What is Robotics?
Defining Robotics
Robotics is an interdisciplinary field that integrates computer science, mechanical engineering, electrical engineering, and other disciplines to design, construct, operate, and apply robots. At its core, robotics is about creating intelligent machines capable of performing tasks autonomously or with minimal human intervention. These machines are designed to mimic human actions, augment human capabilities, or even perform tasks that are too dangerous or repetitive for humans.
