TRONICS)  The combination of mechanical and electronic systems.  Embracing robotics, industrial control systems and human interfaces in numerous disciplines, mechatronics is a major step beyond "electromechanical," in which only electricity is required.  Mechatronic systems employ microprocessors and software as well as special-purpose electronics.  The subhead of CMP's Mechatropolis website when it was in existence said "where mechanical and electronic engineering connect."  See 
animatronics and
