Robotics and mechanisms

Definition

Robotics and mechanisms refer to the interdisciplinary field that involves the design, construction, operation, and use of robots and mechanical systems. This area combines principles of engineering mechanics, control systems, and computer science to create machines that can perform tasks autonomously or semi-autonomously. Understanding the equations of motion for rigid bodies is crucial in this context, as it allows engineers to analyze and predict how these robots will behave under various conditions.
