Two Wheeled Self Balancing Robot Minor Project Synopsis

Introduction

The basic working principle behind a self-balancing robot is an inverted pendulum concept model in control theory, according to which the robot drives the wheels in the direction in which it tilts. Examples of the inverted pendulum in certain real applications include rockets like MAXUS, Segway the personnel transporter, and a self-balancing vehicle.

It has great advantages like small size, flexibility, and low cost because of these advantages, it can be used in various applications in the field of control engineering. The inherent complexity associated with the control of this platform finds its application in the design and development of control systems for automobiles, spacecraft, and transportation facilities including military transport.

The developed hardware is used to develop an object-carrying vehicle that can be used to reduce human efforts in working places, offices, and household applications.

This is a cost-effective solution using the PID algorithm for these two-wheeled vehicles.

Rationale

Because of the previously stated advantages that come with a two-wheeled self-balancing design, a number of consumer products have recently gone mainstream that utilize a similar idea for purpose of convenient human transportation, i.e. – Hover-boards, Segway, and self-balancing two-wheelers. Our goal with this project was to demonstrate the balancing mechanism used in these products in a compact, cost-effective prototype of a self-balancing robot.

Objectives

1. To balance the whole body on two wheels automatically by designing the best possible structure for the body and obtaining the filtered values from the gyro and accelerometer sensor i.e. – mpu6050.
2. To use inbuilt Wi-Fi or Bluetooth capabilities of ESP32 microcontroller to communicate with the robot in order to de- liver the commands to follow.
3. To fine-tune custom PID values for the robot to ensure its smooth maneuverability.
4. To generate the ability to balance and maneuver with objects placed on its head

Feasibility Study

1) Feasibility of the project

The project is intended to explain the design along with the construction and control mechanism of a two-wheel self-balancing robot. To deal with the problem of sudden horizontal movements and gyro drifts in sensors, a complementary filter is implemented[1]. PID (proportional integral derivative), is the feedback mechanism used for this project.

2) Need of the project –

1. Its ability to turn on the spot and sustainable architecture increases its applications in industries.
2. It is essential for the robot to not only balance but also maintain its position, withstanding external forces or unexpected disturbances if any

3. Active research on two-wheeled robots has been widely increased since the early versions of the studies on self-balancing robots by JOE and n-BOT.

3) Significance of the project –

These robots can be used for

1. Smart gardening purposes.
2. Autonomous trolleys in malls, hospitals, and airports.
3. An intelligent robot for various industrial-military purposes.

4. Currently popularized as “Segways,” these machines are mostly used for travel and tourism purposes and by private security services. It has been put to use by a range of private and military organizations since its invention.

Methodology/ Planning of work

The main objectives of a system for Online voting system are:

1. The objective of the Online voting system is to help the organization in automating the whole manual processing of the existing system.
2. Test the working and compatibility of all electronic components (mpu6050 and motors and its driver) with ESP32 separately and ensure the proper working of each component. a rudimentary prototype using all components with temporary wiring on the breadboard in order to test the integrated working of the components with each other (without tuning PID values).

  • This could help them to be updated with all the information regarding academics and fees/salaries etc.
  • Instead of finding receipts of fees or salaries, which may take hours, now it could be easily generated in a fraction of a second.

Challenges

  • It was difficult to merge different individual classes into a single large program as it undergoes inheritance and also variable scope gave us errors.
  • We also had some problems while formatting Marksheets and Certificates as it includes various types of ASCII characters.
  • We also had File Handling as our biggest Challenge. For eg., While getting information from the file we had many errors like the number of columns not matching in File and Program.
  • Along with that Modifying Information in files like Changing Fees after Paying Pending Fees was a difficult task for us.

Conclusion

  • We Learnt How To Make Real Life Applications with C++
  • Different concepts we learned are :
  • INHERITANCE (Single & Multiple Inheritance )
  • FILE MANAGEMENT
  • LOOPING STRUCTURE (FOR and WHILE)
  • CLASSES & OBJECTS
  • other Concepts Like SWITCH, GOTO, Simple IF…ELSE

Online Shopping Management System Java Console Application

This Project simulates the working of an online shopping portal where customers can buy products. Our Online Shopping Management System project is a purely console-based application and is implemented using the programming language JAVA.

This Java Console Application contains mainly two panels :

  1. Admin Panel – functions provided like managing products and customers
  2. Customer Panel – functions provided like buying products and making payments

A total of 8 class files have been created which are :

  • Database connection.java
  • Shop.java ( This is the main or the starting point of the project )
  • Admin.java
  • Customer.java
  • Products.java
  • Cart.java
  • Payment.java
  • Bills.java

Java Concepts used in the project are :

  • String manipulations
  • Collections framework in form of ArrayList
  • JDBC
  • Exception Handling
  • Inheritance
  • Classes and Objects
  • BufferedReader for taking entry

ROLE OF EACH MEMBER IN THE PROJECT

  • Designed class files – DatabaseConnection.java, Shop.java, Admin.java, and Customer.java and contributed to Debugging
  • Designed class file – products.java and contributed to Debugging
  • Designed class file – bills.java and contributed to Debugging
  • Designed class files – Payment.java and Cart.java and contributed to Debugging
  • Combination of class files in the end and for their joint working, Each member contributed equally.

