Mechanics vs. Electronics

October 26, 2008 by Steve Meyer · Leave a Comment 

I have offered the opinion that mechatronics is a field whose solutions are mechanically bounded.  The limits to performance are initially constrained by the mechanical design of the system.  This is no small matter.

In many companies the mechanical design and electrical design are separate activities.  I know many companies whose mechanical and electrical departments are at war with each other after years of struggles and crises generated by the separation of the disciplines.

Sometimes the mechanical design team takes the lead in creating a machine with longevity as its primary constraint.  And customers deserve equipment that runs reliably for many years.  The mechanical designers may choose heavy materials for high strength to support the demand for strength and reliability.  Read more

Electronic Dive Buddy

October 22, 2008 by admin · Leave a Comment 

An Electronic Dive Buddy built by University of Auckland engineering students could make scuba diving a much safer sport.

Anatoly Kudryashov and Jenny Xu from the Department of Mechanical Engineering’s Mechatronics Engineering specialization have designed a computerized system to automatically adjust a diver’s buoyancy if they get into trouble. The project was supervised by Associate Professor Vojislav Kecman and assisted by Technical Officer Rob Earl.

“The most important task for a diver while underwater is buoyancy control. Normally this is controlled manually by adding or releasing air in a buoyancy control device, which is worn like a jacket,” Anatoly says.

“To rise in the water, a diver adds air to the buoyancy control device. To sink, air is let out. If the buoyancy is not adjusted correctly, a diver may rise too rapidly or descend too quickly to an unsafe depth, risking serious injury or sometimes death,” Jenny says.

The Electronic Dive Buddy attaches to the buoyancy jacket and monitors the diver’s motion while underwater. It automatically adjusts buoyancy if an unsafe depth or velocity is reached. The device also has a ‘cruise control’ feature, allowing divers to automatically maintain a desired depth in the water.

Anatoly, who is in avid diver, couldn’t understand why computer control hadn’t been introduced to scuba diving and decided to tackle the problem as part of his assessment for a Bachelor of Engineering Degree. Mechatronics Engineering students work in pairs to complete a major research project in their final year of study.

The Electronic Dive Buddy prototype was tested in the laboratory and in a 4.7 metre deep swimming pool.

“Our tests so far have proven the device to work, so the next step is to look at its marketability. As far as I know, a device like this does not exist,” Anatoly says.

Anatoly and Jenny presented their findings at The Department of Mechanical Engineering project display day on Friday, 10 October 2008. The students received an IPENZ Award for the quality of their presentation and display.

SKF Solutions for Increased Productivity and Sustainability Benefits

October 22, 2008 by admin · Leave a Comment 

SKF has a wide range of technology that can be applied in the Agriculture Industry to increase productivity, lower operational costs and deliver sustainability benefits.

Solutions are typically aimed at extending machine component service life and reducing maintenance, both of which contribute to less stoppages, more reliability, and more machine availability. All of this results in longer operational hours for tractors, combines and attachments in the agriculture industries. Emphasis is also put on designing solutions with minimal lubrication needs. Where needed, the use of automatic centralized lubrication systems provide accurate and timely lubrication to all key rotating, sliding and oscillating positions on the vehicles and equipment. This reduces the use of lubricants, reduces component wear and reduces ground contamination from oil and grease, thus contributing to environmental care and sustainability. Advanced new mechatronics solutions offer greater productivity through ergonomic benefits while consuming less power than traditional hydraulic systems.


SKF Agri Hub increases productivity with less pollution
The SKF Agri Hub is a completely new product used in rotary discs for land tilling.  SKF field trials indicate an increase in productivity of up to 150% and a reduction of the total cost of ownership by up to 30%. Furthermore it is lubricated and sealed-for-life saving an estimated 500 kg of grease per machine, over 10 years, that could leak from conventional designs. It is reliable for an estimated 10 farming season and is relubrication- and pollution-free and easy to install. The SKF Agri Hub is a single unit, replacing traditionally up to 15 separate components and is expected to reduce OEM costs in management and overhead by up to 90%.

SKF virtually maintenance-free solution for front steering application in a tractor
The SKF self-lubricating axial spherical TX plain bearing and a specially developed seal virtually eliminate the need for maintenance in this steering linkage application. The unit also provides increased load carrying and extended service life.

