+# Depth work mode switch
+
+Orbbec SDK ROS 2 supports the depth work mode switch. The depth work mode switch is supported by Gemini 2, Gemini 2 L,
+and Femto and Femto Bolt cameras.
+
+- Before starting the camera, depth work mode (depth_work_mode) can be configured for the corresponding xxx.launch.py
+  file's support.
+- The depth work mode switch is supported by Gemini 2, Gemini 2 L, and Gemini 2 XL cameras.
+- The default depth work mode configuration of xxx.launch.py is the camera's default configuration. If you need to
+  modify it, you can switch to the corresponding mode as needed.
+- The specific camera depth work mode support types can be found in the comments of the depth mode.
+
+```python
+# Depth work mode support is as follows:
+# Unbinned Dense Default
+# Unbinned Sparse Default
+# Binned Sparse Default
+# Obstacle Avoidance
+DeclareLaunchArgument('depth_work_mode', default_value='')
+```
+
+- View depth work modes:
+
+```bash
+ros2 run orbbec_camera list_depth_work_mode_node
+```
+
+* Example:
+
+```bash
+ros2 launch orbbec_camera gemini2L.launch.py depth_work_mode:="Unbinned Dense Default"
+```
