New servos verus no servos

NO RATINGS
Until servo systems became more reliable, more powerful, and less expensive, they simply were not as good a choice, and they were seldom cost effective. Some machines did use a lot of shafts, gears, and chain drives, but that was often because there was no other way available to keep a bunch of motions in the proper relationship. HYdraulics were often used because there was no other economical way to provide that much foce in that small a volume. 

So really, don't fault the older mechanisms, since there was not much choice.

The modern servo controllers are providing control options that did not exist before, and at power levels that were simply not available. So we do see that the new generation of servo systems does offer a way to do things thatwas not available previously. The older technologies were not a poor choice, they were the only choice. 

But the new networked servo systems, while providing a lot of benefits are also bringing along a few challenges. Systems that previously were locked into the correct sequence of motions are now able to be accidently programmed to crash and destroy themselves, and in a hurry, as well. So now the motion programmer must pay far greater attention to a lot more details, and the same goes for any who would attempt to make small changes to the programs. So there are some very real and quite serious concerns when changing from mechanical systems to interlinked servo systems.

Nice round-up

Nice round-up of the technologies that are modernizing factories, making them safer, more efficient and generally more productive. I would add robotics to the list as well, especially with efforts like Rethink Robots' Baxter (http://www.designnews.com/author.asp?section_id=1386&doc_id=263186) and more autonomous and safer robotics coming into play. Perhaps it's a little early for mass adoption but I think it will eventually trend in that direction.

Latest Analysis
Lithium-ion battery prices will drop rapidly over the next 10 years, setting the stage for plug-in vehicles to reach 5%-10% of total automotive sales by the mid- to late-2020s, according to a new study.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
The big picture to this hands-on technology curriculum is to illustrate to students that the future of IoT and IoE (Internet of Everything) development can be created in today’s classroom.
A recent Design News-exclusive study proves that engineering professionals are at the very forefront of this push into the future and making direct financial, performance, and value impact on their organizations by being personally involved or final decision-makers on automation solution and component choices.
