What is Robotics?
Robotics is an interdisciplinary field that integrates mechanical engineering, electrical engineering, computer science, and artificial intelligence to design, construct, operate, and use robots. A robot is a programmable, multi-functional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions to accomplish a variety of tasks.
The word "robot" was first introduced by Czech playwright Karel Čapek in his 1920 play R.U.R. (Rossum's Universal Robots), derived from the Czech word robota meaning "forced labor" or "drudgery." Since then, robotics has evolved from science fiction into one of the most transformative technologies shaping our world.

Robotics in Industry: The Four Industrial Revolutions
The integration of robotics with industry has been shaped by successive industrial revolutions:
Industry 1.0 (1760s–1840s): Mechanization through water and steam power. Textile mills replaced hand weaving — early automation concepts.
Industry 2.0 (1870s–1914): Mass production enabled by electricity, steel, and assembly lines. Henry Ford's moving assembly line (1913) was a precursor to robotic automation thinking.
Industry 3.0 (1960s–1990s): Electronics, computers, and early automation. Industrial robots like Unimate transformed automobile manufacturing. PLCs (Programmable Logic Controllers) enabled flexible automation.
Industry 4.0 (2011–present): Cyber-physical systems, IoT, AI, and robotics converge. Smart factories, digital twins, autonomous mobile robots (AMRs), and collaborative robots (cobots) define this era.
Industry 5.0 (emerging): Human-robot collaboration at its core, with emphasis on sustainability, resilience, and human-centric automation. Robots augment rather than replace humans.
