About Us

Welcome to the first issue of Mechatronics Designer.

So what exactly is Mechatronics - you ask? That's a good question!

According to Histand and Aliciatore(1):

The word mechatronics was coined in Japan in the late sixties, spread through Europe and is growing in use in the United States.

The term mechatronics is used to denote a rapidly developing, interdisciplinary field of engineering that deals with the design of products whose function relies in the synergistic integration of mechanical, electrical, and electronic components connected by a control architecture.

Well, that's the academic definition. I believe a simpler definition of mechatronics is any intelligent electro-mechanical device which interacts with the physical environment.

In today's world of the ubiquitous microprocessor, mechatronics includes just about everything from 'smart' toasters to Mars rovers! As my wife puts it, mechatronic design is the engineering discipline which attracts engineers who don't know what they want to be when they grow up!

Well said, but also means that we mechatronics designers never leave school ... the challenge for the mechatronics designer is keep up with all of the new technologies, from software to hardware, sensors to CPUs, motors to op-amps and everything in between... It is a field that is both fun and frustrating at the same time.

The Mechatronics Designer newsletter is our attempt to help fill in some of the gaps. Of course we will cover our own our latest product development, but also cover the industry news and events shaping our own design plans and efforts

We are a hands-on company dedicated to serving the design community. Our MechaBlox product family is designed to help designers flatten learning curves and get up to speed fast in different technological application areas. Hand-in hand with those objectives, we believe that education itself is a primary objective. So each issue will include Fundamentally So..., a review of engineering fundamentals for designers just beginning their careers (and us old timers who just pain forgot!). as well real world application Design Files for the seasoned practitioner.

We will also cover some topics that may not appear at first glance to be “mechatronic” in nature - such as PERL-CGI programming, HTML etc... But, with the advent of the pervasive Internet and Machine-to-Machine (M2M) programming, these topics have to be at or at least near the top of a designer's “must at least understand” list!

Finally, we will include book reviews of tech books we actually read, and found to both valuable and of interest to us and other mechatronics designers.

Let us know what you think. If you have any suggestions for topics or improvements, reader's feedback is always appreciated.

Enjoy!

The MB3001 Unipolar Stepper Controller.

Based upon Allegro Microsystem's SLA7030 Unipolar Stepper Motor Controller Chip, the MB3001 MechaBlox card is Small in size (70mmx70mm), but big in performance.

The MB3001 is capable of delivering programmable drive currents in excess of 1 Amp per phase, and because it uses Pulse Width Modulation drive, it get's the extra performance you need out of your stepper motor without the inefficiency and excess heat of bulky RL drives.

Switch Sensor Interfacing.

The simplest digital sensor is a two state, on-off or yes-no mechanical switch. It is cheap and easy to use, but caution! The the impact of it's mechanical properties on system performance need to be considered carefully.

Ohm's Law

George Simon Ohm, was born March16,1789 in Erlangen, Bavaria, Germany.

Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance.

Robert Pease: Troubleshooting Analog Circuits.

Even the most hardened digital designer is gonna have to face an analog interface design or debug session at sometime in his or her career. When that happens, you will want to have this reference handy.

Like Bob Pease, this book has been around for “a while.” But, also like Bob Pease, there is no ready replacement!
