2. For Arduino module:
   Install arduinoSTL by [Manage Libraries...]
   

Download and extract in [your arduino ide folder]/tools. https://github.com/me-no-dev/arduino-esp32fs-plugin/releases/

1. ESP32-CAM module firmware(ESP32CamRobot): contains 2 parts
   

• data: contains the GUI (html, icon), use SPIFFS upload tool to upload to the module
  
• ESP32CamRobot sketch: normally upload by arduino IDE
  

2. Arduino Uno firmware (ESP32CamRobotMotors): normally upload by arduino IDE
   

Use Arduino IDE serial monitor tool to capture the serial data from ESP32-CAM module on starting up to get the camera IP address.
Use your webbrowser to connect to the that IP.
