Definition and Scope

Robotics encompasses the design, construction, operation, and application of robots—machines engineered to perform tasks traditionally undertaken by humans. This interdisciplinary field integrates principles from mechanical engineering, electrical engineering, computer science, and other disciplines to develop systems capable of autonomous or semi-autonomous operation in diverse environments.

Historical Development

The concept of automata dates back to ancient civilizations. Around 420 B.C., Archytas of Tarentum constructed a wooden, steam-propelled bird capable of flight. In the 15th century, Leonardo da Vinci designed a mechanical knight, an early humanoid robot. The term "robot" was introduced in 1920 by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots), depicting artificial workers. The mid-20th century marked significant advancements with the development of industrial robots like Unimate, the first programmable robot, which revolutionized manufacturing processes.

Core Components

Robotic systems typically consist of the following components:

• –

  Mechanical Structure: The physical framework, including joints, actuators, and end-effectors, enabling movement and interaction with the environment.

• –

  Sensors: Devices that gather information about the robot's surroundings or internal state, such as cameras, accelerometers, and proximity sensors.

• –

  Control Systems: Algorithms and software that process sensor data to make decisions and generate commands for actuators.

• –

  Actuators: Motors or other mechanisms that execute movements or actions based on control system outputs.

Types of Robots

Robots are categorized based on their design and application:

• –

  Industrial Robots: Utilized in manufacturing for tasks like welding, painting, and assembly. These robots enhance efficiency and precision in production lines.

• –

  Service Robots: Designed to assist humans in non-industrial environments, including domestic chores, healthcare, and customer service.

• –

  Medical Robots: Employed in healthcare settings for surgeries, rehabilitation, and diagnostics. Examples include surgical robots that perform minimally invasive procedures.

• –

  Autonomous Vehicles: Robots capable of navigating environments without human intervention, such as self-driving cars and drones.
