Harvard's Robobee learning to fly:
Harvard researchers are developing a feedback controller that should allow the Robobee to ...
Harvard researchers are getting closer to their goal of developing a controllable micro air vehicle called the Robobee. The tiny robot was already capable of taking off under its own power, but until now it was completely out of control. By adding two control actuators beneath its wings, the robot can be programmed to pitch and roll... Continue Reading Harvard's Robobee learning to fly

El JEMAD desgrana en el Congreso el impacto de los presupuestos de Defensa sobre el Ejército, la Armada y el Ejército del Aire

El JEMAD desgrana en el Congreso el impacto de los presupuestos de Defensa sobre el Ejército, la Armada y el Ejército del Aire:

“El Ejército de Tierra el próximo ejercicio contará con 2,3 millardos, lo que supone una minoración porcentual del 8,16% en relación con el ejercicio actual. El capítulo 1 sufre una reducción de 5,29%, el 2 de 14,58% y el 6 del 25,99%. Estas reducciones se suman a las que se han recibido anteriormente y representan para el Ejército de Tierra dificultades financieras, que se traducen en la dificultad para renovar el material obsoleto o en mal estado y satisfacer necesidades de vida y funcionamiento de las unidades.

Pentagon’s Plans For 3-D Printers: Mobile Labs, Bomb Sniffers and Prototype Limbs

The 3-D printer craze has taken off with everyone from hobbyists and amateur gunsmiths to giant corporations. Less known is how the U.S. military has caught the desktop manufacturing bug too, and is designing printable components for bomb detectors and prototype limbs. Even more radical: The Army has even gone so far to deploy a helicopter-borne 3D-printing laboratory to Afghanistan.

New engine-making tool should result in more fuel-efficient cars

New engine-making tool should result in more fuel-efficient cars:
Fraunhofer's cylinder bore hole honing tool
You may think that the pistons in your car’s engine slide in and out of the cylinder bore holes smooth as silk, but according to researchers from Germany’s Fraunhofer Institute for Machine Tools and Forming Technology, the process could be smoother. If it was, your car would burn less gasoline, and require less oil for lubrication. Well, those researchers have developed an engine-building tool, designed to minimize engine cylinder friction...
