Project Summary

In the industry, carriers are required to carry products from one manufacturing plant to another which are usually in different buildings or separate blocks. Conventionally, carts or trucks were used with human drivers. Unreliability and inefficiency in this part of the assembly line formed the weakest link. The project is to automate this sector, using carts to follow a line instead of laying railway tracks which are both costly and an inconvenience.

In Hospitals, Libraries, Airports and Hotels, there is a need of something to carry things from one place to another. To help workers in carrying load there is a need of such robot which can follow a person or guided through voice or controlled through android phone to help them

Our Robot have the following features;

• An obstacle Avoidance Human Following Robot.
• A Maze Solver Robot.
• An Object Follower Robot.
• A Voice Controlled Robot.
• An Android Phone Controlled Robot.

Project Objectives

• The field of robotics includes many branches of engineering including electronics, mechanical, digital logic, artificial intelligence, nanotechnology and bioengineering. A robot can do various types of work depending on what type of robot is being referred to. Some of them are simple and some are quite complex. Robots are designed to do tasks that people may or may not be able to do for them. They are used to build cars, dismantle bombs, pack boxes, answer phones, mow yards and explore deep sea ship wrecks and many other things.
• A robot might be designed to perform one particular task networks, software and accessories that increase their usefulness. They may recognize people or objects, human voice, provide companionship, monitor environmental quality, respond to alarms, pick up supplies and perform other useful tasks. Dedicated robots are designed for a particular work. Examples of Dedicated robot are Factory robots, Tele robots, Automated fruit harvesting machines, Domestic robots, Military robots, Rescue robots, playing robots, Mining robots, Virtual tutors, Healthcare, Teacher assistants, Research robots etc.
•  Many conventional robots are designed for a particular purpose or specific field of use. For two different types of works, two different types of robots may be required. This involves cost as well as increase complexity in coordination of different jobs of different robots. Hence, it will be more cost effective, if a multipurpose robot is designed that can perform multiple type of works assembled in a single platform. Such a multipurpose robot can perform multiple works simultaneously and thus save both cost and time. Hence, this work will focus on design and construction of a multipurpose robot.
•  It is always necessary to coordinate multiple robots or multiple works of a single multipurpose robot. This coordination is always a challenging job and proper operation of an integrated robotic system depends mostly on this part. Because a multipurpose robot includes various sensing and working modules that can work simultaneously and synchronously, it saves time and cost and at the same time works are done more efficiently.

Project Implementation Method

The main components that are used in our Multifunctional Robot are 4 TT Gear Motors DC 3V-6V, 4 Wheels, Arduino UNO, Motor Driver Shield L293D for Arduino and additional components are used in each function of our Multifunctional Robot whose description is given below.

In case of Human Following and Object Following Robot Function of our Multifunctional Robot, the additional Components that we have used are one ultrasonic sensor, two IR sensors, a servo motor SG-90. 
Working:
? When you put your hand near to the ultrasonic sensor the robot will start forward. As you turn your hand to the left side the Arduino robot moves to the left side and if you put your hand in the right the robot will move in the right direction.
? When you put your hand in front of ultrasonic sensor then the sensor detects you and send this information to the Arduino.
? The two IR sensor, one is at the left side of the ultrasonic sensor and other is on the right side of the ultrasonic sensor.
? When anything comes near to the left sensor Arduino got the information that there is something near to the left sensor and according to the code. The robot will turn to the left and the same process for the right sensor.

In the case of Maze Solver Robot Function of our Multifunctional Robotic Vehicle, the additional components that we used are one ultrasonic sensor and a Servo motor SG-90.
Working:
The maze solver robot continuously move forward until something come in front of ultrasonic sensor. When something come in front of ultrasonic sensor the robot stops moving and moves backward for some distance then the servo motor rotates 180 degree and check that is there any obstacle in the left and right of robot. When there is a obstacle in the right then the robot will turn towards left and when there is a obstacle in the left then the robot will turn towards right.

In case of Bluetooth Controlled Robot Function of our Multifunctional Robotic Vehicle, the additional components that we have used are HC-05 Bluetooth module.
Working:
We use APP Bluetooth RC Controller or BT Car to Connect the Robot with Android Phone. The Forward button will move the car towards Forward Direction. The Backward button will move the car towards Backward Direction. The Left button will move towards Left Direction. The Right button will move towards Right Direction.

In case of Voice controlled Robot Function of our Multifunctional Robotic Vehicle, the additional components that we have used are HC-05 Bluetooth module, one Ultrasonic Sensor, one IR sensor and a servo motor SG-90. This App use Google voice assistant to pass commands to Bluetooth module HC-05 to move the vehicle. We use ultrasonic sensor to stop the vehicle when if it is moving forward.

In case of Line Following Robot Function of our Multifunctional Robotic Vehicle, the additional components that are used are two IR sensors. When both the Ultrasonic sensor detects the black line then the Robot stops.

Benefits of the Project

• Looking deeply into environment or our surroundings, we were be able to interpret that there is a need of such robot that can assist humans and can serve them.
• Such a robot can be used for many purposes. With a few modifications, the robot can act as a human companion as well.
• These kinds of robots can help in carrying loads for people working in hospitals, libraries, airports etc.
• It can be used for home for floor cleaning. In hotels they are being used for the transfer of things from one place to another following a straight path.
