IOT BASED ANDROID CONTROLLED SURVEILLANCE ROBOT Vinayak Patil1,Chetan Petnekar1,Ganesh Chougala1,Omkar Sherekar1 1Student, Dept of Electronics & Communication, S.G.Balekundri Institute of Technology, Karnataka,India 2Assistant Professor, Dept of Electronics & Communication, S.G.Balekundri Institute of Technology, Karnataka,
India ---------------------------------------------------------------------***--------------------------------------------------------------------1.1 MOTIVATION Abstract - The rising need for secure and remotely controlled monitoring systems has raised the significance of intelligent surveillance systems [7]. In this paper, an IoTbased Android-controlled surveillance robot for real-time monitoring systems is discussed and demonstrated. The proposed work uses the ESP32-CAM module to stream realtime video streaming over the internet [1],[3],[6]. The Node MCU ESP8266 enables wireless communication between the robot controller and the Android app interface [2],[5]. The ultrasonic sensor enables the robot to detect barriers and navigate safely to the target destination [7]. The metal detector sensor enables the robot to detect metal objects in the environment and respond accordingly. The GPS module helps to track the real-time location of the robot. The robot can be controlled from any corner of the world using the Android smartphone device. The proposed robot systems can be applied effectively to dangerous and restricted areas [7],[8].
The need for implementing this system arises out of the fact that in environments where the presence of a human being might be dangerous or difficult to accomplish, there is a need for a safe and efficient surveillance system. In fact, the normal system of surveillance done in fixed environments requires a lot of manual observation and is therefore not so reliable or useful in a dynamic or dangerous setting like a surveillance mission or a restricted area inspection process or in a crisis or disaster scenario where continuous observation might be necessary. With improvements in IOT and mobile technology and its ability to implement intelligent robot platforms with real-time observation and controlling abilities, it is possible to work out a low-cost portable and friendly robot for surveillance purposes as a motivation to this project.

1.INTRODUCTION Recently, the demand for efficient and effective surveillance solutions has risen with increasing security concerns in both public and private sectors [7]. Existing surveillance solutions involve continuous human observation, which may not always be safe and efficient [7],[8], especially at security-critical sites. To overcome these drawbacks, IoT-based surveillance solutions have attracted considerable interest [2],[7]. These solutions support real-time observation and remote control with the help of internets connectivity. Robotics with embedded technology helps perform surveillance tasks at sites that are either difficult to reach or not safe for human entry [1],[6]. Wireless communication and sensing technologies together make the system more flexible and efficient. Visual observation with the help of cameras is an important component for providing vision support for decision-making purposes [3], [5]. Mobile solutions further make user interaction easier, allowing control and command from any corner of the world. Obstacles-sensing sensors assist safe movements for robotics. Position tracking provides an added benefit of security and accuracy for observation purposes. The proposed system will work on designing an effective and affordable surveillance robotics solution.

Surveillance at Surroundings
A great need exists for the development of monitoring systems capable of functioning in danger or non-accessible zones with minimal threat to human operators.
Real-Time Monitoring and Control Live video streaming with continuous monitoring and control through an android application are necessary for rapid decision-making. CostEffective and Scalable Solution The current stateof-the-art surveillance systems available may be costly; hence, there is a need for development in IoT-based robotic surveillance that is costeffective.
