+- 🚀 Step 1: Install the Orbbec SDK Dependent Environment
+
+1. Clone the `pyorbbec` repository
+   ```bash
+   cd ~/
+   git clone https://github.com/orbbec/pyorbbecsdk.git
+   ```
+
+2. Download and install the corresponding **.whl file** for the SDK  
+   Go to [pyorbbecsdk Releases](https://github.com/orbbec/pyorbbecsdk/releases),  
+   select and install based on your Python version. For example:
+   ```bash
+   pip install pyorbbecsdk-x.x.x-cp310-cp310-linux_x86_64.whl
+   ```
+
+3. Install dependencies in the `pyorbbec` directory
+   ```bash
+   cd ~/pyorbbecsdk
+   pip install -r requirements.txt
+   ```
+
+   Force downgrade the `numpy` version to `1.26.0`
+    ```bash
+    pip install numpy==1.26.0
+    ```
+  Red error messages can be ignored.
+
+4. Clone the Orbbec SDK into the `~/lerobot/src/cameras` directory
+
+  ```bash
+  cd ~/lerobot/src/cameras
+  git clone https://github.com/ZhuYaoHui1998/orbbec.git
+  ```
+
+5. Modify utils.py and __init__.py

+
+```python

+            from .realsense.camera_orbbec import OrbbecCamera

+</div>
+
+
+- 🚀 Step 2: Function Call and Examples
+
+In all the following examples, replace `so101_follower` with the actual model of the robotic arm you are using (e.g., `so100` / `so101`).
+
+
+We have added the `focus_area` hyperparameter. Since depth data that is too far away is meaningless for the robotic arm (it cannot reach or grasp objects), depth data less than or greater than the `focus_area` will be displayed in black. The default `focus_area` is (20, 600).  
+Currently, the only supported resolution is width: 640, height: 880.
+
+```bash
+lerobot-teleoperate \
+    --robot.type=so101_follower \
+    --robot.port=/dev/ttyACM0 \
+    --robot.id=my_awesome_follower_arm \
+    --robot.cameras="{ up: {type: orbbec, width: 640, height: 880, fps: 30, focus_area:[60,300]}}" \
+    --teleop.type=so101_leader \

+    <img width={800}
+    src="https://files.seeedstudio.com/wiki/robotics/projects/lerobot/starai/orbbec_result.png" />
+</div>
+
+
+
+For subsequent tasks such as data collection, training, and evaluation, the process is the same as that for regular RGB commands. You only need to replace the relevant part in the regular RGB command with:
+
+```bash
+  --robot.cameras="{ up: {type: orbbec, width: 640, height: 880, fps: 30, focus_area:[60,300]}}" \
+```
+
+You can also add an additional monocular RGB camera afterward.

 After inserting your two USB cameras, run the following script to check the port numbers of the cameras.

The slower speed of a USB Hub may result in the inability to read image data.
