Test engineers in industries ranging from aerospace and defense to consumer electronics are facing the challenge of testing increasingly complicated designs with shrinking timelines and budgets. To address these issues, engineers and scientists are incorporating new test and measurement technologies that are capable of meeting complex design requirements without raising costs. National Instruments (NI) has identified five trends it anticipates will significantly influence the test and measurement industry over the next three years.”Companies are turning to the latest technologies including PXI, FPGAs and multicore processors to develop high-performance test systems that can meet consumer demand for higher-quality products,” said Eric Starkloff, National Instruments director of test product marketing.

“Fortunately, more technology vendors are developing industry-standard tools capable of solving problems that previously depended on expensive, dedicated test systems.”

ADVANCED Motion Controls announces development efforts with Robosoft, located in Bidart, France, to produce a new standard in service robots. To date, Robosoft has uniquely created a multi-use hardware platform for remote service mobile robotic needs. The robuLAB series for example can be used for indoor security, medical assistance, assisted living or any other service need.

The hardware incorporates ADVANCED Motion Controls servo drives at the heart of the motion control. Robosoft’s robuBOX is a flexible software platform that is operationally ready to take on many tasks and can be quickly and safely tailored to fit the customer’s exact needs. With the combination of the Robosoft’s hardware and software, including ADVANCED Motion Controls DigiFlex Performance high power density servo drives, OEM’s and users can develop new robotic applications much faster than attempting full scale development.

“Motor-drives are the key components in service robotics, this is the gateway between hardware and software,” says Vincent Dupourqué, CEO of ROBOSOFT. “The ADVANCED Motion Controls drives perfectly fit our control software needs, allowing implementation of advanced algorithms for mobile robots and manipulators.”

Additionally, for those customers looking to develop their own control algorithms within Microsoft’s Robotics Development Studio, drivers for ADVANCED Motion Controls’ DigiFlex Performance servo drives, and additional software features, are being developed by Robosoft in the robuBOX and will be available to developers before the end of 2008.

“Flexible mobile robotic platforms with available standards have now come of age. Robosoft’s robuters and robuBOX hardware and software products are proving to be excellent building blocks for companies looking to create their own specific robot designs” says Karl Meier, Marketing Manager of ADVANCED Motion Controls.

About robuBOX
RobuBOX launch took place in mid-2006. Several robots embedding the robuBOX have been deployed since: Estele, the remote tele-echography system already in operation in 4 French Hospitals, robuCAB an automatic vehicle guided by GPS, a mobile robot for construction sites carrying pallets of materials, as well as the off-the-shelf ROBOSOFT robuLAB and robuROC mobile platforms for miscellaneous indoor and outdoor applications.

robuBOX is now available and allows robotics integrators and mass market manufacturers to seamlessly build a variety of advanced robotics solutions using the Microsoft Robotics Studio environment.

Gnat-sized robots, microscopic gyroscopes, television beamed directly onto your retina. This may sound like a grocery list for a crazed sci-fi visionary. But all these projects are in the works today, thanks to an emerging chip technology known as microelectromechanical systems. While magical microbots may still be a few years away, MEMS are already a multibillion-dollar business in the car, printer, and display-projection industries.

Traditional chips are flat, static structures. MEMS, by contrast, are silicon wafers packed with kinetic, three-dimensional gizmos: laboratories, laser-guided mirrors, canals flowing with chemicals. An offshoot of the semiconductor industry, MEMS benefit from the well-known peculiarities of the silicon universe - every year chips get tinier, cheaper, and faster.

The U.S. Air Force Research Laboratory has authorized Raytheon Company to demonstrate target recognition technology designed to increase protection for ground forces without compounding risk to an aircraft stalking enemies who threaten those forces.

First in a laboratory and then aloft, the company expects to show how its Air-to-Ground Radar Imaging II program would permit aircraft at a safe distance to detect, track and target hostile forces in motion on the ground.

The laboratory demonstration is expected in autumn 2008, followed by a flight next spring aboard a Raytheon test aircraft.

Cleveland Botanical Garden and Kent State University’s Liquid Crystal Institute today officially launched a pioneering research project to explore the potential of liquid crystal technology for creating more sustainable, energy-efficient greenhouses.

At an event held on Wade Oval, the Garden and the University unveiled the two greenhouses that will be used in the first phase of the project. One contains liquid crystal panels and the other, a control, has plain glass. A demonstration revealed how the panes “switch” to manage the amount of sunlight that enters the greenhouse.

In industrial applications, a digital-to-analog (D-to-A) interface may be rather straightforward but the analog-to-digital (A-to-D) converter (ADC) can be a challenge. The capacitive input stage of both delta-sigma and successive approximation register (SAR) interfaces used for the ADC requires signal capture within a limited time frame. An improper signal chain can cause ringing and oscillation and result in inaccurate readings. However, this is just one of many factors to consider when selecting an ADC.

Signal Chain

High-performance ADCs convert the output of an analog sensor to a digital format for a microcontroller or digital signal processor. The selection of the ADC must be part of a systems approach. “When somebody starts a design, you start with the sensor, you see what kind of output impedance it has and you choose an amplifier and resistors around the amplifier and you choose that configuration based on your sensor,” says Chuck Sins, applications engineer, National Semiconductor. “Based on the accuracy of your sensor and what you are ultimately trying to achieve, then I choose the resolution of the ADC.”
