The main goal of this project is to design and develop a surveillance robot that can reduce the casualties in the war field. The robot movement can be controlled by the user by using android smart phone. This robot consists of esp32 camera which can be uses to send the live video to the user mobile over IOT. While seeing the video use can control the robot from web browser. The robot can perform multiple application such as if any bombs are placed at public places this robot acts as a bomb detector robot using the metal detector sensor and alerts though buzzer. The robot can be detecting the GAS and gives the audible alerts through Buzzer. The main controlling device of the project is ESP32 cam. To achieve this task microcontroller loaded program written in embedded C language.  

Objectives of the project:

• Enable real-time video surveillance of human activity in remote environments using the ESP32 Camera and web interface.
• Allow remote control of the robot's movements and actions via the web interface, enhancing its utility in military reconnaissance and surveillance operations.
• Developing a user-friendly web interface for controlling the robot and accessing surveillance footage, making it accessible to operators with minimal technical expertise.
• Sensor based automatic GAS, metal detection and alerting system.

        The major building blocks of the project are:  

• Battery power supply.
• ESP32 camera module.
• METAL DETECTION SENSOR.
• DC motors with L293d.
• Buzzer.
• GAS.
• LED indications.

  Software’s used:

• Embedded C programming.
• Arduino IDE programmer for dumping code into Micro controller.
• Express SCH for Circuit design.
• IOT technology.
