Advancements in semiconductor and integrated circuits manufacturing led to the development of a new class of products that incorporated mechanical and electronics in the system and required the two together for their functionality. Mechatronics is the advanced engineering design that involves development of products and processes that involve a synergistic integration of mechanical, electronics and intelligent computer control systems in their operation


The Japan Society for the Promotion of Machine Industry (JSPMI) classified mechatronics products into four categories as follows: (i). Primarily mechanical products with electronics incorporated to enhance functionality. Examples include numerically controlled machine tools and variable speed drives in manufacturing machines (ii). Traditional mechanical systems with significantly updated internal devices incorporating electronics. The external user interfaces are unaltered. Examples include the modern sewing machine and automated manufacturing systems. (iii). Systems that retain the functionality of the traditional mechanical system, but the internal mechanisms are replaced by electronics. An example is the digital watch (iv). Products designed with mechanical and electronic technologies through synergistic integration. Examples include photocopiers, intelligent washers and dryers, rice cookers, and automatic ovens. Today the advent of microcomputer, embedded computers, and associated information technologies and software advances have resulted in speedy evolution in engineering design and application of the concept of mechatronics. This cuts across all the conventional or the so called traditional engineering disciplines.

Mechatronics Engineering is applied to nearly all aspects of real life situations and problems. These include but not limited to: Computer Integrated manufacturing, Transportation applications in high speed trains, modern automobiles, unmanned land vehicles, Smart robotics (for agriculture, sanitation, space exploration, mining, forestry, military, rescue, entertainment, music, medicine, etc.). Unmanned aerial vehicles used for different purposes e.g. military, monitoring, agriculture, etc. For example, modern automobiles contain about 30–60 microcontrollers and with the drives to develop modular systems for plug-n-play mechatronics subsystems. Where as in the early stages of automobile design, radio was the only significant electronics and the other functions were entirely mechanical or electrical. In the field of engineering agriculture, there is the precision agriculture where different types of precision equipment, automated guided vehicles and unmanned aerial vehicles are used for wide range agricultural operations, from land preparation, planting, weeding, chemical application, harvesting, to all forms of post harvest operations and processes


The focus of this research group is to identify and harness the potentials of mechatronics philosophy in developing products and processes with maximum possible local content for advancing the economy of Nigeria, through mechatronics research and development.
