# XR-RM75 双臂遥操作
|
||||
|
||||
本仓库是面向 **Ubuntu 22.04 + ROS2 Humble + PICO 4 Ultra + 睿尔曼 RM75** 的阶段一 XR 双臂遥操作项目。当前目标是先跑通一条低速、安全、可调试的闭环：
|
||||
基于 **Ubuntu 22.04、ROS2 Humble、PICO 4 Ultra 和睿尔曼 RM75** 的双臂 XR 遥操作
|
||||
工作空间，支持单臂/双臂 Mock 与真机控制，以及 MuJoCo 运动学显示。
|
||||
|
||||
> [!WARNING]
|
||||
> 真机命令会连接并控制机械臂。首次运行必须从 Mock 和单臂低速验证开始，确保急停
|
||||
> 可用且工作区无人。当前项目没有双臂碰撞检测或避障。
|
||||
|
||||
## 当前能力
|
||||
|
||||
- PICO/XR 双手柄 UDP 输入，相对位姿目标与 Placo QP 七关节控制。
|
||||
- 单臂/双臂 Mock 与真机、手柄/话题夹爪控制，以及只读 MuJoCo 双臂显示。
|
||||
- 工作空间/圆柱限位、速度限制、指令超时和安全慢停。
|
||||
- 统一 launch、Tkinter 启动面板、调试话题和 Mock 输入工具。
|
||||
|
||||
尚未完成：D405/D435 视频流、数据记录、相机标定、目标检测、双臂碰撞避障、任务级状态机，以及 PICO 与 ROS 的完整时间同步和状态回传。
|
||||
|
||||
## 系统架构
|
||||
|
||||
```text
|
||||
PICO/XR 双手柄 UDP JSON
|
||||
PICO / XRoboToolkit
|
||||

|
||||
-> xr_rm_input/udp_controller_receiver
|
||||
-> /xr/left_controller 与 /xr/right_controller
|

||||
-> Mock 或 RM75 rm_movej_canfd
|
||||
-> joint_states / 调试话题
|
||||
-> 可选 xr_rm_mujoco/dual_arm_simulator
|
||||
-> /xr_rm/<arm_name>/current_pose、raw_target_pose、target_pose、cmd_vel、target_clamped 调试话题
|
||||
```
|
||||
|
||||
当前控制方式是“手柄相对位姿 + 单步 QP”遥操作：按住 `grip` 时锁定当前手柄位姿和机械臂 TCP 位姿，之后根据手柄相对位移和相对旋转生成目标 TCP。姿态目标使用旋转矩阵和 SO(3) 最短路径完成死区、滤波与限速，不经过 RPY。每个控制周期执行一次 Placo QP，并通过 `rm_movej_canfd` 下发 7 个关节目标。松开 `grip`、UDP 或关节反馈超时、节点退出时会请求机械臂慢停。
|
||||
工作空间包含五个 ROS2 包：`xr_rm_input` 负责手柄输入，`xr_rm_interfaces` 定义消息，
|
||||
`xr_rm_teleop` 实现遥操作与真机适配，`xr_rm_bringup` 提供启动和配置，
|
||||
`xr_rm_mujoco` 负责只读运动学显示。
|
||||
|
||||
## 当前范围
|
||||
`single_arm_velocity_teleop` 每个实例只控制一台机械臂；双臂模式分别启动 `left_arm_teleop` 和 `right_arm_teleop`。
|
||||
|
||||
已完成：
|
||||
## 环境与构建
|
||||
|
||||
- PICO/XR 手柄 UDP 数据接收，并分发到左右手柄 ROS2 话题。
|
||||
- 通过统一的 `arm_debug.launch.py` 支持左臂、右臂、双臂的 mock 调试和真机调试。
|
||||
- 使用现有双臂 URDF 的 MuJoCo 运动学显示，可由 Mock 或真机反馈同步双臂姿态。
|
||||
- RM75 真机连接适配，包含关节反馈缓存、`rm_movej_canfd` 关节透传、安全速度/加速度配置、可选初始化点位移动。
|
||||
- Placo 0.9.4 RM75 QP 逆解；收到首帧有效关节反馈后才启用，求解失败时保留上一组有效关节目标。
|
||||
- 真机模式下，点击对应手柄 `trigger` 可切换并保持对应夹爪开/关状态。
|
||||
- Tkinter 启动面板 `launcher_ui.py`，用于现场快速启动、监控 topic、检查环境和清理进程。
|
||||
- XRoboToolkit bridge 读取左右手柄 pose、Grip、Trigger、摇杆和主副按键。
|
||||
|
||||
暂未完成：
|
||||
|
||||
- D405/D435 视频流、数据记录、相机标定和目标检测链路。
|
||||
- 双臂碰撞模型、任务级状态机、自动采摘策略。
|
||||
- PICO 端与 ROS 端的完整时间同步和状态回传。

```
|
||||
|
||||
真机模式还需要安装睿尔曼 Python API2。若未安装，mock 模式仍可正常使用；真机启动时会提示缺少 `Robotic_Arm` 包。
|
||||
遥操作和 MuJoCo 节点固定使用 `/home/robot/miniconda3/envs/xr/bin/python`，
|
||||
其中固定 Placo 0.9.4、Pinocchio 3.7.0、NumPy 2.2.6 和 MuJoCo 3.10.0；不要从
|
||||
用户或系统 Python 覆盖这些版本。
|
||||
|
||||
遥操作和 MuJoCo 节点固定由 `/home/robot/miniconda3/envs/xr/bin/python` 启动，并复用其中的 Python 3.10、Placo 0.9.4、Pinocchio 3.7.0、NumPy 2.2.6 和 MuJoCo 3.10.0。`ros2`、`colcon`、pytest 和 `udp_controller_receiver` 仍使用系统 Python。禁止通过 `pip --user`、`sudo pip` 或系统安装升级 Placo、Pinocchio、EigenPy 和 NumPy。
|
||||
真机模式另需睿尔曼 Python API2；Mock 模式不依赖厂商 SDK。
|
||||
|
||||
只读检查 Placo 版本：
|
||||
## 快速开始
|
||||
|
||||
以下命令均在 `/home/robot/WS_xr` 执行，并先 source ROS2 与 `install/setup.bash`。
|
||||
|
||||
### Mock
|
||||
|
||||
```bash
|
||||
/home/robot/miniconda3/envs/xr/bin/python -c \
|
||||
"import importlib.metadata; print(importlib.metadata.version('placo'))"
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=both use_mock:=true
|
||||
```
|
||||
|
||||
输出必须为 `0.9.4`。
|
||||
|
||||
同时检查 MuJoCo：
|
||||
另开终端发送模拟手柄数据：
|
||||
|
||||
```bash
|
||||
/home/robot/miniconda3/envs/xr/bin/python -c \
|
||||
"import mujoco; print(mujoco.__version__)"
|
||||
```
|
||||
|
||||
当前验证版本为 `3.10.0`。系统 pytest 会通过 `xr_rm_mujoco/test/conftest.py` 复用该固定 XR 环境中的 MuJoCo，因此新包可直接按 ROS2 标准方式测试：
|
||||
|
||||
```bash
|
||||
colcon test --packages-select xr_rm_mujoco --event-handlers console_direct+
|
||||
colcon test-result --verbose
|
||||
```
|
||||
|
||||
如果希望 `launcher_ui.py` 从任意目录找到工作空间，可以设置：
|
||||
|
||||
```bash
|
||||
export XR_RM_WS=/home/robot/WS_xr
|
||||
```
|
||||
|
||||
## 使用 launcher_ui.py 调试
|
||||
|
||||
推荐现场调试优先使用图形化启动面板。它会自动进入工作空间、source ROS2 与 `install/setup.bash`，并把每个命令放到独立终端中运行。
|
||||
|
||||
源码方式启动：
|
||||
|
||||
```bash
|
||||
cd /home/robot/WS_xr
|
||||
python3 src/xr_rm_bringup/tools/launcher_ui.py
|
||||
```
|
||||
|
||||
构建后也可以通过 ROS2 入口启动：
|
||||
|
||||
```bash
|
||||
source /opt/ros/humble/setup.bash
|
||||
source install/setup.bash
|
||||
ros2 run xr_rm_bringup launcher_ui
|
||||
```
|
||||
|
||||
面板顶部的 `Mode` 分为四类：
|
||||
|
||||
- `Simulation`：双臂 mock、XRoboToolkit bridge、双手 sample UDP 和 controller 频率监控。
|
||||
- `MuJoCo`：双臂 Mock/真机 MuJoCo launch、XRoboToolkit bridge 和 controller 频率监控；真机命令会连接两台 RM75。
|
||||
- `Real Hardware`：左右臂网络 ping、左臂/右臂/双臂真机 launch、XRoboToolkit bridge 和左右夹爪开合。
|
||||
- `Diagnostics`：`ros2 doctor --report`、四个核心包的 `ros2 pkg prefix`、controller 位置/频率监控。
|
||||
|
||||
常用按钮：
|
||||
|
||||
- `Run Selected`：运行当前选中的命令。双击列表项也可以运行。
|
||||
- `Check Env`：检查 ROS2 Humble、工作空间 build、终端、四个核心 ROS 包、睿尔曼 API2。
|
||||
- `Stop All`：结束由本工作空间启动的 launch、sample sender、topic monitor、MuJoCo viewer、相关 ROS 节点和终端窗口。
|
||||
|
||||
`Stop All` 会保留现有 PC Service；点击启动器窗口 `X` 并确认退出时会额外停止 PC Service。两条清理路径都会停止 `dual_arm_simulator`，关闭 MuJoCo viewer。
|
||||
|
||||
每个模式都会附带基础监控入口：
|
||||
|
||||
