ABSTRACT Robots have suddenly started grabbing attention in this world for their applications. Wi-Fi controlled robots or NodeMCU helps to rescue individuals from collapsed buildings due to natural disasters. Currently the operations of Robots are controlled by remote sensor technology. The proposed concept of this modified Wi-Fi controlled robots or node MCU Robot used for navigation or location identification. By Introducing this navigation and location identification concepts in robots can save human beings from a risky and harmful natural disasters especially that happens in power plants.

INTRODUCTION NODEMCU The evolution of wireless communication NodeMCU is a microcontroller though it is plays a vital role in the industry 4.0 already integrated with esp12. It is most campaign. Wireless systems are employed preferable for IoT start-up students. It is in different dimensions like security, applicable for the devices using wi-fi as manpower, machine learning[1], database well as tethering hotspot. Here, we are management systems and so on. Here, doing this prototype using Arduino IDE. In wireless controlled RCC car[2] is a result such a prototype the NodeMCU connects of networking patriarchy. Wi-Fi with the router, which possesses an IP technology[3] is an abundant technology address that can be employed by our pc or for communication, data transfer as well as mobile. So, that we can host or control the data management. But, none of us utilize prototype by means of such application the complete profit out of it rather than us. installed. By using these concepts, an RC car is built using wi-fi that is esp8266 NodeMCU[4] L298n MOTOR DRIVER in our research work we will see about the The L298n[5] is an H Bridge motor drive model and working of the car. which is used here. This motor drive contains many controls as motor A & B COMPONENTS USED controls. The thrust is always required for 1)NodeMCU a device to get it done. In that way, power 2)Breadboard and Wires paves a most vital role in terms of working 3)L298n Motor Driver of NodeMCU. It gives a better output if it 4) Wheels uses a varied power supply for two 5) 5-9V Power Supply components. We can apply any of the voltage levels such as 9v, 12v etc.

WORKING METHODOLOGY conditions. The working prototype of wi-fi controlled NodeMCU begins with connecting motors By means of certain application in a pc with wheels, a bit of soldering work which (or) mobile phone, we can connect the IP- includes motors to be connected to the address through which the car is being sockets of driver. Before connecting the controlled. In case, of any discrepancies, motor with the provided l293 driver, we we should check whether the power supply have a most significant principle to follow, is in a proper way. There may be any loose i.e. we should run the code before getting contacts with the soldering which is done. through the UNO. Then, we should check We should not overrate the power supply the mobility of the wi-fi controlled car’s more than 12v. That’s how this prototype forward, backward, leftward (or) rightward works.

The RC car is controlled by the address of the wi-fi module we can NodeMCU car application. This control our car. The screenshots of the application contains an IP address based app is given above and the circuit connection system. So by using our IP diagram is given below:
