     Mechatronics 2

    Mr. Wayne Williams

    Mechatronics Integrated Technologies 1-4
    (Activity Codes 6210, 6211, 6212, and 6213)
    PROGRAM DESCRIPTION
    Mechatronics is a new interdisciplinary field involving mechanical, instrumentation, electronics, robotics/automation, computer components, and control systems. The program prepares students who like to work with their hands as well as their minds. Mechatronics is a dynamic field that changes daily with the rapid improvements in technology and computer systems. Systems are networked to meet the demands of automated manufacturing processes, and technicians are trained to meet necessary entry-level industrial skills and entry into a postsecondary program at a technical college. Dual credit may be available through some SC technical colleges.