- `Open Controller Topic Monitor`：同时查看 `/xr/left_controller` 和 `/xr/right_controller`。
|
||||
- `Open ROS Topic/Node List Monitor`：每秒刷新 `ros2 topic list` 和 `ros2 node list`。
|
||||
|
||||
`Simulation` 和 `MuJoCo` 模式还提供 `Open Controller Hz Monitor`；`Diagnostics` 同时提供 controller 位置与频率监控。
|
||||
|
||||
分屏监控依赖 `x-terminal-emulator` 指向 Terminator。若提示不支持，可安装并切换：
|
||||
|
||||
```bash
|
||||
sudo apt install terminator wmctrl xdotool
|
||||
sudo update-alternatives --config x-terminal-emulator
|
||||
```
|
||||
|
||||
## 推荐调试顺序
|
||||
|
||||
第一步：检查环境。
|
||||
|
||||
打开 `launcher_ui.py`，点击 `Check Env`。如果 `install/setup.bash` 缺失，先回工作空间根目录重新执行 `colcon build --symlink-install`。
|
||||
|
||||
第二步：分别跑左、右臂 mock 闭环。
|
||||
|
||||
分两个终端依次验证左臂：
|
||||
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=left use_mock:=true
|
||||
ros2 run xr_rm_input sample_udp_sender --hand left --host 127.0.0.1 --port 15000 \
|
||||
ros2 run xr_rm_input sample_udp_sender \
|
||||
--hand both --host 127.0.0.1 --port 15000 \
|
||||
--pattern axis_sweep --seconds 30
|
||||
```
|
||||
|
||||
停止左臂进程后，再分别验证右臂：
|
||||
单臂调试时将 `arm` 改为 `left` 或 `right`。推荐先分别完成左右单臂
|
||||
Mock，再进入双臂或真机验证。
|
||||
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=right use_mock:=true
|
||||
ros2 run xr_rm_input sample_udp_sender --hand right --host 127.0.0.1 --port 15000 \
|
||||
--pattern axis_sweep --seconds 30
|
||||
```
|
||||
|
||||
`sample_udp_sender` 默认使用 `axis_sweep` 扫轴轨迹，并在终端打印 `XR +X/-X/+Y/-Y/+Z/-Z` 标签。需要检查末端姿态时可增加 `--rotation-pattern rpy_steps --rotation-amplitude-deg 25`。
|
||||
|
||||
观察：
|
||||
|
||||
```bash
|
||||
ros2 topic echo /xr/left_controller
|
||||
ros2 topic echo /xr/right_controller
|
||||
ros2 topic echo /xr_rm/left_rm75/target_pose
|
||||
ros2 topic echo /xr_rm/right_rm75/target_pose
|
||||
ros2 topic echo /xr_rm/left_rm75/cmd_vel
|
||||
ros2 topic echo /xr_rm/right_rm75/cmd_vel
|
||||
```
|
||||
|
||||
第三步：单臂真机。
|
||||
|
||||
先只上一个臂，确认网络、方向、急停和限幅：
|
||||
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=left use_mock:=false
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=right use_mock:=false
|
||||
```
|
||||
|
||||
所有 YAML 默认都不会执行 `movej(initial_joint_pose)`。只有确认安全区清空后，才可在当前使用的
|
||||
`left_arm_rm75.yaml`、`right_arm_rm75.yaml` 或 `dual_arm_rm75.yaml` 中将
|
||||
`move_to_initial_pose_on_connect` 改为 `true`。
|
||||
|
||||
第四步：双臂真机。
|
||||
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=both use_mock:=false
|
||||
```
|
||||
|
||||
双臂默认不会自动移动到初始化点；机器人地址、控制参数和初始化移动开关均从
|
||||
`dual_arm_rm75.yaml` 读取。
|
||||
|
||||
## Launch 入口说明
|
||||
|
||||
`arm_debug.launch.py` 是当前唯一的遥操作 launch 主入口，`launcher_ui.py` 中的 Simulation、MuJoCo 和 Real Hardware launch 命令都调用它。
|
||||
|
||||
常用参数：
|
||||
|
||||
- `arm`：`left`、`right`、`both`，默认 `right`。
|
||||
- `use_mock`：`true` 不连接真机，`false` 连接 RM75。
|
||||
- `use_mujoco`：`true` 额外启动双臂 MuJoCo 显示，默认 `false`，仅支持 `arm:=both`。
|
||||
- `udp_host`：UDP 监听地址，默认 `0.0.0.0`。
|
||||
- `udp_port`：UDP 监听端口，默认 `15000`。
|
||||
- `udp_timer_hz`：UDP receiver 轮询频率，默认 `200.0`。
|
||||
|
||||
机器人 IP/端口、控制频率、CANFD、限速、工具和初始化位姿等行为参数只由对应 YAML
|
||||
配置，launch 不再提供同名覆盖项。
|
||||
|
||||
## MuJoCo 双臂仿真
|
||||
|
||||
无真机时，由 Mock 关节状态驱动 MuJoCo：
|
||||
### MuJoCo
|
||||
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py \
|
||||
arm:=both use_mock:=true use_mujoco:=true
|
||||
```
|
||||
|
||||
连接真机时，由两台 RM75 的实际关节反馈同步 MuJoCo。下面命令会连接真机，执行前必须完成真机安全检查：
|
||||
MuJoCo 只订阅关节状态，不参与控制。真机显示可将 `use_mock` 改为 `false`，
|
||||
但该命令会同时连接两台 RM75。
|
||||
|
||||
### PICO 输入
|
||||
|
||||
只保留一个 UDP 输入源，然后启动 XRoboToolkit bridge：
|
||||
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py \
|
||||
arm:=both use_mock:=false use_mujoco:=true
|
||||
```
|
||||
|
||||
桌面 UI 的 `MuJoCo` 模式分别提供上述 Mock 和真机命令，并明确标记会连接真机的 `Dual Arm MuJoCo Real Hardware Launch`。
|
||||
|
||||
MuJoCo 只订阅当前关节状态，不参与控制，也不向真机下发指令：
|
||||
|
||||
- `/xr_rm/left_rm75/joint_states`、`/xr_rm/right_rm75/joint_states`：当前适配器反馈；Mock 与真机模式均按控制周期约 `90 Hz` 发布。真机底层原始反馈周期仍为 `5 ms`（约 `200 Hz`），由遥操作节点按 `90 Hz` 采样发布。
|
||||
- `/xr_rm/left_rm75/joint_target`、`/xr_rm/right_rm75/joint_target`：经 QP 和现有限制处理后的目标关节角，仅用于调试，MuJoCo 不订阅。
|
||||
- MuJoCo viewer 默认按 `dual_arm_mujoco.yaml` 中的 `60 Hz` 刷新。其初始姿态直接来自 `dual_arm_rm75.yaml` 的 `initial_joint_pose`，不会在 MuJoCo YAML 中重复保存。
|
||||
|
||||
Mock 模式的遥操作目标仍经过 `dual_arm_rm75.yaml` 中的工作空间、圆柱、线速度、角速度、关节速度/加速度、超时和停止限制。左手 X、右手 A 分别立即复位对应 Mock 机械臂；Grip 保持按下时，下一控制周期会重新锚定并继续遥操作。真机复位完成后仍需松开 Grip 才能恢复遥操作，且 `move_to_initial_pose_on_connect` 保持为 `false`，连接真机不会自动移动。
|
||||
|
||||
## 配置文件说明
|
||||
|
||||
`xr_rm_bringup/config/dual_arm_rm75.yaml` 是双臂配置主文件，包含两个 ROS 节点命名空间：
|
||||
|
||||
- `left_arm_teleop`
|
||||
- `right_arm_teleop`
|
||||
|
||||
`left_arm_rm75.yaml` 和 `right_arm_rm75.yaml` 用于 `arm_debug.launch.py arm:=left/right` 的单臂调试，因为单臂节点名是 `single_arm_velocity_teleop`。
|
||||
|
||||
`dual_arm_mujoco.yaml` 只保存 MuJoCo viewer 刷新频率；双臂初始关节角和遥操作限制继续统一读取 `dual_arm_rm75.yaml`。
|
||||
|
||||
`xr_rm_bringup/config/peripherals_rm75.yaml` 保存真实控制器使用的末端工具坐标、负载和左右臂外设选择。左臂 `scissorgripper: 2` 是外设选择值，选择 `minisci`，TCP 的 Z 向偏移为 `0.165 m`；右臂 `scissorgripper: 1`，选择 `omnipic`，TCP 的 Z 向偏移为 `0.14 m`。真机连接阶段仍会初始化外设，关节反馈、关节指令、慢停和开合命令复用该单臂节点的同一个 RealMan 连接。
|
||||
|
||||
