Development of IoT Based and Wi-Fi Controlled Communication Robot by using Node MCU

Abstract

This paper explains the Internet of Things (IoT) based Wi-fi controlled robot by using Node MCU for android applications. Some of the sensors such as temperature sensor, pressure sensor, humidity sensor, ultrasonic sensor is used to develop the smart application. The smart robot has been implemented and used with android mobile instead of a normal joystick method. The reaction time of the sensors is less than 0.03sec. The humidity sensor can be able to range upto10 to 45 degrees. The main aim of this application is to control the robot by an android application and can be controlled with a distance up-to 200mts. The rate of data will be refreshed in the database in every 30 seconds, which means the developed smart robot can work dynamically. These types of Robots are called Nonautonomous robots. This application has been developed by using Node MCU.
