The project aims in designing robot for patrolling which moves towards the sound using sensors and Arduino UNO. This project makes a use of four Sound sensors which are attached to the four sides of robot which is used to detect the sound from surroundings. DC motors along with l293d driver is used to moves and change the directions of robot. GPS module is used to track the location. Esp8266 wi-fi module is uses for sending the alert mail through wi-fi. Wi-Fi (Short for Wireless Fidelity) is a wireless technology that uses radio frequency to transmit data through the air. Wi-Fi has initial speeds of 1mbps to 2mbps. Wi-Fi transmits data in the frequency band of 2.4 GHz. It implements the concept of frequency division multiplexing technology. Range of Wi-Fi technology is 40-300 feet. The main controlling device of the project is Arduino UNO. ESP8266 wi-fi module, GPS, four sound sensors and DC motors along with L293d motor driver is interfaced to the Arduino UNO. When the sound sensors detect the sound this data process to the Arduino then Arduino will move the robot towards the sound and take the location from GPS module and also sending alert mail along with location to the registered mail ID through ESP8266 WI-FI module. To achieve this task arduino UNO loaded program written in embedded C language.

 

  The Major building blocks of this project are:

• Arduino UNO.
• DC motor with L293D motor driver.
• Four sound sensors.
• ESP8266 WI-FI module.
• GPS.
• Rechargeable Battery.