Placo 使用 `xr_rm_teleop/models/dual_rm75/Dual_arm.urdf`。左右 ROS 节点分别创建独立 solver：左臂从 `scissor_base_link` 到 `scissor_scissor_tcp`，并 mask 右臂；右臂从 `omnipic_base_link` 到 `omnipic_OmniPic_tcp`，并 mask 左臂。节点目标仍在各自局部基坐标系中，现有 PICO 映射不改为公共坐标系。
|
||||
|
||||
重点控制参数：
|
||||
|
||||
- `controller_topic`：订阅的手柄话题。
|
||||
- `scale`：手柄位移到 TCP 位移的比例。
|
||||
- `target_filter_alpha` / `target_filter_alpha_fast`：目标 TCP 低通滤波系数，快速移动时自动使用更大的系数。
|
||||
- `target_filter_fast_threshold_m`：进入快速滤波区间的目标变化阈值。
|
||||
- `max_linear_speed`：目标位姿单帧步长限制对应的最大线速度。
|
||||
- `enable_orientation_control`：是否把手柄相对旋转映射到 TCP 姿态。
|
||||
- `orientation_filter_alpha` / `orientation_deadband_rad`：按 SO(3) 最短旋转角处理的目标 TCP 姿态滤波和死区。
|
||||
- `max_orientation_speed`：目标 TCP 姿态沿 SO(3) 最短路径的最大角速度，当前为 `0.5 rad/s`。
|
||||
- `workspace_min` / `workspace_max`：笛卡尔工作空间边界。
|
||||
- `cyl_radius_limit`：基座圆柱半径限制。
|
||||
- `xr_to_robot_matrix`：`/xr/*_controller` Project 位移到 RM75 base 坐标的映射矩阵。
|
||||
- `robot_ip` / `robot_port`：RM75 TCP 控制连接地址。
|
||||
- `realtime_push_host_ip`：连接机械臂 Wi-Fi 后本机实际 IPv4；可用
|
||||
`ip -4 route get 192.168.192.19` 查看输出中的 `src`，当前为 `192.168.192.148`。
|
||||
- `realtime_push_port`：UDP 主动反馈端口；左臂 `8089`、右臂 `8090`，同机双臂不能重复。
|
||||
- `realtime_push_cycle_ms`：UDP 主动反馈周期，当前为厂商支持的 `5 ms`。
|
||||
- `follow` / `canfd_trajectory_mode`：`rm_movej_canfd` 的高跟随和轨迹模式参数。
|
||||
- 当前三份 YAML 默认均使用 `follow: false` 完成安全基线验证；确认关节加速度与反馈稳定后，再单独测试高跟随。
|
||||
- `initial_joint_pose`：mock 的初始关节反馈，以及显式开启初始化移动时的真机初始关节角。
|
||||
|
||||
当前 `/xr/*_controller` 的坐标处理：
|
||||
|
||||
- XRoboToolkit bridge 原样转发 SDK 的手柄位置和四元数，不额外转换坐标轴。
|
||||
- receiver 默认按 `xyzw` 解析四元数，也可通过 `quat_order:=wxyz` 切换。
|
||||
- 左臂映射：机器人位移增量 = `[-手柄y, 手柄z, -手柄x]`。
|
||||
- 右臂映射：机器人位移增量 = `[手柄y, 手柄z, 手柄x]`。
|
||||
- 两侧局部 `-Y` 均指向机器人前方；局部 `+Y` 指向后方，后方工作空间仅保留 `0.10 m`。
|
||||
- 左臂局部 `+X/+Y/+Z` 分别指向下/后/左外侧；右臂分别指向上/后/右外侧。
|
||||
|
||||
如果某个机械臂方向相反，只改对应臂的 `xr_to_robot_matrix` 符号，不要同时改多个控制参数。
|
||||
|
||||
## 末端工具开合
|
||||
|
||||
真机 launch 默认会在遥操作节点内启用工具控制。左/右手柄 `trigger` 从低于阈值按到 `>= 0.95` 时，会切换一次对应夹爪开/关状态，并保持到下一次点击。`grip` 仍只控制机械臂运动，不影响夹爪 trigger 切换。
|
||||
|
||||
也可以用 Bool 话题手动控制开合，`true` 表示打开，`false` 表示闭合：
|
||||
|
||||
```bash
|
||||
ros2 topic pub --once /xr_rm/left_rm75/tool_enable std_msgs/msg/Bool "{data: true}"
|
||||
ros2 topic pub --once /xr_rm/left_rm75/tool_enable std_msgs/msg/Bool "{data: false}"
|
||||
|
||||
ros2 topic pub --once /xr_rm/right_rm75/tool_enable std_msgs/msg/Bool "{data: true}"
|
||||
ros2 topic pub --once /xr_rm/right_rm75/tool_enable std_msgs/msg/Bool "{data: false}"
|
||||
```
|
||||
|
||||
桌面 UI 的 `Real Hardware` 模式提供 `Left/Right Gripper Open/Close` 命令项；运行双臂真机 launch 时也可直接通过左右手柄 `trigger` 分别切换夹爪。
|
||||
|
||||
## UDP 数据格式
|
||||
|
||||
当前 XRoboToolkit bridge 每个周期发送一个双手柄 JSON 包：
|
||||
|
||||
```json
|
||||
{
|
||||
"t": 12.345,
|
||||
"source_time": 12.345,
|
||||
"seq": 42,
|
||||
"frame_id": "xr_world",
|
||||
"controllers": {
|
||||
"left": {
|
||||
"hand": "left",
|
||||
"grip": true,
|
||||
"trigger": 0.0,
|
||||
"axis": [0.2, -0.4],
|
||||
"buttons": {
|
||||
"primary": true,
|
||||
"secondary": false
|
||||
},
|
||||
"pos": [-0.12, 1.05, 0.30],
|
||||
"quat": [0.0, 0.0, 0.0, 1.0],
|
||||
"pose_valid": true,
|
||||
"pose_source": "xrobotoolkit"
|
||||
},
|
||||
"right": {
|
||||
"hand": "right",
|
||||
"grip": true,
|
||||
"trigger": 1.0,
|
||||
"axis": [-0.1, 0.3],
|
||||
"buttons": {
|
||||
"primary": false,
|
||||
"secondary": true
|
||||
},
|
||||
"pos": [0.12, 1.05, 0.30],
|
||||
"quat": [0.0, 0.0, 0.0, 1.0],
|
||||
"pose_valid": true,
|
||||
"pose_source": "xrobotoolkit"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
字段说明：
|
||||
|
||||
- `t` / `source_time`：bridge 的 PC 单调时间，用于诊断发送周期。
|
||||
- `seq`：bridge 递增的 UDP 包序号，bridge 重启后重新计数。
|
||||
- `frame_id`：默认 `xr_world`，会写入 `XrController.header.frame_id`。
|
||||
- `grip`：运动使能。`true` 时进入相对位姿控制，`false` 时停止。
|
||||
- `trigger`：经过 bridge 滞回处理的 `0.0/1.0` 值；上升沿切换对应夹爪状态。
|
||||
- `axis`：摇杆 `[x, y]`，每个分量限制在 `-1.0` 到 `1.0`。
|
||||
- `buttons.primary`：左手 X 键或右手 A 键。
|
||||
- `buttons.secondary`：左手 Y 键或右手 B 键。
|
||||
- `pos`：手柄位置，长度 3。
|
||||
- `quat`：手柄姿态四元数，默认按 `xyzw` 解析。
|
||||
- `pose_valid`：姿态是否可信；`false` 时接收端强制 `grip=false`。
|
||||
- `pose_source`：当前 bridge 使用 `xrobotoolkit`。
|
||||
|
||||
`axis`、`buttons.primary` 和 `buttons.secondary` 会进入 `XrController`；旧 UDP
|
||||
包缺少这些字段时分别回退为 `[0,0]`、`false` 和 `false`。
|
||||
|
||||
接收端发布的消息格式为：
|
||||
|
||||
```text
|
||||
std_msgs/Header header
|
||||
string hand
|
||||
|
||||
bool grip
|
||||
float32 trigger
|
||||
bool primary
|
||||
bool secondary
|
||||
float32[2] axis
|
||||
|
||||
geometry_msgs/Pose pose
|
||||
```
|
||||
|
||||
`udp_controller_receiver` 仍兼容调试用的单手柄包：可以直接发送带 `hand`、`pos`、
|
||||
`quat` 的 JSON object，也可以用 `controllers` list、顶层 `left/right`、
|
||||
`pose.position`、`position`、`p`、`q` 等常见字段。
|
||||
|
||||
## 官方 XRoboToolkit bridge
|
||||
|
||||
如果使用官方 XRoboToolkit APK 和 PC-Service，可以用 `xrobotoolkit_to_udp_bridge` 从本机 ROS Python 环境中的 `xrobotoolkit_sdk` 读取左右手柄数据，再转换成当前 `udp_controller_receiver` 支持的 UDP JSON。
|
||||
|
||||
正式运行时不要同时启动官方 `PXREAClientUnity` / `RobotLinuxDemo` 可视化窗口。`/opt/apps/roboticsservice/run3D.sh` 会启动这个可视化 demo，适合单独确认 PICO 与 PC-Service 已连接；bridge 遥操作链路中只需要 PC-Service。
