This document describes a project to develop a human detection robot using an RF module. It includes an introduction, requirements, features, block diagram, components like the Arduino microcontroller, crystal oscillator, helical gear motor, PIR motion sensor, advantages, disadvantages, applications, and conclusion. The robot uses a PIR sensor to detect human presence and an Arduino microcontroller connected to an ESP8266 WiFi module to control motors and receive commands over the internet. When a human is detected, an alert is given. The conclusion states that the human detection robot was successfully designed and tested by integrating the hardware components.

8. ARDUINO MICROCONTROLLER
 Arduino microcontroller is based on UNO
AtMega328.
 It is used to receive commands sent by the user via
the internet and processes according to the code and
also used to control the motors.
 Wi-Fi module ESP8266 is also connected with
the arduino so that Wi-Fi facility can be provided to
the robot.

9. CRYSTAL OSCILLATOR
 A crystal oscillator is an electric oscillator type
circuit that uses a piezoelectric resonator, a crystal, as
its frequency-determining element.
 To provide a stable clock signal for digital integrated
circuits, and to stabilize frequencies for radio
transmitters and receivers.
 Crystal oscillators are having a frequency range from
32khz to 200mhz

10. HELICAL GEAR MOTOR
 A unit which creates mechanical energy from electrical
energy and which transmits mechanical energy through the
gearbox at a reduced speed.
 A gearhead and motor combination to reduce the speed of the
motor to obtain the desired speed or torque.

11. PIR MOTION SENSOR
 1,Wide Working Voltage Range: DC 4.5V- 20V
 2,Detection Distance: 3 to 7m (can be adjusted)
 3,Blockade time: 2.5s (Default)
 4,Work temperature: -20-+80°C

12. ADVANTAGES
 Less man power.
 Saves human lifes.
 Ranges upto 30HZ-300GHZ.
 Fast in response.
 Easy to maintain.

13. DISADVANTAGES
 Not easy to operate on uneven surfaces.
 Only skilled person can be control.
 Voice command is absent.

14. APPLICATIONS
 Used in military frequencies.
 Used in wars.
 Used in army bases to find hidden
terrorists in buildings.

15. CONCLUSION
 The project “HUMAN DETECTION ROBOT” has been
successfully designed and tested.
 Integrating features of all the hardware components used have
developed it.
 Presence of all reasoned out and placed carefully thus
contributing to the best working. The controller makes use of a
PIR based input sensor to sense the human being and give us
an alert indication.
 Also use of a remote which is used to control the robot.
