Setup

1. Software Installation

To program the ESP32 CAM module, you will need the Arduino IDE. Download and install it from the official Arduino website: https://www.arduino.cc/en/software.

Install the ESP32 board package in the Arduino IDE. Go to File > Preferences, and add the following URL to "Additional Board Manager URLs": https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json.

Then, go to Tools > Board > Board Manager, search for "esp32", and install the "esp32 by Espressif Systems" package.

Select the correct ESP32 CAM board (e.g., AI Thinker ESP32-CAM) from Tools > Board.

2. Connecting the ESP32

Connect the ESP32 CAM module to your computer using the provided USB cable. Ensure the correct COM port is selected in Tools > Port in the Arduino IDE.

Upload the example code (typically found in the kit's tutorial or online resources) to the ESP32 CAM module. This code will enable the camera and WiFi functionality.

Operating Instructions

1. Powering On

Insert two 18650 batteries (not included) into the battery case. Ensure correct polarity.

Switch on the power supply module. The robot car will power up, and the ESP32 CAM module will begin its initialization process.

2. Connecting to the Robot Car

The ESP32 CAM module creates its own WiFi access point. On your smartphone or computer, connect to the WiFi network named by the ESP32 (e.g., "ESP32-CAM-AP").

Open a web browser and navigate to the IP address provided by the ESP32 (usually 192.168.4.1). This will open the control interface.

A smartphone screen displaying the web-based control interface for the robot car, with buttons for 'Stop', 'Forward', 'Left', 'Right', 'Reverse', 'Light On', 'Light Off', and a speed slider. A live camera feed is visible at the top.

3. Controlling the Robot Car

Use the on-screen buttons to control the robot's movement: Forward, Reverse, Left, Right, and Stop.

Adjust the speed using the provided slider or input field.

The camera provides a live video feed to your device, allowing for remote observation.

The camera can also detect obstacles, depending on the uploaded program.

Maintenance

• Keep the robot car clean and free from dust and debris.
• Regularly check all screw connections and tighten if necessary.
• Ensure battery contacts are clean and free of corrosion.
• Store the robot car in a dry, cool place when not in use.
• Avoid exposing electronic components to moisture or extreme temperatures.

Troubleshooting

Robot not moving:

• Check battery charge and polarity.
• Verify all motor and power connections are secure.
• Ensure the motor driver (L298N) is correctly wired and receiving power.
• Confirm the program is uploaded correctly to the ESP32.

No camera feed or WiFi connection:

• Ensure the ESP32 CAM module is powered on.
• Check the WiFi antenna connection.
• Verify the ESP32 program for WiFi and camera functionality is uploaded and running.
• Confirm your device is connected to the ESP32's WiFi network.
• Try restarting the robot car and your controlling device.

Loose components:

• Tighten any loose screws. Some users have reported issues with component mounting; consider adding additional fasteners if parts feel unstable.