|
||||
|
||||
运行前只保留一个 UDP 输入源。先清掉重复 bridge、sample sender 和官方 Unity 可视化 demo，再保留或启动 PC-Service：
|
||||
|
||||
```bash
|
||||
pkill -f '[x]robotoolkit_to_udp_bridge'
|
||||
pkill -f '[s]ample_udp_sender'
|
||||
pkill -f '[R]obotLinuxDemo.x86_64'
|
||||
pkill -f '[P]XREAClientUnity'
|
||||
pgrep -af RoboticsServiceProcess || /opt/apps/roboticsservice/runService.sh
|
||||
```
|
||||
|
||||
启动 ROS mock 接收链路：
|
||||
|
||||
```bash
|
||||
cd /home/robot/WS_xr
|
||||
source /opt/ros/humble/setup.bash
|
||||
source install/setup.bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=both use_mock:=true
|
||||
```
|
||||
|
||||
另开终端启动 bridge：
|
||||
|
||||
```bash
|
||||
cd /home/robot/WS_xr
|
||||
source ~/.bashrc
|
||||
source /opt/ros/humble/setup.bash
|
||||
source install/setup.bash
|
||||
ros2 run xr_rm_input xrobotoolkit_to_udp_bridge \
|
||||
--host 127.0.0.1 --port 15000 --hz 90
|
||||
```
|
||||
|
||||
bridge 默认对 grip/trigger 做轻量滞回：`grip` 按下阈值 `0.90`、松开阈值 `0.75`；`trigger` 按下阈值 `0.95`、松开阈值 `0.75`。启动日志会打印 PID、UDP endpoint 和阈值，便于确认当前只运行了一个 bridge。
|
||||
|
||||
验证手柄数据是否进入 ROS：
|
||||
确认左右 topic 持续接收数据：
|
||||
|
||||
```bash
|
||||
ps -ef | grep -E 'xrobotoolkit_to_udp_bridge|sample_udp_sender|RobotLinuxDemo|PXREAClientUnity' | grep -v grep
|
||||
ros2 topic hz /xr/left_controller
|
||||
ros2 topic hz /xr/right_controller
|
||||
ros2 topic echo /xr/left_controller --field pose.position
|
||||
ros2 topic echo /xr/right_controller --field pose.position
|
||||
ros2 topic echo /xr/left_controller --field grip
|
||||
ros2 topic echo /xr/right_controller --field grip
|
||||
ros2 topic echo /xr/right_controller --field trigger
|
||||
```
|
||||
|
||||
`/xr/left_controller` 和 `/xr/right_controller` 持续刷新、位置随手柄移动变化、`grip` 随握持键切换，即表示官方 XRoboToolkit 数据已经进入当前遥操作输入层。
|
||||
图形启动面板可运行 `python3 src/xr_rm_bringup/tools/launcher_ui.py`，提供
|
||||
Simulation、MuJoCo、Real Hardware 和 Diagnostics 模式。
|
||||
|
||||
## 真机安全验证
|
||||
### 真机
|
||||
|
||||
第一次接真机时按这个顺序走：
|
||||
确认对应 YAML 中 `move_to_initial_pose_on_connect: false`，再从单臂开始：
|
||||
|
||||
1. 确认急停、网络、机械臂工作区和人员位置。
|
||||
2. `launcher_ui.py` 中先 `Ping Left RM75` 或 `Ping Right RM75`。
|
||||
3. 确认对应 YAML 中 `move_to_initial_pose_on_connect: false` 后单臂启动。
|
||||
4. 手握急停，按住 `grip` 后只做小幅单轴移动。
|
||||
5. 逐个确认上/下、前/后、左/右方向。
|
||||
6. 小角度转动手柄，确认 `/xr_rm/<arm>/target_pose` 姿态和 `/xr_rm/<arm>/cmd_vel.twist.angular` 变化符合预期。
|
||||
7. 点击对应 `trigger`，确认每次点击都会切换对应夹爪状态，松开 trigger 后状态保持且左右不串臂。
|
||||
8. 确认松开 `grip` 后机械臂慢停，`/xr_rm/<arm>/cmd_vel` 回到零；trigger 仍只影响夹爪，不影响机械臂运动门控。
|
||||
9. 左右臂都确认后，再运行 `Dual Arm RealMan Launch`。
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=left use_mock:=false
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=right use_mock:=false
|
||||
```
|
||||
|
||||
当前项目没有双臂碰撞检测/避障。双臂首次联调时，请让两个工作区在物理上分开，低速验证，不要让两臂末端互相靠近。
|
||||
单臂方向、限位、急停、超时停止和夹爪均验证后，才能启动双臂：
|
||||
|
||||
## 后续优化路线
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py arm:=both use_mock:=false
|
||||
```
|
||||
|
||||
为了达到“稳定可用的双臂 XR 遥操作/采摘平台”，建议按下面顺序推进：
|
||||
按住 `grip` 控制对应机械臂；松开后停止。点击 `trigger` 切换对应夹爪开/关。
|
||||
左手 X、右手 A 会请求对应机械臂回到配置的初始位姿；真机使用前必须清空安全区。
|
||||
|
||||
1. 稳定 PICO 数据链路：利用 `seq`、`source_time`、`pose_valid` 做频率、延迟、丢包和追踪状态统计，记录 `/xr/*_controller`、`/xr_rm/*/raw_target_pose`、`/xr_rm/*/target_pose`、`/xr_rm/*/target_clamped`、`/xr_rm/*/current_pose`。
|
||||
2. 提升真机安全性：增加启动前安全检查、软件急停 topic、UI Stop 状态提示、双臂中间区域互斥边界和速度/加速度限幅。
|
||||
3. 细化末端执行器：增加夹爪状态反馈、力控比例、安全上限和现场可视化提示。
|
||||
4. 接入视觉和数据记录：加入 D405/D435 相机 launch、TF、内外参和 rosbag2 实验记录。
|
||||
5. 从遥操作走向半自动：先做目标检测和 3D 定位提示，再做单臂辅助，最后做双臂任务分配和任务级状态机。
|
||||
## Launch 参数
|
||||
|
||||
## 常见问题
|
||||
统一入口为 `xr_rm_bringup/launch/arm_debug.launch.py`：
|
||||
|
||||
`launcher_ui.py` 提示找不到 `install/setup.bash`：
|
||||
| 参数 | 默认值 | 说明 |
|
||||
| --- | --- | --- |
|
||||
| `arm` | `right` | `left`、`right` 或 `both` |
|
||||
| `use_mock` | `true` | `false` 会连接真机 |
|
||||
| `use_mujoco` | `false` | 仅支持 `arm:=both` |
|
||||
| `udp_host` | `0.0.0.0` | UDP 监听地址 |
|
||||
| `udp_port` | `15000` | UDP 监听端口 |
|
||||
| `udp_timer_hz` | `200.0` | UDP receiver 轮询频率 |
|
||||
|
||||
## 配置
|
||||
|
||||
| 文件 | 用途 |
|
||||
| --- | --- |
|
||||
| `dual_arm_rm75.yaml` | 双臂节点、网络、控制与安全参数 |
|
||||
| `left_arm_rm75.yaml` | 左臂单独调试 |
|
||||
| `right_arm_rm75.yaml` | 右臂单独调试 |
|
||||
| `peripherals_rm75.yaml` | 工具坐标、负载和末端执行器 |
|
||||
| `dual_arm_mujoco.yaml` | MuJoCo 刷新频率 |
|
||||
|
||||
修改某一侧控制参数时，同时检查单臂和双臂 YAML 是否需要同步。必须保留工作空间/
|
||||
圆柱限位、线速度与角速度限制、关节速度/加速度限制、指令超时和安全停止逻辑。
|
||||
|
||||
`configure_safety_limits` 不得默认关闭；
|
||||
`move_to_initial_pose_on_connect` 必须保持默认 `false`。
|
||||
|
||||
## 测试
|
||||
|
||||
在工作空间根目录执行：
|
||||
|
||||
```bash
|
||||
cd /home/robot/WS_xr
|
||||
source /opt/ros/humble/setup.bash
|
||||
colcon build --symlink-install
|
||||
source install/setup.bash
|
||||
colcon test --event-handlers console_direct+
|
||||
colcon test-result --verbose
|
||||
```
|
||||
|
||||
真机模式提示缺少 `Robotic_Arm`：
|
||||
涉及遥操作姿态控制时，额外运行：
|
||||
|
||||
```text
|
||||
未安装睿尔曼 Python API2。请安装厂商 SDK，或用 use_mock:=true 先跑模拟模式。
|
||||
```bash
|
||||
pytest src/xr_rm_teleop/test/test_orientation_control.py
|
||||
```
|
||||
|
||||
