Robotic eyes can only see so much—some sensors don't operate well in low light, and sonor systems can be confused by polished surfaces. But thanks to a mechanical engineering student, robots that are sent into dangerous locations may soon be able to scurry in the dark like roaches. Owen Y. Loh of Johns Hopkins University has built a man-made antenna that is made of cast urethane and six strain gage sensors that change resistance as they are bent. Like a cockroach's appendage, the antenna sends signals to the robot's controller, enabling it to sense its position relative to the obstacles and maneuver around them.

On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
