4. Guide de configuration
4.1 Installation de l'alimentation électrique
The UGV02 requires three 18650 Li-ion batteries (not included) for operation. These batteries are installed in the 3S UPS power supply module.
- Ensure the UGV02 is powered off.
- Repérez le compartiment de la batterie sur le châssis.
- Insert three 18650 Li-ion batteries into the 3S UPS power supply module, ensuring correct polarity.
- Fixez le couvercle du compartiment à piles.
- Connect the power supply module to the UGV02's charging port.

4.2 Host Computer Connection (Optional)
The UGV02 supports various host computers like Raspberry Pi, Jetson Nano, or Jetson Orin Nano. The host computer communicates with the onboard ESP32 slave computer via a serial port.
- Choose your desired host computer.
- Mount the host computer onto the UGV02 chassis using the provided mounting plate or extension rails.
- Connect the host computer to the ESP32 slave computer via the serial communication interface. Refer to the host computer's documentation for specific serial port configuration.
- If using Wi-Fi, connect the Wi-Fi antenna to the reserved interface on the UGV02.

5. Mode d'emploi
5.1 Mise sous/hors tension
Locate the Power ON/OFF switch on the UGV02 chassis. Press the switch to power on or power off the robot.
5.2 Basic Control via Web Application
The UGV02 features an open-source web application for remote control and monitoring.
- Power on the UGV02. If it is not connected to a known Wi-Fi network, it will automatically establish a hotspot.
- Connect your smartphone or computer to the UGV02's Wi-Fi hotspot.
- Ouvrir un web browser and navigate to the IP address provided by the UGV02 (usually displayed on the 0.91-inch OLED screen or found in the hotspot details).
- Le web application interface will allow you to control the robot's movement, monitor voltage, heading angle, and other parameters.
