The company's newest single-axis controller/driver, designed for lower-cost network support, has communications options such as RS232, RS465, CAN and Ethernet. It allows CAN-using devices to work at the same time with a supervisory network that uses RS232, RS485 or Ethernet. It works well with the company's NEMA 17 and NEMA 23 frame I-Grade step motor/encoders. It comes with breakouts for power, communications and I/O. Its closed loop control (servo) of a stepmotor offers all the accuracy of a traditional servomotor, with better torque for applications up to 2,000 rpm. It works with only one cable for motor and encoder signals, and functions well on lines up to 50 ft. It comes with 12-48V dc input power, built-in voltage clamp and power resistor, four analog inputs, electronic gearing and camming, SSI encoder interface and many other features.
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.
