## 2. How to Use Teach & Play
**(1) Adding a Movement**
* Click the **\[Add]** button to open the movement recording screen.
(2) Disabling Motors & Recording Movement
* Click the **\[Turn Motors Off]** button to disable all motors of the HUENIT robotic arm.
* The **\[Turn Motors Off]** button will then change to **\[Add Movement]**.
* With the motors disabled, manually move the robotic arm to the desired position and click **\[Add Movement]**.
* The motors will be re-enabled, and the current **(x, y, z)** coordinates of the robotic arm will be saved.
* Click the **\[Back]** button on the AI Camera to confirm that the new coordinate has been added.
* If a **\[****]** mark appears next to the saved coordinate, the robotic arm can move to that position.
* If a **\[****]** mark appears next to a new coordinate, the movement to that position is not possible.
(3) Adding a Delay Between Movements
* To set a waiting time between movements, select **\[wait 1 sec]** using the **\[Up/Down]** buttons.
* Then, click **\[Add Module]** as many times as needed to set the desired waiting time.
(4) Executing the Saved Movements
* After adding all the desired movements, click **\[PLAY]** to execute the stored movements sequentially.
(5) Deleting Unnecessary Movements
* To delete a movement, select the unwanted item using the **\[Up/Down]** buttons and click **\[DEL (Delete)]**.
(6) Adding Suction & Gripper Module Movements
* In addition to robotic arm movements, the **Suction Module** and **Soft Gripper Module** actions can be added.
* Click **\[Add]**, select the module movement using the **\[Up/Down]** buttons, and click **\[Add Module]**.
* **Note:** If module actions are added, the corresponding module must be attached before clicking **\[PLAY]** to ensure proper execution.
## 3. **Saving Teach & Play Data**
* The recorded robotic arm movements in **Teach & Play** can be saved to the HUENIT OS memory.
* Click **\[Save]**, select the desired storage location, and the movements will be saved.
## 4. Auto-Save Function
* If the connection between the robotic arm and AI Camera is lost while using **Teach & Play**, the progress will be **automatically saved**.
* When the AI Camera is reconnected to the robotic arm, the system will prompt the user **only once** to reload the **auto-saved data**.
