Modules One - Three | Question Bank Answers

MODULE ONE: INTRODUCTION TO ROBOTICS

Q One. Define robotics and explain its interdisciplinary nature.

Definition: Robotics is the science and technology of designing, constructing, operating, and applying robots. The ISO defines a robot as a reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable programmed motions for a variety of tasks.

Interdisciplinary Nature: Robotics draws from three core engineering fields:

. Mechanical Engineering - deals with the motion subsystem: links, joints, actuators, transmissions, and the structural design of the manipulator.

. Electrical Engineering - handles the control subsystem: servo drives, sensors, signal conditioning, power electronics, and control algorithms (PID, etc.).

. Computer Science - responsible for the recognition subsystem: robot programming, Artificial Intelligence, vision processing, and decision-making software.

All three domains interact tightly: a mechanical arm is useless without sensors and a controller, and a controller is useless without a physical structure to move.

· Two thousands - Present: Collaborative robots (cobots), mobile robots, medical/surgical robots (da Vinci), space robots (Curiosity, Mangalyaan), service robots.

Q Four. List and explain the elements of a robotic system.

A robotic system has three major subsystems, each with specific elements:

One. Motion Subsystem

Two. Recognition Subsystem

Three. Control Subsystem

Fuller's Fourth Law (nineteen ninety-nine):

The Motion Subsystem is the physical structure that executes robot movement.
