docking with 6 admission guards (including pose-jump with angle wrapping); Guard is re-evaluated during the active task, not just at start.

    Python 1

  6. ros2-control-vcan-motor-demo ros2-control-vcan-motor-demo Public