Controller topic 没有数据：
|
||||
|
||||
- 确认 UDP 发送端目标 IP 是运行 ROS2 的主机 IP。
|
||||
- 确认端口是 `15000`，或 launch 与发送端端口一致。
|
||||
- 用 `sample_udp_sender` 在本机验证接收链路。
|
||||
- 确认 `xrobotoolkit_to_udp_bridge` 没有持续打印 SDK read failed；SDK
|
||||
读取失败时 bridge 会发送 `pose_valid=false` 的停止包。
|
||||
|
||||
机械臂不动：
|
||||
|
||||
- 确认 `grip=true`。
|
||||
- 确认 `udp_controller_receiver` 终端没有持续 `pose_valid=false` 日志；该字段不会写入 `XrController` 消息，但会让接收端强制停止。
|
||||
- 确认 `/xr_rm/<arm>/raw_target_pose` 与 `/xr_rm/<arm>/target_pose` 是否在变化。
|
||||
- 确认 `/xr_rm/<arm>/target_clamped` 是否持续为 `true`，如果是，目标 TCP 可能被工作空间、圆柱半径或单帧步长限制夹住。
|
||||
- 确认真机 SDK 连接成功，且 RM75 没有报警或急停。
|
||||
真机验证不属于自动测试。默认使用 `use_mock:=true`，未经现场安全确认不要连接或
|
||||
移动机械臂。

# 右臂番茄采摘 ACT 数据采集适配设计
|
||||
|
||||
## 背景与目标
|
||||
|
||||
当前项目已经通过 ROS2 Humble、PICO 手柄、Placo QP 和 RealMan Python API2
|
||||
完成 RM75 遥操作。右臂遥操节点以名义 `90 Hz` 读取实际关节反馈，根据 PICO
|
||||
相对位姿生成 TCP 目标，经过工作空间限制、QP、关节速度与加速度限制后，通过
|
||||
`rm_movej_canfd` 下发最终关节目标。
|
||||
|
||||
本次变更在不重写现有遥操链路的前提下，增加一个独立的 ALOHA/ACT 风格数据采集
|
||||
节点。第一阶段只采集右臂番茄采摘任务，每个 episode 覆盖从初始位姿出发、抓取
|
||||
番茄、搬运至 RM75 下方收集篮并释放番茄的完整过程。
|
||||
|
||||
核心目标如下：
|
||||
|
||||
- 以右臂 7 个实际关节角和夹爪逻辑状态作为 `observations/qpos`；
|
||||
- 以实际成功下发或零阶保持的 7 个最终关节目标和夹爪目标作为 `action`；
|
||||
- 同步采集一台全局 D455 和一台右腕 D405 的 RGB 图像；
|
||||
- 以 `30 Hz` 形成同周期因果对齐的数据；
|
||||
- 每个完整任务流式保存为一个 ALOHA/ACT 核心结构兼容的 HDF5 文件；
|
||||
- 支持手柄开始、结束、丢弃、拒绝、质量检查、崩溃恢复和编号防覆盖；
|
||||
- 保留足够的 PICO、TCP、QP、夹爪和时间戳调试数据，但不让采集节点进入机器人
|
||||
控制链路。
|
||||
|
||||
参考实现为 ALOHA 官方仓库中的
|
||||
[`record_episodes.py`](https://github.com/tonyzhaozh/aloha/blob/master/aloha_scripts/record_episodes.py)。
|
||||
官方双臂数据使用 14 维状态和动作；本项目第一阶段采用右臂 `7+1=8` 维，因此只
|
||||
保证 HDF5 核心组织方式兼容，不声称官方旧训练加载器可以不修改直接训练。
|
||||
|
||||
## 非目标
|
||||
|
||||
第一阶段明确不实现：
|
||||
|
||||
- 左臂或双臂 ACT 采集；
|
||||
- ACT 训练代码、数据加载器、策略部署或自动完成判定；
|
||||
- 深度图、红外图、点云、图像压缩或 ROS 图像话题；
|
||||
- rosbag、中间格式、离线转换工具、GUI、声音或手柄震动反馈；
|
||||
- 让 ACT 学习 A 键触发的回初始位姿运动；
|
||||
- 修改现有工作空间限制、圆柱限制、速度限制、指令超时、安全停止或
|
||||
`move_to_initial_pose_on_connect` 默认值；
|
||||
- 新建重复的 ROS2 包或第二个 RealMan 连接。
|
||||
|
||||
后续训练时建议将 ACT `chunk_size` 设为 `60`，对应约 2 秒动作长度；该参数属于
|
||||
训练配置，不写死在采集逻辑中。
|
||||
|
||||
## 现有控制链路与关键约束
|
||||
|
||||
现有 `single_arm_velocity_teleop` 在每个控制周期内依次完成：
|
||||
|
||||
```text
|
||||
读取最新 RM75 反馈
|
||||
→ 同步 Placo 状态
|
||||
→ 读取 PICO 状态并生成 TCP 目标
|
||||
→ 工作空间、位姿步长与速度限制
|
||||
→ Placo QP
|
||||
→ 关节速度与加速度限制
|
||||
→ rm_movej_canfd 下发
|
||||
→ 发布 joint_target 调试话题
|
||||
```
|
||||
|
||||
当前 `joint_states`、TCP 调试话题和 `joint_target` 分别发布并各自取时间戳。如果
|
||||
采集节点仅订阅这些分散话题，即使时间接近，也可能把第 100 个控制周期的
|
||||
`q_actual` 与第 99 个控制周期的 `q_target` 拼在一起。这里的“第 100 个周期”是
|
||||
控制序号，不是 `100 Hz`；现有控制频率仍是名义 `90 Hz`。
|
||||
|
||||
此外，A 键回位调用的是一次阻塞式 `rm_movej(initial_joint_pose)`。轨迹由 RM75
|
||||
控制器内部生成，项目不能获得每个控制周期的中间目标，也不经过当前 QP 和
|
||||
`rm_movej_canfd` 链路，因此不能与遥操动作混用同一种标签语义。
|
||||
|
||||
## 总体架构
|
||||
|
||||
采用一个自定义原子控制采样消息和一个独立 ACT 采集节点：
|
||||
|
||||
```text
|
||||
PICO 输入 + RM75 反馈
|
||||
↓
|
||||
single_arm_velocity_teleop（90 Hz）
|
||||
↓
|
||||
QP → 关节限速/限加速度 → RM75 下发
|
||||
↓
|
||||
ActControlSample（同周期、同时间戳、同序号）
|
||||
↓
|
||||
act_episode_recorder（每 3 个控制周期取 1 个）
|
||||
├──────────────┐
|
||||
↓ ↓
|
||||
全局 D455 RGB 右腕 D405 RGB
|
||||
└──────┬───────┘
|
||||
↓
|
||||
30 Hz 流式写入临时 HDF5
|
||||
↓
|
||||
裁剪 → 质量检查 → 保存/拒绝/丢弃
|
||||
```
|
||||
|
||||
“原子”表示消息是一个逻辑上不可拆分的控制周期快照。订阅者要么收到该周期完整的
|
||||
反馈、求解结果、最终动作和状态，要么该周期整体缺失；不会自行拼接多个异步话题。
|
||||
|
||||
职责边界如下：
|
||||
|
||||
- 遥操节点继续唯一负责 RM75 连接、反馈、QP、限位、动作下发和安全停止；
|
||||
- 遥操节点只增加原子消息发布和夹爪逻辑状态记录，不读取相机、不写 HDF5；
|
||||
- 采集节点只订阅控制/PICO 数据、独占两台相机并写文件，不连接或控制 RM75；
|
||||
- 采集节点异常、退出或写盘过慢不得阻塞遥操发布或改变机器人动作；
|
||||
- 相机由采集节点通过 `pyrealsense2` 直接打开，不再发布和重新订阅 ROS 图像。
|
||||
|
||||
原子消息使用本机低延迟、非阻塞的 best-effort QoS。采集节点检测任何需要保留的
|
||||
控制周期丢失并拒绝 episode，而不是让 DDS 反压影响遥操控制。
|
||||
|
||||
## 原子控制采样消息
|
||||
|
||||
在 `xr_rm_interfaces` 中新增 `ActControlSample.msg`，发布话题为：
|
||||
|
||||
```text
|
||||
/xr_rm/right_rm75/act_control_sample
|
||||
```
|
||||
|
||||
消息至少表达以下内容：
|
||||
|
||||
| 类别 | 字段语义 |
|
||||
|---|---|
|
||||
| 周期标识 | ROS header、`control_seq`、控制周期单调时间戳 |
|
||||
| 关节反馈 | `q_actual[7]`、当前 URDF 关节上下限、反馈接收单调时间戳、反馈年龄、反馈有效状态 |
|
||||
| QP | QP 原始输出或失败时的保持目标 `q_qp_raw[7]`、是否尝试、成功状态、耗时 |
|
||||
| 最终动作 | 经关节限速后的 `q_target[7]`、动作时间戳、是否当前周期成功下发 |
|
||||
| TCP | 当前 TCP、PICO 映射前的原始目标 TCP、最终受限目标 TCP、命令速度 |
|
||||
| PICO | 当前右手位姿、Grip、Trigger、A、B 和摇杆值 |
|
||||
| 夹爪 | 请求目标、已确认逻辑状态、命令是否处理中、命令是否失败 |
|
||||
| 控制状态 | `teleop_active`、`action_valid`、QP 回退、目标限位和控制故障状态 |
|
||||
|
||||
数值型关节字段在 ROS 消息中保持双精度，写入 HDF5 核心数据时显式转换成
|
||||
`float32`。位姿使用位置加四元数，不保存完整 Placo 对象、Hessian、约束矩阵或
|
||||
其他大体积求解器内部状态。
|
||||
|
||||
消息在每个实际执行的 90 Hz 控制回调中发布，包括 Grip 松开和安全停止状态：
|
||||
|
||||
- 当前周期成功发送动作时，`command_sent=true`；
|
||||
- 当前周期没有发送，但此前存在成功目标时，`q_target` 零阶保持上一个成功目标，
|
||||
`command_sent=false`、`action_valid=true`；
|
||||
- 尚未形成任何有效目标或当前动作发送失败时，`action_valid=false`；
|
||||
- QP 失败但成功重发上次有效目标时，`qp_success=false`、`action_valid=true`；
|
||||
- 发送失败必须发布失败状态，并由采集节点拒绝当前 episode。
|
||||
|
||||
相机数据不放进该消息。相机时间戳和帧号由采集节点在同一主机的单调时钟域中补充。
|
||||
|
||||
## 夹爪数据语义
|
||||
|
||||
右臂使用 Modbus 电动夹爪。由于不同番茄尺寸会导致实际停止开度不同，而本项目只
|
||||
关心抓取意图，第一阶段不读取或估算实际开度。
