While I found the concepts introduced in this article very interesting, I struggled throughout as well. By placing the enineering burden from three major disciplines on one person without the benefit of additional perspectives that come from having a team is not a direction that I would normally pursue. Most folks recognize the value of interacting with their colleagues that specialize in other areas. Whenever I would build a test set, building a test fixture was a very important part of the design. Having very limited mechanical engineering ability, I consulted with the guys that had that expertise...and through our collaboration an effective test fixture design would emerge. I would respectfully disagree with the scenario of a very unintelligent design that did not work well because it was built by three different engineers with differing fields of expertise.
It seems to me that in order to educate a mechatronics engineer would also take an even more intensive education with a much more expanded degree plan - something a lot of folks would not be able to afford time-wise or financially - but if they didn't get a good education they would be a "jack of all trades and master of none" which might do well for home projects but not for industry.
