Mechatronics: Introduction to Mechatronics

Mechatronics has been defined in many different ways over the years. Definitions
include *“incorporating electronics more and more into mechanisms,” *“the integration
of mechanical engineering with electronics and intelligent computer control in the
design,” and *“the application of complex decision making to the operation of physical
systems.” In essence, mechatronics is adding intelligence to a mechanical design or
replacing mechanical designs with an intelligent electronic solution. As technology
advances, designs that were once purely mechanical are now best done with electronics
or a combination of both. A good example of mechatronics that you are probably
familiar with is your thermostat at home. Mechanical thermostats typically had 2 to 3
degrees of error and could not be programmed for different temperatures throughout the
day. The only way to adjust the temperature setting of a mechanical thermostat is to
walk over to the thermostat and turn the dial. Modern thermostats are digital. These
thermostats are more accurate and are typically programmable, allowing you to save
energy when you are away from home. Although digital thermostats are usually more
expensive than the mechanical thermostats of old, a digital thermostat will pay for itself
very quickly in the energy cost it saves you. In addition, digital thermostats have push
button controls and a digital readout that consumers like. So in the case of the household
thermostat, converting the design to a mechatronic solution has made thermostats more
accurate, easier to use, and they save you money.
