Chapter 1: Introduction to Robotics and Automation

Abstract:

Robotics is a field of engineering that involves designing, building, and using robots. Automation is a broader concept that uses technology to perform tasks without human intervention. 

Robotics definition:

• Robotics combines mechanical engineering, electronics, and computer science. 
• Robots are programmable machines that can perform tasks autonomously or semi-autonomously. 
• Robots can be used for many purposes, including manufacturing, healthcare, transportation, and entertainment. 

Automation definition:

• Automation uses technology to perform tasks automatically, without direct human intervention. 
• Robotic Process Automation (RPA) is a technology that uses artificial intelligence, screen scraping, and workflow automation. 

History of robotics:

• The word "robot" comes from the Czech word robota, which means "forced labor". 
• The first industrial robot was developed in the United States in 1954 by American inventor George Devol. 
• Joseph F. Engelberger, an American physicist, engineer, and businessman, is known as the "Father of Robotics". 

So let's explore the Chapter 1 in details

1.1 Introduction

Robotics and automation have become fundamental to modern industries, revolutionizing how tasks are performed across various domains, from manufacturing to healthcare. Robotics involves the design, construction, and operation of robots, while automation focuses on using technology to perform tasks with minimal human intervention. Together, they drive efficiency, precision, and innovation in multiple fields.

This chapter provides an introduction to robotics and automation, covering their definitions, origins, history, key terminologies, and the emergence of the discipline as a crucial part of technological advancement.

1.2 Definitions of Robotics and Automation

1.2.1 Robotics

Robotics is an interdisciplinary field that integrates mechanical engineering, electrical engineering, computer science, and artificial intelligence to design and develop robots. According to the Robotics Industries Association (RIA), a robot is "a reprogrammable, multifunctional manipulator designed to move materials, parts, tools, or specialized devices through variable programmed motions for the performance of a variety of tasks."

1.2.2 Automation

Automation refers to the use of technology to perform tasks without direct human involvement. It encompasses a wide range of applications, from simple mechanical devices to complex artificial intelligence (AI)-driven systems. The International Society of Automation (ISA) defines automation as "the creation and application of technology to monitor and control the production and delivery of products and services."

1.3 Origin and History of Robotics and Automation

The history of robotics and automation dates back centuries, evolving from simple mechanical devices to highly advanced AI-driven systems.

1.3.1 Early Mechanical Devices (Ancient to Medieval Period)

• The earliest known concept of automation can be traced to Greek and Chinese civilizations.
• Around 300 BC, the Greek mathematician Ctesibius designed self-operating water clocks.
• In the 9th century, Muslim engineer Al-Jazari described automated machines, including water-powered clocks and humanoid figures.
• Leonardo da Vinci designed a humanoid automaton, the "Mechanical Knight," in 1495.

1.3.2 Industrial Revolution (18th - 19th Century)

• The invention of steam engines and mechanized production systems led to the first wave of industrial automation.
• In 1801, Joseph Marie Jacquard introduced the programmable punch card system in textile looms, an early form of automation.
• Henry Ford revolutionized manufacturing by introducing the moving assembly line in 1913, increasing production efficiency.

1.3.3 The Birth of Modern Robotics (20th Century)

• The term "robot" was first introduced by Czech playwright Karel Čapek in his 1920 play R.U.R. (Rossum’s Universal Robots).
• In 1956, George Devol and Joseph Engelberger created the first industrial robot, Unimate, which was later used in General Motors' production line in 1961.
• The development of microprocessors in the 1970s enabled more advanced automation and robotics.
• Japan became a leader in robotics in the 1980s, with companies like FANUC and Honda pioneering robot manufacturing.

1.3.4 AI and Robotics Revolution (21st Century - Present)

• The integration of AI, machine learning, and IoT has expanded robotics applications beyond industrial automation.
• Collaborative robots (cobots) have emerged to work alongside humans in industries.
• Robotics is now widely used in healthcare, space exploration, agriculture, and autonomous vehicles.
• The rise of Industry 4.0 and smart automation is driving future advancements.