|
||||
|
||||
统一约定：
|
||||
|
||||
```text
|
||||
0 = closed
|
||||
1 = open
|
||||
```
|
||||
|
||||
两类状态必须分开：
|
||||
|
||||
- `action[7]` 是目标状态，在 Trigger 产生开合请求的控制周期立即改变；
|
||||
- `qpos[7]` 是已确认逻辑状态，只有 Modbus 命令正常返回后才改变；
|
||||
- 命令失败时 `qpos[7]` 保持原值，并拒绝当前 episode；
|
||||
- 采集前右臂夹爪必须成功初始化为完全打开 `1.0`，之后才允许把初始
|
||||
`qpos[7]` 设为 `1`；
|
||||
- 不再使用原先含义不明确的 `0.75 → 0.15` 初始化序列。
|
||||
|
||||
结束一个有效番茄采摘 episode 前，操作者应先请求打开夹爪，等待日志/状态确认
|
||||
逻辑状态已经变为 `open`，再松开 Grip 并按 B。结束时夹爪命令仍在执行，保存状态
|
||||
最多等待 3 秒；失败或超时则拒绝。最终裁剪后的数据若没有包含已确认的打开状态，
|
||||
同样拒绝，不能把保存后的成功状态回填到更早样本中。
|
||||
|
||||
## 相机配置与采集
|
||||
|
||||
第一阶段固定使用两台已确定序列号的 RealSense：
|
||||
|
||||
| ACT 名称 | 型号与位置 | 序列号 |
|
||||
|---|---|---|
|
||||
| `cam_high` | 全局 D455 | `234222303366` |
|
||||
| `cam_right_wrist` | 右臂腕部 D405 | `412622272532` |
|
||||
|
||||
两路图像参数统一为：
|
||||
|
||||
```text
|
||||
分辨率：640 × 480
|
||||
帧率：30 FPS
|
||||
格式：RGB uint8
|
||||
HDF5 形状：(T, 480, 640, 3)
|
||||
```
|
||||
|
||||
不采集深度、红外和点云，不使用 JPEG 压缩。采集线程直接请求 RealSense RGB8，
|
||||
避免为颜色通道转换引入 OpenCV 依赖。
|
||||
|
||||
每台相机使用独立采集线程和一个很小的 `deque` 帧缓冲。每帧保存：
|
||||
|
||||
- RealSense 帧号；
|
||||
- RealSense 硬件时间戳；
|
||||
- `wait_for_frames` 返回后立即读取的主机单调时间戳；
|
||||
- RGB 数组。
|
||||
|
||||
两台设备的硬件时钟不能默认视为同一时钟域，因此正式对齐只使用同一主机的单调
|
||||
时钟；硬件时间戳只用于发现设备重启、帧号跳变和采集异常。
|
||||
|
||||
采集节点独占相机。指定设备缺失、型号/序列号不匹配、流配置失败或已经被其他
|
||||
进程占用时，预检失败并停留在 `IDLE`，不自动替换成其他相机。
|
||||
|
||||
## 30 Hz 采样与因果对齐
|
||||
|
||||
正式采样不使用独立的 30 Hz ROS 定时器。采集节点在首次有效 Grip 控制周期记录
|
||||
`sample_origin_seq`，随后只选择：
|
||||
|
||||
```text
|
||||
(control_seq - sample_origin_seq) % 3 == 0
|
||||
```
|
||||
|
||||
因此 90 Hz 控制消息按 `0、3、6、9...` 的相对序号形成名义 30 Hz 数据，同时保证
|
||||
第一个正式样本就是首次有效动作，而不是等待一个全局取模相位。
|
||||
|
||||
每个样本的定义为：
|
||||
|
||||
```text
|
||||
observation[t]
|
||||
= 当前控制周期开始时读取的 q_actual
|
||||
+ 对每台相机选择主机时间戳不晚于该控制周期的最新帧
|
||||
|
||||
action[t]
|
||||
= 同一控制周期经 QP、关节限速后成功发送的 q_target
|
||||
或 Grip 暂停/QP 回退时明确定义的上次成功目标
|
||||
```
|
||||
|
||||
采集节点收到消息时，相机缓冲中可能已经存在晚于控制周期的帧，因此不能简单取
|
||||
“回调时最新帧”，必须按 `host_monotonic_ns <= control_monotonic_ns` 选择最近帧。
|
||||
不存在满足条件且年龄不超过 50 ms 的帧时，当前 episode 拒绝。
|
||||
|
||||
不采用官方旧加载器中的 `action[t-1]` 补丁。HDF5 根属性写入：
|
||||
|
||||
```text
|
||||
action_alignment = "same_step_causal"
|
||||
```
|
||||
|
||||
控制、反馈、动作和图像源时间戳全部保存在 `/debug`，未来只有在真实延迟测量证明
|
||||
存在稳定偏移时，才在训练加载器中调整；原始 HDF5 不进行不可逆移位。
|
||||
|
||||
## Episode 边界与手柄状态机
|
||||
|
||||
### 按键映射
|
||||
|
||||
- 右手 B，即右手 `secondary` 单击：开始准备或结束保存；
|
||||
- 左手 Y，即左手 `secondary` 长按 1 秒：丢弃当前准备/录制；
|
||||
- 右手 A，即右手 `primary`：继续保持现有右臂回初始位姿功能；
|
||||
- Grip：继续只控制遥操离合，不作为“只在按下时才记录”的采集开关。
|
||||
|
||||
右手 B 在右手 Grip 按下时始终忽略，避免运动中误触开始或结束。左手 Y 仅在
|
||||
`ARMED` 或 `RECORDING` 中长按有效，在 `IDLE` 中无作用，且永远不删除上一个已经
|
||||
保存的 episode。
|
||||
|
||||
### 状态机
|
||||
|
||||
```text
|
||||
IDLE
|
||||
└─ Grip 松开时单击右手 B
|
||||
├─ 预检失败 → IDLE
|
||||
└─ 预检通过 → ARMED
|
||||
|
||||
ARMED
|
||||
├─ 第一次 Grip 有效动作 → RECORDING
|
||||
├─ 再次单击右手 B → 取消 → IDLE
|
||||
├─ 长按左手 Y 1 秒 → DISCARDED → IDLE
|
||||
└─ 按右手 A → 取消 → IDLE
|
||||
|
||||
RECORDING
|
||||
├─ Grip 松开后单击右手 B → SAVING
|
||||
├─ 长按左手 Y 1 秒 → DISCARDED → IDLE
|
||||
├─ 按右手 A → REJECTED → IDLE
|
||||
└─ 硬质量故障/60 秒上限/Ctrl+C → REJECTED → IDLE
|
||||
|
||||
SAVING
|
||||
├─ 质量检查通过 → SAVED → IDLE
|
||||
└─ 质量检查失败 → REJECTED → IDLE
|
||||
```
|
||||
|
||||
`IDLE`、`ARMED`、`RECORDING`、`SAVING` 是运行状态；`SAVED`、`DISCARDED`、
|
||||
`REJECTED` 是短暂结果状态，发布一次结果并输出日志后回到 `IDLE`。`SAVING`
|
||||
期间忽略 B/Y 录制按键，A 键仍属于原有遥操逻辑，但不会再进入已经结束的数据。
|
||||
|
||||
状态通过 `std_msgs/msg/String` 话题 `/act/recording_status` 和终端日志报告，不增加
|
||||
新状态消息、声音或震动接口。
|
||||
|
||||
### 连续记录与 Grip 暂停
|
||||
|
||||
正式时间轴从 `ARMED` 后 Grip 按下且第一次
|
||||
`action_valid=true、command_sent=true` 的控制周期开始。Grip 刚按下的建基准周期
|
||||
尚未向 RM75 发送新的 CANFD 目标，因此不作为第一个训练样本。
|
||||
录制过程中临时松开 Grip 时仍以 30 Hz 保存图像和 `qpos`，`action` 零阶保持上次
|
||||
成功目标，并记录 `teleop_active=false`：
|
||||
|
||||
- 松开后重新按 Grip：暂停区间保留，继续同一个 episode；
|
||||
- 最后一次松开后按 B：将该次松开至 B 之间的纯操作等待数据裁掉，episode 结束在
|
||||
最后一次 Grip 松开附近；
|
||||
- 夹爪打开确认必须已经包含在裁剪终点之前，否则拒绝该 episode。
|
||||
|
||||
只在 Grip 按下时保存数据会丢失接近任务开始、暂停恢复和完整视觉上下文，因此不
|
||||
采用该方案。
|
||||
|
||||
### Episode 是否包含 A 键回位
|
||||
|
||||
一个正式 episode 只包含：
|
||||
|
||||
```text
|
||||
初始位姿、夹爪打开
|
||||
→ 接近番茄
|
||||
→ 闭合夹爪
|
||||
→ 搬运至收集篮
|
||||
→ 打开夹爪并确认成功
|
||||
→ 松开 Grip
|
||||
→ 按 B 结束
|
||||
```
|
||||
|
||||
A 键的 `rm_movej(initial_joint_pose)` 必须在成功结束 episode 后执行，不写进
|
||||
episode。这样 ACT 始终学习同一种逐周期 `q_target` 动作语义。未来实时推理若要
|
||||
连续采摘，应由上层状态机执行：
|
||||
|
||||
```text
|
||||
ACT 完成一次采摘 → 完成判定 → 固定 rm_movej 复位 → 下一次 ACT 采摘
|
||||
```
|
||||
|
||||
若在 `RECORDING` 中误按 A，当前文件转入拒绝目录，原因写为：
|
||||
|
||||
```text
|
||||
initial_pose_command_during_episode
|
||||
```
|
||||
|
||||
拒绝数据不会拦截 A 键原有回位动作，也不会额外控制机器人。
|
||||
|
||||
## HDF5 核心结构
|
||||
|
||||
数据根目录和任务目录固定为：
|
||||
|
||||
```text
|
||||
/home/robot/ACT_Data
|
||||
/home/robot/ACT_Data/tomato_pick
|
||||
```
|
||||
|
||||
正式文件核心结构：
|
||||
|
||||
```text
|
||||
/observations/qpos float32 (T, 8)
|
||||
/observations/images/cam_high uint8 (T, 480, 640, 3)
|
||||
/observations/images/cam_right_wrist uint8 (T, 480, 640, 3)
|
||||
/action float32 (T, 8)
|
||||
/debug/...
