CIt has an ESP32 camera mounted over it, through which we will get live video feed and the interesting part here is that we can control and move this robot from a web browser over the internet. The ESP32 cam will capture live data with regards to its surroundings and then send it to a particular IP address through internet. User can access this device using mobile phone and while seeing the video user will control the robotic vehicle. This is the internet of things (IOT) based project, where we are particularly uses the Esp32 camera, metal detection sensor, buzzer and two DC motor along with l293d motor driver with Robot chassis is interfaced to the arduino. The controlling device of the whole system is arduino Microcontroller. Whenever the user presses a button from web page, the data related to that particular button is sent esp32 camera module. This data will be received by arduino microcontroller which judges the relevant task to the information received and acts accordingly on the robot movement. Here we are using DC motors to moving the robot like left, right and front, back.  When the metal detection sensor detects the metal, it will send to the arduino microcontroller then the microcontroller will activate the buzzer for alerts and sms alerts.  

The objectives of the project include:

1. Controlling robot from remote places.
2. Using esp32 camera for live streaming and to achieve this task.
3. Using DC motors to moves the robot.
4. Using IOT technology.
5. It alerts the person if it is detect metal using sensor.
6. Metal detection in war.
7. Audible alerts using Buzzer.
8. Sms alerts.

    The major building blocks of this project are:

• Battery
• Arduino uno
• ESP32 Camera.
• DC Motors with L293D driver.
• Metal sensor.
• Buzzer
• Gsm

  Software’s used:  

1. Arduino IDE studio compiler for dumping program.
2. Express SCH for Circuit design.
