Introduction

In recent years, the development of automation and monitoring systems has become increasingly important in various sectors, including security, agriculture, and environmental research. One of the key technologies used in these systems is Wi-Fi communication, which allows for real-time data transmission and control. In this article, we will discuss the design of a monitoring robot that uses Android smartphone control with a Wi-Fi communication system based on Nodemcu ESP8266.

Robot System Description

The monitoring robot designed in this project is equipped with two DC motor drivers that allow the wheel rotation settings. In addition, there is one additional driver that controls the direction of rotation in the camera drive. The use of Wi-Fi technology for communication is very effective, allowing robots and smartphones to be connected in real-time, so users can oversee the conditions around the robot efficiently.

The camera attached to the robot has the ability to connect to a laptop or PC through a Wi-Fi network. This camera not only serves to oversee the surrounding environment, but can also be used to take photos and record video as long as the robot operates. This provides added value to the function of the robot as a monitoring tool that can be used in various applications, such as surveillance, security supervision, or environmental monitoring.

Operational Resources and Power

This robot resource uses three 3.7 volt Li-ion batteries that are arranged in series to produce a total voltage of 12 volts. This voltage is then arranged using the IC Regulator 7805 circuit, which converts it to the 5 volt voltage needed to support the entire robot system. With an efficient power design, this robot can operate well in an adequate period of time.

Analysis and Profits

The use of Nodemcu ESP8266 in this monitoring robot not only provides convenience in control, but also increases flexibility and effectiveness in operation. Wi-Fi technology allows a much wider control distance compared to cable-based control systems or Bluetooth. By utilizing a smartphone, users can control without having to approach the robot physically.

In addition, the ability of the camera to take pictures and videos directly facilitate data collection and situation analysis in the field. This robot can be implemented in various sectors, ranging from security, agriculture, to environmental research, which makes it a very useful and multifunctional tool.
