Agripper system for automatically handling tiny components, developed in the context of a Eureka project, uses the adhesive properties of ice to pick them up. The gripper first sprays a drop of water onto the object to be handled. It then closes in on the object. As soon as they touch, it freezes the water. The component can then be picked up and manipulated as necessary using the gripping strength of ice. This is around 1N/sq mm which is 20-100 times stronger than that obtained with vacuum grippers, says Mario El-Khoury, manager, industrial control at CSEM, the Swiss Centre for Electronics and Microtechnology, a partner in the European project. To release the object, the tip of the gripper is simply warmed up to the phase- change temperature of the liquid interface. The prototype version of Microgrip is capable of handling components measuring between 0.1 and 5 mm, with an accuracy of 1 micron, at a rate of 1,000 cycles per hour. The "ice" gripper is now undergoing industrialization by AP Technologies and Sysmelec, two other participants in the project. Meanwhile, El-Khoury's group is developing applications for the "ice" technology. A new Eureka project, in which Siemens and Philips are participants, will use Microgrip to manipulate micro-sized parts during low-distortion welding operations.

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.
