Size really does matter when it comes to direct-drive linear actuators. The smaller the actuator, the more that can be crammed side-by-side into the tight spots normally occupied by pneumatic cylinders or ball screws. But size isn't everything. Force and acceleration capabilities matter too. So does ease-of-installation. Copley Controls has just developed a compact actuator that balances all of these needs. Sized to mount on 28-mm centers, the new ServoTube Model STA11 is the company's most compact direct-drive linear actuator to date. Yet it's no weakling. The STA11, which has an 11-mm thrust rod, offers a peak force of 92N and continuous force of 23.5N. It has maximum velocity of 5.6 m/sec, accelerates instrumentation-type loads to 25g, and provides a 14- to 232-mm stroke. Read more about the new actuator here, including comments from one of the first engineers to use it.
Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
Plant user interfaces are beginning to incorporate the consumer features such as swipe, double tap, and pinch. The driver is Millennials who expect plant equipment to match the sophistication of the smartphone.