DETAILS OF CLASS FILES

MAIN CLASS ( superclass ) = Shop.java

SUBCLASSES of Shop.java = admin.java and customer.java

Shop.java :

Main functions = registration of customer or admin, login into system Entry through buffered Reader

Array List used in login function to store id, password, and user type ( C for the customer, A for admin ) as a list

Database tables used are login info, admin info, and cast info Login info = storing used id, password, and type of user Admininfo = storing all details of admin except password Custinfo = storing all details of the customer except password setUID() function sets the admin ID to store in database setCUID() function sets the customer ID to store in the database.

Admin.java 

Functions include managing products (add,delete,view,search) by calling productsPage() function of products.java

Other functions include adding customers, removing customers, editing profiles, view registered customers.

For registering customers, since admin.java is subclass of Shop.java , registerCustomer() function of Shop is called by Shop.registerCustomer(), hence the small use of inheritance is here as the function need not be rewritten.

Customer.java :

Database table custinfo accessed for editing profile function

The main functions are viewing products, searching for products, adding and removing products from the cart, view the cart, and proceeding to the payment function.

Here first initializeProducts() function is called to store all product info in array lists, so that database need not be accessed everytime, hence Concept of collection framework is used here in form of ArrayList and through ArrayList functions .add(), .get(), .clear()

.add() = to add to ArrayList

.get(int i) = to get the element stored at index i in the ArrayList

Proceed to payment function calls payment.java class file and functions like add to cart, remove from the cart, and view cart call Cart.java. Calling is done via class objects like customerCart and p.

customerCart = object of Cart class p=object of Payment class

Customer.java is also the subclass of Shop.java where it calls the registerCustomer() function of the Shop.java through Classname.methodname like Shop.registerCustomer()

Products.java :

The main functions are added, removing, altering product info, viewing, and searching products setPid() function is used to set product id to store in the database

database table products are accessed to add, remove and alter product info

Cart.java :

This class file contains functions of the cart like add to cart, view cart, remove the product from the cart and cancel cart which is called from the customer.java class file via object.

Here add to cart function gets the product details to be added from customer.class via the constructor and adds them to the ArrayList so that the ArrayList can be used later on for displaying cart details and other functions as required.

Payment.java :

The main function of the payment class is to display bills and pay bills by calling bill.java, therefore it is an intermediate class between customer.java and bill.java and this class also stores payment details like bill and card details.

Bill.java :

Bill. class is called from the payment page through an object, this class contains details of a bill like a billing id, products purchased, and total amount. It also contains customer details whose bill it is. It stores the product details that are purchased in the ArrayList for easy access later on.

It contains functions like :

Generate bill = for calculating and storing the total amount in a variable Set bill id = for setting the bill id

Display bill = for displaying bill details

addtoDatabase = to add bill details to database table bills.

DatabaseConnection.java :

 The database connection is a class file that is used to establish a connection with the MySQL server and to create a database “Onlineshop” and five tables – login info, admin info, bills, products, and cast info. It takes the help of a flag variable to check whether the database schema exists or not and if exists, it only connects Java to MySQL.

It is imported into the class files like Shop.java and products.java where it is used to access the database and make connections.

Exceptions that are used in the project are :

  • IOException: This exception is used wherever BufferedReader has been used.
  • For handling the exceptions caused due to database like

ClassNotFoundException or SQL Exception, a try-catch block has been added.

  • For any other type of exception, sufficient try-catch blocks have been added.

Exception Handling features that are used in the project are :

Try-Catch block

Exception class functions like printStackTrace() have been used

throws keyword has been added in those methods wherever an exception is thrown and not handled by the method itself.

Snapshot of DatabaseConnection.java where Exception handling is used.

COLLECTION FRAMEWORK USED IN THE PROJECT

The concept of collections framework is used in the project through the implementation of ArrayList .

Use of ArrayList in the project :

Array List is used in the project to store the fetched results from the database for easy access later on. ArrayList is used in many class files in the project, like in customer.java , available product details are fetched from the database and stored in the ArrayList so that whenever the customer tries to access product info, it is fetched from the ArrayList and not from the database which reduces the complexity of code and saves time.

For using ArrayList Wrapper classes used are :

  • Integer for storing integers
  • Float for storing float values
  • String as a class for storing String values

DATABASE SCHEMA USED IN THE PROJECT

Here, the concept of JDBC comes into the picture and is implemented using MySQL and JAVA. The database is used in the project for storing information about admins, customers, products, bills, and login details.

