MechatronicsThe term mechatronics is used to
denote a rapidly developing, interdisciplinary field of engineering dealing with the design of products whose function relies on the integration of mechanical and electronic components coordinated by a control architecture.
The word mechatronics was coined in Japan in the late 1960s, spread through Europe, and is now commonly used in the United States.
What are the primary disciplines important in the design of mechatronic systems…?
What are the primary disciplines important in the design of mechatronic systems…?◦Mechanics, ◦Electronics, ◦Controls, and◦Computer engineering.
Expectations from a mechatronicsystem engineerHe must be able to
◦design and select ◦analog and digital circuits,◦microprocessor-based components,
◦mechanical devices, ◦sensors and actuators, and◦controls so that the final product achieves a desired goal.
The qualities of mechatronic system designerHe/she must be a generalist, Willing to seek and apply
knowledge from a broad range of sources.
Examples of mechatronic systemsAn aircraft flight control and navigation
system. Automobile air bag safety system and
antilock brake systems.Automated manufacturing equipment
such as robots. Numerically controlled (NC) machine
tools.smart kitchen home appliances such as
bread machines and clothes washing machines, and even toys.
Mechatronic system components
Inkjet printer components
Measurement SystemsThe transducer is a sensing device that
converts a physical input into an output, usually a voltage.
The signal processor performs filtering, amplification, or other signal conditioning on the transducer output. ◦ The term sensor is often used to refer to the
transducer or to the combination of transducer and signal processor.
Finally, the recorder is an instrument, a computer, a hard-copy device, or simply a display that maintains the sensor data for online monitoring or subsequent processing.
