Human Following Robot

Project Title

Human Following Robot

Project Area of Specialization RoboticsProject Summary

Robotic technology has increased appreciably in past couple of years. Such innovations were only a dream for some people a couple of years back. But in this rapid moving world, now there is a need of robot such as “A Human Following Robot” that can interact and co-exist with them. Hear after the name all the persons are thinking about the Robot what is it? And what does the meaning of this title? Will it really follow the humans? No this is basically the following robot that can follow anything. This Arduino robot having a sensor that can detect any object near it and can follow this object. If you come in front of the robot it will start following you. This robot consists ultrasonic sensor and ir sensor which help to follow the object.

Project Objectives

Humanoid robotics is an emerging research field that has received significant attention during the past years and will continue to play an important role in robotics research and many applications of the 21st century and beyond. In this rapid moving world there is a need of robot such an A Human Following Robot that can interact and co-exist with them. Because of its human or following capability, these robots can work as assistants for humans in various situations. The development of robot technology had increased significantly due to industrial, medical and military applications. In various fields with harsh environment such as underground mining, war-zones, medical, construction, space exploration etc. the work done by one is extremely dangerous. Life of individuals assisting are also put at risks. Tasks performed by humans have its own limitations in many ways. In order to perceive beyond the human limitation in vision, speed, consistency, flexibility, quality e.tc we should make use of robots. A key requirement for these robots is the ability to detect humans and to interact with the non-technical way. The main objective of this dissertation is to make a robot that can help humans with various task

Project Implementation Method

We have successfully made the human following robot which is used to follow objects as well as humans. This robot uses ultrasonic range sensors and Infrared sensors. The test was performed on the both ultrasonic sensor and infrared sensor that the sensor was working accurately within the range of 10 cm. An ultrasonic sensor is used to move the robot forward and backward. Infrared sensors are used to move the robot in the left or right direction accordingly. Then we test the serial communication of Arduino, motor shield, and various motors. This robot took a lot of time to complete this project. We were faced lots of problems regarding the program code, as there was huge numbers of error in the code which was further rectified it and lastly it works. Motors drivers connections got interchanged which was rectified and our robot works perfectly fine. Finally, after the lots of effort and time our objective was achieved which was to implement a good Human-Robot interaction

Benefits of the Project

Robots are artificial agents with capacities of perception and action in the physical world often referred by researchers as workspace. Their use has been generalized in factories but nowadays they tend to be found in the most technologically advanced societies in such critical domains as search and rescue, military battle, mine and bomb detection, scientific exploration, law enforcement, entertainment and hospital care. A robot which can help us in many fields like carrying items, work with more accuracy in lesser time in every kind of works. A robot that can help us in a hospital or bringing medical items in any emergency case will be more helpful for a doctor in emergency cases. This type of robot having so many benefits and it will be helpful in the future. This type of robot can be close to humans is much possible.

The human following robot can use in the defense sector also to carry weapons for the soldiers. This type of robot can sense obstacles and humans automatically and it can use in the future in our cars. A human following robot can be modified in the future with more developed components and can make it more advance. This robot can be enhanced by structure by adding more components like camera tracking device and make it more beautiful and workable. This robot will be more trend in our future

Technical Details of Final Deliverable

This is basically the following robot that can follow anything. This Arduino robot having a sensor that can detect any object near it and can follow this object. If you come in front of the robot it will start following you. This robot consists ultrasonic sensor and ir sensor which help to follow the object.

A robot which can help us in many fields like carrying items, work with more accuracy in lesser time in every kind of works.

This type of robot having so many benefits and it will be helpful in the future. This type of robot can be close to humans is much possible. This useful project is made to attempts to follow the right human or obstacle. In this robot, Infrared sensors are used to move the robot in both the direction and ultrasonic sensor for both the forward and reverse direction. We used the Arduino Uno microcontroller as the brain of this project. The main objective of designing this useful project is to make our life better and luxurious. In this project robotic car sense the human by IR sensor automatically and follow the human and obstacles. This type of robot will be more useful and it will be a trend in the future.

When you come near to the robot starts to follow you. There are 4 wheels in the robot. And 4 motors attached to the chassis. Now there are three sensors on the robot one is an ultrasonic sensor and two ir sensor which arranges like two or sensors left and right to the ultrasonic sensor. And 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 the Arduino robot moves on the left side, and if you put your hand in the right the robot will move in the right direction. So, how the whole system works we will talk about this.

When you put your hand in from of the ultrasonic sensor then the sensor detects you and sends this information to the Arduino. There is some distance prefix in the Arduino so if your hand is away from the sensor it will not read that. And if your hand is near to the sensor it will read it. Now Arduino knows that there is something in front of the sensor and Arduino send some instruction to the motor driver and motor driver trigger the motors. And the Arduino robot starts to move forward we need to run all motor forward.

Now, what about the sensors. Ir sensor works on infrared light which can also detect the object near to it. So there is two IR sensor one is at the left side of ultrasonic sensor and other is at the right side of the ultrasonic sensor. When anything comes near to the left sensor Arduino got the information that there is something is near to the left sensors and according to the code, the robot will turn to the left. And the same process for the right sensor. So this is how the human following robot works.
