IOT Based Spy Robot with LASER Gun And Fire, Gas Leakage Detection

  The project aims in designing a War field robot which is operated through smart phone wirelessly using IOT technology. This robot also shoots the enemy using the laser gun controlled by the user from mobile application through esp8266 Wi-Fi. It is a very low-cost robot used to monitor the Warfield. The robot can be moved in all the directions controlling from smart phone wirelessly. This robot can detect the GAS, FIRE using sensors and alerts the person through buzzer. 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 controlling device of the whole system is an Arduino uno Microcontroller. Here, Wi-Fi module, DC motor with driver, Flame sensor, Gas sensor, Buzzer and Laser gun is interfaced to the microcontroller. Whenever the user presses a button from mobile application by using smart phone, the data related to that button is sent through Wi-Fi. This data will be received by the esp8266 Wi-Fi module in robot section and fed as same to the Microcontroller which judges the relevant task to the information received and acts accordingly. LASER gun is placed on the robot to shoot the enemies, which can be controlled using mobile through Wi-Fi. When the robot detects the fire and smoke it will activate the buzzer for alerts. LM2596 is used to converts 12VDC to 5VDC for microcontroller working. The microcontroller is loaded with an intelligent program written in embedded ‘C’ language.  

The objectives of the project include:

• Design of real time robot.
• IOT based control of robot directions and movement.
• To shoot the enemies using laser gun.
• Automatic GAS/SMOKE detection.
• Automatic Fire detection.
• Fire and gas alerts using BUZZER.
• Using mobile application to control the robot along with laser GUN.