|
||||
```
|
||||
|
||||
`T` 是该次任务的实际样本数，不要求所有 episode 等长，不进行文件内 padding。
|
||||
最短有效 episode 为 `60` 个样本，即 2 秒；最长为 `1800` 个样本，即 60 秒。
|
||||
|
||||
8 维字段顺序固定为：
|
||||
|
||||
```text
|
||||
qpos[0:7] = RM75 实际反馈关节角，单位 rad
|
||||
qpos[7] = 已确认夹爪逻辑状态，0 closed、1 open
|
||||
|
||||
action[0:7] = 最终成功下发或明确定义为保持的关节目标，单位 rad
|
||||
action[7] = 夹爪请求目标，0 closed、1 open
|
||||
```
|
||||
|
||||
根属性至少包括：
|
||||
|
||||
| 属性 | 值或语义 |
|
||||
|---|---|
|
||||
| `sim` | `false`，与 ALOHA 真实数据约定一致 |
|
||||
| `task_name` | `tomato_pick` |
|
||||
| `sample_rate_hz` | `30` |
|
||||
| `action_alignment` | `same_step_causal` |
|
||||
| `arm` | `right_rm75` |
|
||||
| `episode_status` | `saved` 或 `rejected` |
|
||||
| `camera_high_serial` | `234222303366` |
|
||||
| `camera_right_wrist_serial` | `412622272532` |
|
||||
| `joint_names` | 7 个 RM75 关节名和 `gripper` 的固定顺序 |
|
||||
| `joint_lower_limits` | 来自当前 Placo/URDF 的 7 关节下限 |
|
||||
| `joint_upper_limits` | 来自当前 Placo/URDF 的 7 关节上限 |
|
||||
| `reject_reason` | 仅拒绝文件存在 |
|
||||
| `interrupted` | 正常文件为 `false`，Ctrl+C/异常恢复为 `true` |
|
||||
|
||||
图像不压缩，每帧使用一个 HDF5 chunk；数值数据使用可扩展的一维时间轴并分块
|
||||
写入。按两路 `640×480×3×30` 计算，图像数据约为 3.3 GB/分钟，因此不能把完整
|
||||
episode 先缓存到内存再一次性保存。
|
||||
|
||||
不创建 `/observations/qvel`、`/observations/effort`、压缩标记或 `compress_len`；
|
||||
也不使用零值、有限差分或其他伪数据填充缺失字段。后续训练加载器按存在的核心
|
||||
字段读取。
|
||||
|
||||
## Debug 结构
|
||||
|
||||
自定义消息是运行时传输载体，进程退出后不会保留；HDF5 `/debug` 是永久诊断记录。
|
||||
ACT 训练默认不读取该组。
|
||||
|
||||
建议使用以下精简结构，布尔状态以 `uint8` 保存：
|
||||
|
||||
```text
|
||||
/debug/timestamps/control_monotonic_ns int64 (T,)
|

/debug/gripper/command_pending uint8 (T,)
|
||||
/debug/gripper/command_failed uint8 (T,)
|
||||
```
|
||||
|
||||
位姿顺序统一为 `[x, y, z, qx, qy, qz, qw]`，TCP 速度顺序统一为
|
||||
`[vx, vy, vz, wx, wy, wz]`。`right_inputs` 顺序在文件属性中写明。当前周期没有发送
|
||||
动作时，`action_monotonic_ns=-1`，并以 `command_sent=false` 消除歧义。
|
||||
|
||||
episode 根属性额外保存 QP 失败次数、失败占比、最长连续失败次数、目标限位次数、
|
||||
相机帧率、丢帧率和最大时间偏差等汇总指标。
|
||||
|
||||
## 数据质量规则
|
||||
|
||||
### 开始前预检
|
||||
|
||||
Grip 松开时单击 B 后，采集节点检查：
|
||||
|
||||
- 输出目录存在或可以创建且可写；
|
||||
- 可用空间不少于 4 GiB，约为 60 秒原始图像估算值的 1.2 倍；
|
||||
- 两台指定相机均在线、已经连续预热 5 秒且当前帧率合格；
|
||||
- 最近 `q_actual` 合法，反馈年龄不超过 50 ms，RM75 无掉使能或控制故障；
|
||||
- 右臂夹爪初始化打开命令已经成功；
|
||||
- 左右 PICO 话题均在现有手柄超时范围内保持新鲜；
|
||||
- 没有第二个采集进程持有任务目录锁或相机设备；
|
||||
- 启动组合是 `arm:=right use_mock:=false record_act:=true`。
|
||||
|
||||
任一预检失败时输出明确原因并停留在 `IDLE`，不生成空文件，也不改变机器人状态。
|
||||
|
||||
### 硬拒绝条件
|
||||
|
||||
以下任一情况使当前 episode 进入 `REJECTED`：
|
||||
|
||||
- 样本少于 60 或达到 60 秒上限；
|
||||
- 控制周期序列缺失、有效平均采样率低于 27 Hz 或相邻样本间隔超过 100 ms；
|
||||
- `qpos/action` 不是 `(T,8)`、包含 NaN/Inf、违反配置关节限制或夹爪值不是
|
||||
`0/1`；
|
||||
- `q_actual` 年龄超过 50 ms，反馈超时、掉使能或出现控制故障；
|
||||
- 最终关节动作发送失败，或消息表示的反馈和动作不属于同一控制周期；
|
||||
- 夹爪命令失败、超时，或最终裁剪数据没有包含已确认的打开状态；
|
||||
- 任一路相机平均帧率低于 27 FPS；
|
||||
- 任一路相机硬件帧号丢失率超过 1%，或采样后的重复/跳帧比例超过 1%；
|
||||
- 任一采样图像年龄超过 50 ms，或两路图像主机时间差超过 50 ms；
|
||||
- 图像形状、数据类型或 RGB 通道约定错误；
|
||||
- 录制中按 A；
|
||||
- HDF5 写入失败、磁盘空间不足或有界写入队列持续积压；
|
||||
- Ctrl+C、采集节点异常退出或启动时恢复崩溃残留文件。
|
||||
|
||||
采集节点的拒绝只处理数据，不额外发送停止或运动命令。若原因来自控制故障，仍由
|
||||
现有遥操安全链路执行原有安全停止。
|
||||
|
||||
### 允许但记录告警的情况
|
||||
|
||||
QP 求解偶发失败时，现有逻辑保留上次有效关节目标。只要该保持目标最终成功发送、
|
||||
反馈和其他质量规则正常，就不自动拒绝 episode，而是保存：
|
||||
|
||||
- QP 失败样本数；
|
||||
- 失败占比；
|
||||
- 最长连续失败样本数；
|
||||
- 每个样本的 `qp_success`。
|
||||
|
||||
工作空间限位、TCP 步长限制或关节速度/加速度限制生效同样只记录，不自动拒绝。
|
||||
这些限制是正常安全控制的一部分。
|
||||
|
||||
## 文件编号、保存、拒绝与恢复
|
||||
|
||||
正式编号只扫描任务目录根部的 `episode_<数字>.hdf5`，取最大编号加一：
|
||||
|
||||
```text
|
||||
已有 episode_0.hdf5 ... episode_9.hdf5
|
||||
重启后下一个正式文件仍为 episode_10.hdf5
|
||||
```
|
||||
|
||||
不填补编号空洞，绝不覆盖已有正式文件。任务目录使用标准库文件锁保证同一时刻只有
|
||||
一个采集进程分配编号和写入；临时文件与目标文件位于同一文件系统，检查通过后使用
|
||||
不覆盖已有目标的原子发布方式。
|
||||
|
||||
文件生命周期：
|
||||
|
||||
```text
|
||||
录制中：
|
||||
/home/robot/ACT_Data/tomato_pick/episode_10.partial.hdf5
|
||||
|
||||
检查通过：
|
||||
/home/robot/ACT_Data/tomato_pick/episode_10.hdf5
|
||||
|
||||
检查失败：
|
||||
/home/robot/ACT_Data/tomato_pick/rejected/
|
||||
episode_10_<reason>_<timestamp>.hdf5
|
||||
```
|
||||
|
||||
- 只有正式保存成功才消耗编号；
|
||||
- 手动长按 Y 丢弃时关闭并删除当前临时文件，不生成拒绝文件；
|
||||
- 普通质量拒绝转入 `rejected/`，不消耗正式编号；
|
||||
