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.

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.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
