Introduction to MechatronicsEEE436
Definition of MechatronicsMechatronics basicallyrefers to mechanicalelectronic systems andnormally described as asynergistic combination ofmechanics, electrical,electronics, computer andcontrol which, whencombined, make possiblethe generation of simple,more economic, and reliablesystems.The term "mechatronics" was first assigned by Mr. Tetsuro Mori, asenior engineer of the Japanese company Yaskawa, in 1969.
