3. Introduction In this high technology, a robot must be able to detect and follow humans. A robot that can detect and follow human or obstacle within a specific range is called ‘Human Following Robot’. The robot needs a mechanism which can make decision for it to take actions accordingly so that the task can be performed correctly. The involved mechanism is sensor that can detect obstacles or object around the robot itself In this project, Ultrasonic sensor is used. Ultrasonic sensor is a device that able to measure the distance to an obstacles by using sound wave

4. Scope Human following robots are currently being used in a number of areas in our world today. As well as being proposed for used in other sectors too. These sector include service areas,household,travel and shopping; Human following robot include detecting the target person,preventing permanent loss of the target person Determining the distance from detect person and navigating with respect to the target person

5. Objectives A Human following robot requires several techniques, such as Human target detection Robot control algorithm and obstacle avoidance.Various approaches of following robots have been proposed such as using ultrasonic sensor

7. Working When you put your hand near to the ultrasonic sensor the robot will start forward . And if you turn your hand to the left side Arduino robot moves one the left side, and if you put your hand in the right The robot will moves in the right direction When you put your hand in front of the left side of ultrasonic sensor then the sensor detect your hand send this information to arduino The two IR sensor, one is at the left side of ultrasonic sensor and other is the right side of the ultrasonic sensor

9. Hardware & Software Requirement Arduino uno IR Sensor Ultrasonic Sensor Servo motor Motor driven shield DC Gear motor Arduino IDE

10. Arduino Uno Arduino uno is microcontroller board based on ATmega328 It has 14 digital input/output pins, 6 analog input

11. IR and Ultrasonic sensor IR sensor Proximity sensor is used to detect object & obstacles in front of sensor Digital low output on detecting objects in front Ultrasonic sensor An ultrasonic sensor measures the distance if a target object by emitting ultrasonic sound waves For ultrasonic sensor range is 40 to 70 khz

12. Servo Motor Micro servo motor is a tiny and lightweight sever motor with high output power Servo can rotate approximately 180 degree

13. Motor driver shield & DC gear motor Motor driver shield Motor allows you to use Arduino to control the working speed and direction of the motor The motor driver shield can control four servo once DC gear motor A gear motor is a component whose mechanism adjust the speed of the motor

14. Arduino IDE The Arduino IDE supports the language C & C++ using special rules of code structuring The Arduino IDE supplies a software library from the wiring project , which provides many common input and output procedure

15. Advantages A Human following robot requires several techniques such as humans target detection,robot control algorithm and obstacle avoidance It can be used for home for floor cleaning In hotel they are being used for the transfer of things from one place to another following a straight path

16. Result When you put your hand near to the ultrasonic sensor the robot will start forward . And if you turn your hand to the left side Arduino robot moves one the left side, and if you put your hand in the right The robot will moves in the right direction
