Review on Long Range Solar Power Spy Robot

Abstract

A Spy robot is a machine which can be controlled by the cell phone. The cell phone has
twelve buttons to control the robot in four directions and also to perform other
functionalities. This spy robot holding four technologies together, they are- Human Motion
Detection using Passive Infrared Sensor, Metal Detection, Night Vision Wireless Camera and
LED Flasher. PIR sensor detects the changes in the IR levels emitted by the humans. It can
detect the levels of Infrared Radiations. Robot motion, Metal Detection, Night Vision
Wireless Camera and LED Flasher is done by DTMF Technology. The system used two
mobile phones, one to control the robot that sends DTMF commands via call to another
mobile phone mounted on the robot vehicle. A DTMF decoder, metal detector and LED
Flasher are interfaced with the microcontroller of 8051 family.
