Robotic Car Using NodeMCU ESP8266 Wi-Fi Module

This paper presents an insight into a Wi-Fi controlled car using NodeMCU ESP8266 module for car controlling, and ESP32 Cam Module, which collects the visual data, as well as maintains the Wi-Fi connection. This robot can be remotely controlled even if it’s out of sight, but within the optimum range of the connection technology, Wi-Fi. The physical movement of this robot, is controlled using the L298N Motor Driver, which in turn is connected to the 4 DC motors, and the control from this motor driver, would be directed through these 4 motors to the respective wheels, thereby letting the user to control the movement of the robot. Along with this, the ESP32 Cam Module would collect the visual data of the nearby close areas, and relay it back to the Wi-Fi connected device, which could be a smartphone or any such device. The base hardware on which this robot unit is made, is hard plastic which gives the unit a physical durability, and thus usable for use in rough areas like industrial sites or in underground mines for surveillance purposes.
