Learning Robotic Process Automation

By: Alok Mani Tripathi

Overview of this book

Robotic Process Automation (RPA) enables automating business processes using software robots. Software robots interpret, trigger responses, and communicate with other systems just like humans do. Robotic processes and intelligent automation tools can help businesses improve the effectiveness of services faster and at a lower cost than current methods. This book is the perfect start to your automation journey, with a special focus on one of the most popular RPA tools: UiPath. Learning Robotic Process Automation takes you on a journey from understanding the basics of RPA to advanced implementation techniques. You will become familiar with the UiPath interface and learn about its workflow. Once you are familiar with the environment, we will get hands-on with automating applications such as Excel, SAP, Windows and web applications, screen and web scraping, working with user events, and we'll cover exceptions and debugging. By the end of the book, you'll not only be able to build your first software robot, but you'll also wire it up to perform various automation tasks with the help of best practices for robot deployment.

Types of OCR available

There are two OCRs available in our UiPath Studio:

  1. Microsoft OCR
  2. Google OCR

However, we are free to import other OCR engines into our project.

Both the Microsoft and Google OCR engines have their own advantages and disadvantages. The advantages of Google OCR include the following:

  • Multiple language support can be added in Google OCR
  • Suitable for extracting the text from a small area
  • It has full support for color inversion
  • It can filter only allowed characters

The advantages of Microsoft OCR include the following:

  • Multiple languages are supported by default
  • It is suitable for extracting text from a large area

OCR is not 100% accurate. It is useful for extracting text that other methods cannot successfully do. It works with all applications, including Citrix.

Microsoft and Google's OCRs are not the optimum for every situation. Sometimes, we have...
