The ESP32-CAM module streams images to an app, hosted by an Android tablet or mobile phone, with Wi-Fi communication over a WLAN or a software-enabled access point, softAP, provided by the ESP32 microcontroller (see Figure 14-1). The robot car is powered by two DC motors with the ESP32-CAM module mounted on a servo motor tilt bracket to provide different observation positions. The app transmits HTTP GET requests, to the ESP32-CAM microcontroller, containing the image resolution, direction or heading angle, and motor speed for the robot car and the servo motor inclination angle. The ESP32-CAM module updates the camera image resolution and responds to the HTTP GET request by providing the image resolution details. The heading angle is converted to the rotation directions and speeds for the two DC motors to update the direction of travel of the robot car. The response to the HTTP GET request also includes direction of travel and motor speed information and the Wi-Fi signal strength for display on the app.