There is no need for standstills for relubrication and the risk of bearing failures due to improper, or lack of, lubrication is virtually eliminated. It is also environmentally friendly; there is no grease leakage and thus contamination of land is avoided. This solution provides higher reliability and improved productivity.

Operating in temperatures from -20 to +50 degrees Celsius and designed for 300,000 operating cycles in an environment of straw, stones, fertilizers, mud and high pressure water cleaning, the SKF solution outperforms previous designs in this application.

More operator comfort and safety with SKF mechatronics solutions
Global positioning systems (GPS) are widely used in Agriculture Industry, saving time and up to 10% fuel due to no more overlapping by harvesters. Their success is partly due to SKF sensor solutions that are coupled to the GPS.

The SKF sensor solution is in the steering column of the tractor and is coupled to the GPS. It enables the farmer to drive to a starting position and then engage the GPS control for automatic steering while mowing. If the farmer sees obstacles in his path, or needs to turn at the end of the field, he simply turns the steering wheel. This disengages the GPS steering and puts the farmer back in control. When the obstacle is avoided or the turn is made the farmer can re-activate the GPS for the next part of the mowing process.

Continuous variable transmissions (CVT) are used today in many tractors. Although there are many advantage of CVT, especially when mowing, one main issue of this new technology is that the traditional mechanical brake in emergency situations, like mowing downhill, can sometimes be no longer fully effective. This is because if the tractor loses power there is no engine brake possible and the forces involved can be too high for a farmer to apply a hand operated mechanical brake. SKF has developed an electromechanical actuation system that can get power from the battery and provide an effective emergency brake function in all critical conditions for the farmer.

The Sound of Mechatronics

Yamaha’s Disklavier Mark IV piano is more than just ebony and ivory, integrating complex electronic systems and components to take sound where it’s never been before.

By Ralph Raiola,

The task of building a piano capable of producing the sound quality expected and sought after by the world’s best musicians is a difficult enough task. Add modern digital features—built-in recording and playback, data storage, an LCD touchscreen interface, wireless remote control, and more—into the mix, which is what Yamaha has been doing for years with its Disklavier series, and there is always the potential for disaster.

Motion Made Easy - Part 2

October 19, 2008 by Steve Meyer · Leave a Comment 

So to continue the thought process, motion control as a subset of the field of mechatronics is the intersection of mechanical engineering and electrical engineering.  Two very diverse disciplines with totally different areas of concerns and parameters of what is important.

The intersection of the two fields might be a very narrow slice of the engineering disciplines, but in practice it doesn’t work out that way. The electronics domain requires knowlege in control, power device implementation, sophisticated protection schemes, and lately, communications protocols that are increasingly required in factory automation settings.  Mechanical engineers must deal with load, mass, friction, acceleration and all the related enviromental conditions required for a given product to be successful.

In the end, the intellectual examination reveals another interesting lesson.  Experience counts.  A lot.  And it is enigmatic at the same time, because I don’t know how you capture this most human quality of accumulating a variety of seemingly unrelated experiences and being able to integrate them into a meaningful whole.  But there it is.

Experienced motion control people are the industry’s biggest asset.  It takes many times more effort to develop high quality applications or products without experienced people.  The learning curve takes too long.  Many companies re-create that learning curve and miss the window for getting to market with something excellent that moves their us all forward.  Spending too much time or money can wreak havoc with new product introductions and make some products too expensive to be sustainable.

An interesting contradiction is the growing complexity of setup and diagnostic software  for AC drives and starters, when, at the same time servo drive designers are trying to simplify their products for “Ease of Use”.  In principle, all three product domains serve three phase electric motors.  One intelligent starter I recently reviewed had 168 parameters that had to be configured in order for the starter to operate.  AC Drives have had close to 500 parameters.  Why are the servo products migrating to greater simplicity and the other products to greater complexity?  Are we attempting to collect some “added value” by making things complex, and at the same time adding value to other products by making them “easy to use”, i.e. - less complex?

So how do we make the mechatronic design cycle more effective?  Many colleges are offering mechatronic tracks of study in their engineering departments.  Foundations like First Robotics Competition are bringing the challenge to students who have never built a robot before.  These programs bring young minds together with more experienced people and offers a means of transferring a great wealth of knowledge to a new group of people who will advance the field in just a few years.

