Smart IOT-Powered Surveillance Robot with Multi-Application Capabilities

In an era where safety, automation, and environmental awareness are increasingly vital, the demand for intelligent, multi-functional robotic systems has grown substantially. This paper presents the design and implementation of an IoT-enabled surveillance and environmental monitoring robot aimed at addressing key challenges in security, safety, and remote observation. The proposed system includes a combination of microcontrollers Arduino Uno, ESP32-CAM, and ESP8266 that coordinate essential functionalities such as real-time object detection, live video streaming, metal detection, and air quality monitoring. It features an ultrasonic sensor for obstacle detection and servo motors for directional control, ensuring autonomous mobility and accurate navigation. Environmental conditions are monitored using an MQ-2 sensor for gas and air quality, while a relay-controlled water pump provides fire suppression or irrigation capabilities. Wireless communication is achieved through the Blynk IoT platform, enabling real-time remote control and data visualization. Designed to be adaptable and cost-effective, this robotic system is well-suited for industrial monitoring, environmental assessment, and public safety applications. The results highlight its potential as a scalable, intelligent platform that integrates security, automation, and sustainable technology.
