1.1. Definition of Robotics

Robotics is the interdisciplinary branch of engineering and science that deals with the design, construction, operation, and application of robots. A robot is a programmable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions to accomplish a variety of tasks.

Robotics combines various fields of engineering and science to create robots, which are machines programmed to perform tasks. A robot is not just a simple machine; it can manipulate objects and perform complex functions due to its design and programming. Think of a robot as an advanced tool that can carry out tasks automatically once programmed, greatly enhancing efficiency in various fields, especially in industries like manufacturing and construction.

Imagine a robotic arm in an automobile factory. It can assemble parts of a car quickly and accurately. By programming this arm to perform specific tasks, it becomes a crucial part of the production line, just like a chef uses different kitchen tools to prepare a dish.

Key components of a robot include:

• Mechanical structure: Provides physical form and mobility.
• Sensors: Detect environmental and internal states.
• Actuators: Drive motion and interaction with the environment.
• Control systems: Interpret commands and sensor data to direct actuators.
• Power source: Provides energy for operation.
• Software/Programming: Defines behavior and task logic.

Every robot has several critical components that work together. The mechanical structure forms the robot's body and allows it to move. Sensors help the robot understand what is happening around it, like a human using their senses. Actuators are responsible for movement, similar to muscles in our bodies. The control system acts like the brain, processing information from sensors and directing the actuators. For a robot to function, it needs a power source, much like batteries that power electronic devices, and software that gives it instructions on how to perform tasks.

Think of a self-driving car. Its mechanical parts form the vehicle, sensors act like the car's eyes (detecting road signs and other cars), actuators steer and accelerate (like our legs and hands), and the control system processes all this information to navigate safely. The car’s software guides it on driving habits, such as stopping at red lights or yielding to pedestrians.

Types of Robots:

• Industrial Robots: Used in manufacturing lines (e.g., robotic arms).
• Service Robots: Assist in non-manufacturing settings (e.g., cleaning robots).
• Mobile Robots: Move through environments autonomously or semi-autonomously (e.g., drones, AGVs).
• Collaborative Robots (Cobots): Work alongside humans safely.

Robots come in various types, designed for different purposes. Industrial robots are often found in factories, performing repetitive tasks with high precision. Service robots assist in everyday tasks, such as cleaning or delivery. Mobile robots can navigate and explore their environment, either on their own or with some human direction. Collaborative robots, or cobots, are designed to work alongside people, aiding in tasks while ensuring safety through various features that prevent accidents.

Consider a restaurant. A cleaning robot may automatically sweep the floor while a humanoid robot serves food at tables, demonstrating the different roles robots can play in a single environment. Meanwhile, in a factory, a robotic arm might assemble parts, while another robot designed to work with human workers could assist in lifting heavy packages.
