Robotics & Automation


Robotics & Automation

Robotics and automation are interconnected fields that focus on designing, creating, and using machines and systems to perform tasks—often with minimal or no human intervention. They are key drivers of modern industry, manufacturing, and even daily life.

Robotics deals with the creation and use of robots—programmable machines capable of carrying out physical tasks, often mimicking human actions or performing beyond human capabilities.

Automation refers to the use of control systems, software, and technology to operate equipment, processes, or systems automatically, without continuous human input.