Database details are as follows :

Name of the database = Onlineshop

The tables used in the project are :

  • Login Info Table
  • Admin Info Table
  • Cust Info Table
  • Products Table
  • Bills Table

How connectivity to MySQL was done :

 To connect to the MySQL server, we have used the JDBC concept and used the SQL Driver class to connect to the MySQL database. For using the SQL Driver class and other classes used for connection, java.sql.* is imported into the java class file.

Creation of the database and creation of tables were made in the DatabaseConnection.java class file and to access the database, later on, the code written was :

Class.forName(“com.mysql.jdbc.Driver);

Connection con=DriverManager.getConnection(String URL,username,password);

SOME SNAPSHOTS OF PROJECT OUTPUT

Main Page :

Customer section :

Some important points regarding the project :

  • The connector jar file should be added to the “Java project” using :
    JRE System Library > Build Path > Configure build path > Libraries > Add External JARs
  • For connecting to the database used in the project, enter the root password of MySql

Audio Classification On Cat’s And Dog’s Python Project

Our Audio Classification project illustrates a straightforward audio classification model supported by deep learning. we tend to address the matter of classifying the sort of sound-supported short audio signals and their generated spectrograms, from classifying dog’s audio to cat’s audio throughout model training. So as to satisfy this challenge, we tend to use a model-supported Convolutional Neural Network (CNN). The audio was processed with Mel-frequency Cepstral Coefficients (MFCC) into what is unremarkably called Mel spectrograms, and hence, was reworked into a picture. Our final CNN model achieved 89% accuracy on the testing dataset.

Project Overview :

The input to our model, in this project, is cats and associated dogs recording audio go in WAV kind. It lies below the supervised machine learning class. Thus, a dataset is also present as well as a target class. Hence, the intention here is to classify if the given input wav file is that of a cat or dog. Each of the dog and cat sounds is incredibly distinguished like in their pitch and frequency level since completely different| sounds have different sample rates. By default, Librosa mixes all audio to mono and resamples them to 22050 cycles/second at load time. For music and audio analysis, Librosa is associated ASCII text file python package. The info and the sampling rate are provided by Librosa. Audio or sound is in its raw kind, and the data provided should be pre-processed to extract significant and meaningful features so we implemented an algorithm i.e., MFCC (Mel Frequency Cepstral Coefficients) rule. Then, when audio extraction is done, the information is fed and the dataset is split into training and test set. So, after the preprocessing, a Convolutional Neural Network model is designed using tensor flow. For every code and model building, Keras API was used to implement Google colab.

Motivation

Machine learning can be used in image processing, understanding speech, and musical instruments, speech-to-text, environmental sound classification, and many more. And as for our project, we implemented a class of speech processing i.e, audio classification. Converting sound waves into audio and spectrograms which is a visual representation of frequencies with the help of function provided by machine learning.

There are many techniques to classify images as many different in-built neural networks under CNN are already there, especially if it is related to images. And it’s straightforward to extract options from pictures as a result of pictures already being available in the shape of numbers, because the formation of a picture may be an assortment of pixels, and pixels area units within the sort of numbers. When we have data as text, we use the sequential encoder and decoder-based techniques to find features. But if it is to sound recognition or audio it is more difficult compared to text because it is based on frequency and time. Therefore a proper model is to be made to extract the frequency and pitch of that audio so as to make it easier to later recognize it.

Preliminaries and Background 

Related work

Machine learning: Image classification of cats and dogs – Before a decade, in computer notion, many problems had been saturating in accordance with their precision. However, the accuracy of those troubles significantly stepped forward with the boom of deep gaining knowledge of strategies. The majority of the problems that arise from image class is that it is defined as predicting the distinct categories a photo can belong to. Hence, for the supplied enter/ photograph detection with the aim of accomplishing high precision, a state-of-the-art approach is incorporated, i.e., a convolutional neural network turned into the build for the photo category mission of puppies and cats. A dataset become given from Kaggle comprising a total of 25000 pix of each dog and cat.

Machine learning: Audio classification of different bird species – Here, the methodology and results of using deep learning to assist in the classification of birds by their sounds are presented. As birds indicate the health of an ecosystem, hence this topic is of high importance. Random Forest Classification and custom-made six CNN models from the literature were performed on a dataset of ten birds that were composed of xeno-canto.org. The highest accuracy was achieved at around 65% by the Random Forest and at about 58% for the CNN model.

conclusion and future work 

In this report, we first briefly explained the overview of this project and showed some referred project work already established. Then, we precisely illustrated our task, including the learning task and the performance task. After that, we explained the approach we are heading toward in order to classify the datasets. The approach/model we used is a neural network which is an implementation of the deep network which is a trainable model by which we were able to classify the dog’s and cat’s audio. The highest accuracy we got was 89.6%.

  1. In the future, we will try to implement the different high-level models in order to achieve much higher
  2. We’ll build a system that can directly intake a live raw
