 ### 3. Manual Drag Data Collection
 
-Manual drag recording uses `manual_mode: true` in the robot configuration and does not configure a teleoperator. During recording, the actual joint state is written as both the observation and action in the LeRobot dataset:
+Manual drag recording uses `manual_mode: true` in the robot configuration and does not configure a teleoperator. During recording, the actual joint state is written as both the observation and action in the LeRobot dataset. When a gripper is configured, hold `C` to close it slowly and `O` to open it slowly. Adjust the speed with `manual_gripper_speed`, which defaults to `0.5`:

+人工拖拽录制使用 robot 配置中的 `manual_mode: true`，不需要配置 teleop。录制过程中，机械臂的实际关节状态会作为 observation 和 action 写入 LeRobot 数据集；如果配置了夹爪，还可以按住 `C` 缓慢闭合、按住 `O` 缓慢张开。夹爪速度通过 `manual_gripper_speed` 配置，默认值为 `0.5`：
