 `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`。
 
+`xr_rm_bringup/config/peripherals_rm75.yaml` 保存末端工具坐标、负载和左右臂外设选择。当前配置为左臂 `scissorgripper=1`、右臂 `scissorgripper=2`，并且只在真机连接阶段初始化外设，不在主遥操作循环里控制开合。
+
+## 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。启动后可以用 Bool 话题控制开合，`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}"

+
+桌面 UI 的 `Left Arm`、`Right Arm` 和 `Dual Arm` 模式里也有对应的 Tool Open/Close 命令项。

 - `controller_topic`：订阅的手柄话题。