But is “Motion Made Easy” contradictory to the natural complexity of the field?  The connection is Experience.  Experience is what makes the hard stuff easy and the really impossible stuff do-able.  So again I will say, if you haven’t done motion control projects before, be cautious, it may not be as easy as you think.  And check around for someone with more experience with solving the problem you are after.  You might find that the “better, cheaper, faster” solution is possible, with a little help from a qualified expert.

Megatronics’ Inevitability

October 17, 2008 by admin · Leave a Comment 

By Richard Comerford,

Electronic Products

In the beginning of September, a press release came to my e-mail inbox that really caught my attention. Considering the facts that (1) I get hundreds of e-mails every day, (2) most are about a “new product that is the [first, smallest, fastest, least expensive, most powerful] of its kind”, and (3) I’ve been in the tech journalism business since Ben Franklin started flying kites, it takes something pretty unusual to stop me in my tracks.

The release was from a company called Vector Fields, a part of Cobham plc based in Aurora, IL, and it was announcing the release of design tools to help RF designers exploit the properties of metamaterials. The tools are part of its work for the Advanced Materials for Ubiquitous

Leading-edge Electromagnetic Technologies (AMULET) research project, which is a three-year £3.4m collaborative R&D project funded in part by the UK’s Technology Strategy Board. The project is led by a consortium consisting of Vector Fields, Cobham’s ERA Technology, the National Physical Laboratory, and Queen Mary University of London.

Metamaterials are a fairly recent class of engineered materials that were first conceived at the end of the last millennium by Rodger M. Walser of the University of Texas at Austin. He defined metamaterials as: “Macroscopic composites having a manmade, three-dimensional, periodic cellular architecture designed to produce an optimized combination, not available in nature, of two or more responses to specific excitation.” Recently, there has been theoretical discussions about developing cloaking materials that can bend light around objects to make them invisible.

Obviously, such materials could have a significant impact on warfare and armaments, and so the U.S. Defense Advanced Research Projects Agency has been funding development since 2001. DARPA says it has completed this project, but given the nature of the agency’s activities, details are hard to come by.

Getting back to AMULET, Vector Fields’ role in program is to provide antenna developers with enhanced design tools to simulate metamaterial structures. The first phase of this support is currently being released to the market in the new version of the high-frequency electromagnetic design tool, Concerto. One of the key problems addressed by this software, according to it’s developers, is the need for efficient and fast simulation. Concerto handles this by exploiting the periodic nature of passive metamaterial structures to minimize the computations required. The AMULET project will also be exploring the use of active metamaterials, and Vector Fields intends to add modeling support for these in future developments.

There were several things about the announcement that made me take note. First of all, this was about the practical application of metamaterial to engineering problems not of a military nature, but of key commercial importance to everyone involved with wireless technology. Further, the tools are not just for a few researchers working on stealth projects, but for anyone who would like to get involved with this game-changing technology.

And there is no doubt that metamaterials are game changing. The properties of metamaterials are directly dependent on both their physical parameters and their electrical characteristics, and designs based on such materials must take both physical and electrical properties into account simultaneously if it is to be done at a practical pace. The fact that tools are being developed as part of the AMULET project is a clear indication that traditional approaches will not succeed with this
new technology.

If these new materials and tools create the revolution in design that I believe they will, it will certainly mean that we cannot go forward without mechatronics. It will become impossible to create a competitive product without simultaneously engineering its mechanical, physical, and electrical attributes. What’s particularly encouraging is the fact that those working in the field seem to realize that tools must come first, so as to allow designers to completely explore possibilities quickly and thoroughly, and thereby avoid most of the trial and error approach which has hampered development in the past.

Modular programming and articulating arm kits let you design your own robotic-based packaging system.

By Tom Jensen
Engineering Manager
ELAU Inc., a Company of Schneider Electric

For many years two factors gave robot designers and manufacturers a lock on developing equipment for the packaging market: patents and the specialized kinematic knowledge required to program robotic motion. While the robotic arms were under patent, the controls held the unique motion algorithms needed to handle the complex path planning, blending, and resolution of multiple trajectories to the same point. Thus, robot articulating arms and specific controls were exclusive to robot developers.
