With the emergence and growth of Industry 4.0 technologies, mechatronics is being used to design increasingly complex, interdisciplinary projects. Ideal for students in mechanical, manufacturing, and industrial engineering programs, Mechatronics for Complex Products and Systems takes a project-based learning approach to help students build the real-world skills they will need in their engineering careers. The first half of the book covers the different design principles for designing mechatronic systems, including axiomatic design, concurrent engineering, model-based design, and modularization, and breaks mechatronic systems down into functional modules like power systems, actuating systems, sensing systems, signal conditioning and processing, and control systems--the building blocks that engineers use when tacking real-world problems. Students will learn how to define the inputs and outputs of each functional module appropriately for the more complex products and systems that are explored in the latter portion of the book, such as cyber-physical systems, robotics, human-robot interactions, digital twins, brain-computer interface, and the metaverse. Project assignments incorporated throughout most chapters help reinforce a practical understanding of how to select the right type of sensors, motors, and controllers for different projects. Students will gain a better understanding of how to integrate a broad range of foundational knowledge to solve real-world engineering problems.
