Precision Torque Feedback for Robotic Arms and Co-Robots
Versatile and adaptive robotic armatures have the benefit of increasing manufacturing productivity by automating and performing complex, repetitive tasks 24/7. Designed to obey commands or to work in unison as cooperative robots (cobot/co-robot), these robots greatly simplify the design of automation systems. To further improve performance, reaction torque sensors are placed in-line with the drive motors inside each joint, allowing development of closed loop control laws to ensure smooth, repeatable, and efficient arm motion.

Can infrared links simplify data center communications?
Data centers are the central point of many, if not most, information systems today, but the masses of wires interconnecting the servers can resemble last year's tangled Christmas-tree lights disaster. Now a team of engineers is proposing to eliminate most of the wires and substitute infrared free-space optics for communications.

Precision dispensing for micro-electronic engineering

The spread of miniaturization in automation has led to an ever-increasing demand for optimum dispensing of the tiniest volumes. Whether in electronics or micro-mechanical engineering, solder pastes, adhesives, lubricants and sealing compounds must be applied precisely where needed, in exactly the right dosage, and without spillage or dripping. Compact, high-torque micro DC motors can deliver the precision and small size needed for such a challenge.

How to choose the right relay

Relays come in a variety of form factors, styles, and technologies. Depending on your application, only one relay type may be suitable. In other cases, multiple relay types may be appropriate. By understanding the strengths and weaknesses of the different relays, you should be able to pick the one that is best suited for the job at hand. National Instruments lays out the options.

Carbon composite bellows springs for lightweighting and more
The Carbon Composite Bellows Spring (CCBS) from MW Industries is a system of carbon fiber elements that combine to work as a high-performance, lightweight, and design-flexible compression spring meant to replace conventional coil springs or metallic Belleville disc springs. It offers value through unique dynamic characteristics and unparalleled in-the-field design flexibility. A functional spring is made from several individual elements, paired in sets and joined to make a stack. The spring rate of the stack is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Applications include motorsports, aerospace, outdoor recreation, general industry, and high-performance activities.

Highest-accuracy load pin delivers amazing performance
The tecsis Model XLPD Force Sensing Load Pin features a patent-pending design that achieves superior accuracy up to 0.25%. Most of the accuracy error in a load pin is the result of variations in the application of the load. Now, tecsis engineers have found a way to virtually eliminate loading-induced error and create the most accurate and repeatable load pin on the market. The XLPD is available in ranges up to 16 tons (0-150 kN) and delivers a combined +/-0.25% linearity and hysteresis, and repeatability of ±0.1% FS. Standard output is 2 mV/V with an excitation of 10 Vdc. This unit is IP67 rated and built to perform with all stainless-steel construction to a 150% safe overload rating. Created originally for harbor cranes and mobile and stationary straddle cranes, these force-sensing load pins have set a new standard for weighing applications of all kinds.

Jet engines that run hotter: Scientists find new way to remove defects from heat-resistant alloys
Researchers at the Ohio State University have made a discovery in materials science that sounds like something from the old Saturday morning cartoon “Super Friends.” They’ve found a way to deactivate “nano twins” to improve the high-temperature properties of superalloys that are used in jet engines. The advance could speed the development of powerful and environmentally friendly turbine engines of all sorts.

Disney engineers tackle wireless power transfer
Wireless power delivery has the potential to seamlessly power our electrical devices as easily as data is transmitted through the air. Existing solutions, however, are limited to near-contact distances and don't provide the geometric freedom to enable automatic and un-aided charging. Disney engineers introduce quasistatic cavity resonance (QSCR), which can enable purpose-built structures, such as cabinets, rooms, and warehouses, to generate quasistatic magnetic fields to safely deliver kilowatts of power to mobile receivers contained nearly anywhere within. Although we all probably won't live in aluminum-clad rooms, the potential is here for a real next-gen breakthrough.
