While most engineers argue Ethernet TCP/IP is inappropriate for an I/O bus, Gerd Hoppe, President of Beckhoff North America, says his company is going in the opposite direction with its new product RTEthernet—introduced in Europe in November 2002 and just now available here in the U.S. Beckhoff 's software engineers, old hands at tinkering with the Windows operating system, have devised a way to communicate directly with a standard COTS Ethernet controller card using short, 7-microsecond telegrams. One of these tiny telegrams could contain the status of as many as 368 I/O points. Regular TCP messages are held temporarily in a buffer while the telegrams pass through the system. Aptly described as an "onion ring" design, it can encapsulate any fieldbus protocol inside its Ethernet telegrams, giving RTEthernet potential compatibility with dozens of different fieldbus systems.
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.
