Mechatronics is a multidisciplinary field that combines mechanical engineering, electronics, computer science, and control engineering to create smart systems. These systems utilize integrated mechanical, electrical, and software components to perform a variety of tasks autonomously or semi-autonomously. Mechatronic components play a crucial role in the development of modern automation systems, robotics, automotive technologies, and consumer electronics.
Mechatronic components are the individual elements that form the backbone of mechatronic systems. They consist of mechanical, electrical, and computing parts that work together to enable a system to perform complex functions. These components include sensors, actuators, controllers, power electronics, and communication devices that help in designing and building smart, adaptive systems.
