CONSTRUCTION OF A GESTURE- CONTROLLED ROBOTIC CAR USING NODEMCU

Abstract

Robots are now an essential part in the modern society. Nowadays robots are everywhere, their application are far reaching and can encompass a variety of different machines with different purposes. The major goal of the project work is to control the movement of a robot through gestures. The system is made up of two major components: An android device with an app capable of reading the gyroscope sensor embedded in the device, which is controlled by tilting the device. The tilting of the device sends data signals through a Wi-Fi network. This signal is processed with the assistance of the NodeMCU, which instructs the robot to move in the specified direction by sending voltages to the motor driver. The essential operation of the robot is the transmission of data signals from an android device, readings, to the NodeMCU board installed on the robot. The software compiled in the NodeMCU executes according to that value, causing the robot to work properly while connected to the hotspot of the android device. The gyroscope sensor operates on two axis. One axis controls the forward or reverse speed, while the other controls the turning mechanism. Wi-Fi controlled robots can be very useful in rescuing individuals from collapsed buildings due to natural disasters, and can also be implemented in almost any sector in the world.