- Ctrl+C 时尽力关闭可读 HDF5，根属性写入 `interrupted=true`，文件名原因使用
|
||||
`interrupted`；
|
||||
- 下次启动先处理遗留临时文件：可读文件转入 `rejected/` 并标记
|
||||
`crash_recovered`，不可读文件改成带时间戳的 `.partial.hdf5` 保留；
|
||||
- 拒绝原因同时写入文件名和根属性；
|
||||
- 任一步出现目标文件冲突时停止保存并报警，不能覆盖或自动删除已有 episode。
|
||||
|
||||
写入采用单独工作线程和有界队列，ROS 回调只完成取样、对齐和入队。队列容量只需
|
||||
覆盖短暂磁盘抖动，不能无限增长掩盖磁盘吞吐不足；持续积压时拒绝数据。
|
||||
|
||||
## 启动、配置与依赖
|
||||
|
||||
继续使用唯一入口 `xr_rm_bringup/launch/arm_debug.launch.py`，新增参数：
|
||||
|
||||
```text
|
||||
record_act:=false
|
||||
```
|
||||
|
||||
默认 `false`，现有 mock、单臂、双臂和 MuJoCo 启动行为不变。第一阶段唯一允许的
|
||||
采集组合为：
|
||||
|
||||
```bash
|
||||
ros2 launch xr_rm_bringup arm_debug.launch.py \
|
||||
arm:=right use_mock:=false record_act:=true
|
||||
```
|
||||
|
||||
`record_act:=true` 配合 `arm:=left|both` 或 `use_mock:=true` 时，在 launch 参数校验
|
||||
阶段明确拒绝。ACT 采集节点退出不触发整个 launch 的 `Shutdown`，保证数据进程故障
|
||||
不会终止遥操；终端必须清晰显示采集已经不可用。
|
||||
|
||||
新增一份专用 YAML，集中保存：
|
||||
|
||||
- 数据根目录和任务名；
|
||||
- 两个相机序列号、分辨率和帧率；
|
||||
- 30 Hz 采样率、2 秒最短时长和 60 秒最长时长；
|
||||
- 相机、反馈、磁盘和时间对齐质量阈值；
|
||||
- PICO 左右话题、原子采样话题和状态话题。
|
||||
|
||||
硬件相关阈值保留为配置项，核心 HDF5 字段顺序和 8 维语义固定，不为未来可能的
|
||||
变体增加插件或通用框架。
|
||||
|
||||
采集节点继续由 `/home/robot/miniconda3/envs/xr/bin/python` 启动。复用该环境已有的
|
||||
`pyrealsense2` 和 NumPy，只在该环境增加 HDF5 必需依赖 `h5py`；不修改系统 Python，
|
||||
不新增 Conda 环境，也不增加 OpenCV 依赖。依赖缺失时节点应在打开相机或创建文件前
|
||||
给出明确错误。
|
||||
|
||||
## 最小代码范围
|
||||
|
||||
预计只修改或新增以下位置：
|
||||
|
||||
- `xr_rm_interfaces/msg/ActControlSample.msg`：原子消息；
|
||||
- `xr_rm_interfaces/CMakeLists.txt`、`package.xml`：生成并导出消息；
|
||||
- `xr_rm_teleop/xr_rm_teleop/single_arm_velocity_teleop.py`：发布原子样本、跟踪夹爪
|
||||
请求/成功状态和 A 键事件；
|
||||
- `xr_rm_teleop/xr_rm_teleop/fun_peripheral.py`：把请求的初始工具状态明确改为完全
|
||||
打开；
|
||||
- `xr_rm_teleop/xr_rm_teleop/act_episode_recorder.py`：独立采集节点；
|
||||
- `xr_rm_teleop/setup.py`、`package.xml`：安装入口和 ROS 运行依赖声明；
|
||||
- `xr_rm_bringup/config/act_tomato_pick.yaml`：采集与硬件参数；
|
||||
- `xr_rm_bringup/config/peripherals_rm75.yaml`：只为右臂启用初始化打开；
|
||||
- `xr_rm_bringup/launch/arm_debug.launch.py`：默认关闭的 `record_act` 启动分支；
|
||||
- 现有测试目录中的最小相关测试。
|
||||
|
||||
不改左臂/双臂运动参数，不改变 `left_arm_teleop`、`right_arm_teleop` 节点名，不创建
|
||||
第二个相机包、训练包或数据工具包。
|
||||
|
||||
## 测试与验收
|
||||
|
||||
### 自动化验证
|
||||
|
||||
测试全部使用 mock、假适配器、合成相机帧和临时目录，不连接真机、不移动机械臂、
|
||||
不操作真实夹爪：
|
||||
|
||||
- 原子消息中的 `q_actual`、QP 输出和最终 `q_target` 来自同一控制周期；
|
||||
- QP 失败时记录失败并保持上次目标，不自动拒绝；
|
||||
- 发送失败、夹爪失败和 A 键误触触发拒绝；
|
||||
- Trigger 请求立即改变 `action[7]`，成功返回后才改变 `qpos[7]`；
|
||||
- B/Y/Grip 的边沿、长按、忽略条件和所有状态转换正确；
|
||||
- 从首次有效样本开始按控制序号每 3 个周期取 1 个；
|
||||
- 相机只选择不晚于控制时间的最新帧，并能发现过期、偏斜和帧号异常；
|
||||
- Grip 中途暂停保留，最终松开到 B 的等待段正确裁剪；
|
||||
- HDF5 核心路径、形状、dtype、8 维顺序、根属性和 debug 字段正确；
|
||||
- 变量长度、最短/最长限制、质量拒绝、手动丢弃和 Ctrl+C 正确；
|
||||
- 编号从最大正式编号加一，拒绝不占号，已有文件不被覆盖；
|
||||
- 可读和不可读崩溃残留分别按设计恢复；
|
||||
- `record_act` 默认关闭，非法 arm/mock 组合被 launch 拒绝；
|
||||
- mock 模式不会导入或调用 RealMan SDK、RealSense 或 HDF5 采集链路。
|
||||
|
||||
按照仓库要求，构建和测试从工作空间根目录执行：
|
||||
|
||||
```bash
|
||||
cd /home/robot/WS_xr
|
||||
source /opt/ros/humble/setup.bash
|
||||
colcon build --symlink-install
|
||||
pytest src/xr_rm_teleop/test/test_orientation_control.py
|
||||
```
|
||||
|
||||
实施时还应运行新增测试及受影响的现有关节控制、初始位姿和外设配置测试。未看到
|
||||
实际通过输出前不得声称验证通过。
|
||||
|
||||
### 真机手工验收
|
||||
|
||||
真机验收必须由用户明确授权并在现有安全检查完成后进行，至少验证：
|
||||
|
||||
1. 启动后右臂夹爪完全打开，状态未在命令成功前提前标记；
|
||||
2. 两台相机序列号和画面角色正确，持续 30 FPS 左右；
|
||||
3. B 开始、Grip 激活、B 结束、Y 丢弃和 A 误触拒绝符合状态机；
|
||||
4. 正常采摘文件包含完整抓取、搬运和释放，不包含 A 键回位；
|
||||
5. `qpos/action` 是有限的 `(T,8)` `float32`，图像是两路
|
||||
`(T,480,640,3)` `uint8`；
|
||||
6. QP 短暂失败只增加 debug 计数，成功调整后仍可完成 episode；
|
||||
7. 重启后编号继续递增，丢弃和拒绝不会覆盖或占用正式编号；
|
||||
8. Ctrl+C、相机断流和磁盘不足产生带明确原因的拒绝文件；
|
||||
9. ACT 采集节点退出后，遥操安全链路仍按现有行为运行。
|
||||
|
||||
## 后续训练与推理影响
|
||||
|
||||
本设计生成 ALOHA/ACT 风格的核心数据，但原始 ACT 代码通常把状态维度硬编码为
|
||||
双臂 14 维，并可能假设固定 episode 长度。训练阶段需要单独适配：
|
||||
|
||||
- `state_dim=8`；
|
||||
- 两个相机名 `cam_high`、`cam_right_wrist`；
|
||||
- 变量长度 episode 的 padding 和 mask；
|
||||
- `chunk_size≈60`；
|
||||
- 不使用 `action[t-1]` 旧补丁；
|
||||
- 忽略 `/debug`，除非用于筛选或诊断。
|
||||
|
||||
实时推理只负责从初始位姿执行一次采摘到释放。回初始位姿继续调用当前确定性的
|
||||
`rm_movej`，由未来的上层任务状态机协调，避免让一个低层策略混合两种动作接口和
|
||||
任务阶段。
