What is Robotics?
Robotics is the science and engineering of designing, building, and operating robots—programmable, automated machines capable of performing specific tasks with high precision and accuracy. Robots range from industrial arms in factories to autonomous drones and humanoid assistants, equipped with sensors, actuators, and control systems to interact with their environment. Robotics combines mechanical engineering, electronics, computer science, and AI to create machines that can move, sense, and make decisions, often reducing human effort or risk in complex tasks.
A Brief History of Robotics
The concept of robotics dates back to ancient times, with early automatons like the mechanical figures of ancient Greece. The term “robot” was coined in 1920 by Czech playwright Karel Čapek in his play R.U.R. (Rossum’s Universal Robots). The 20th century saw significant milestones: the first industrial robot, Unimate, was introduced in 1961 by General Motors for assembly line tasks.
The 1980s and 1990s brought advancements in sensors and computing, enabling robots like NASA’s Mars rovers. The 2000s marked the rise of consumer robotics, with products like Roomba vacuum cleaners. Today, robotics leverages AI, machine learning, and 5G, with companies like Boston Dynamics and SoftBank developing sophisticated robots for diverse applications. The global robotics market is projected to exceed $100 billion by 2030, reflecting its growing influence.
