I agree. The RJ45 physical connection standard is a definite weak link. Surprised someone hasn't worked out a solution, yet. Other than that Ethernet is really good at data transfer, but I still think it's iffy for real time control.
Ethernet protocols have developed and gotten to the point of near domination in plant networking including high performance motion control, and there really is not a lot of competition. Device networks is still an area in the factory where there are options like CANopen, etc.
Al, this is another example I have seen in Design News of Ethernet being used in the industrial world. It is interesting to see how widespread ethernet's adoption has been. I worked with the very earliest implementations. Ethernet won the battle in the computer connectivity world because of its flexibility. It has been taking over the large scale telecom carrier world. Now, it seems to be making significant inroads in the industrial networking world. Not bad for an open standard.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
