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.

Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
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.
