Service Robots Use Flat Motors to Provide Reliable, Safe Motion

Unlike industrial robots for manufacturing, service robots come with their own specification requirements aimed specifically at the end user, and the most discriminating user at that — a human being. That’s why designing and manufacturing service robots takes a particular set of skills and engineering expertise.

Encoders Ensure Position Accuracy of Linear-Torsion Tester

Instron (Norwood, MA) manufactures materials testing equipment and accessories that are used to test samples ranging from components for jet engines to medical syringes. The company’s ElectroPuls systems are used for fatigue testing, which examines the behavior of materials under fluctuating or cyclic loads in the elastic regime. The E1000, E3000, and E10000 fatigue test systems are suited for biomedical/biomechanical research applications, and feature a wide dynamic performance range and low force characteristics. The all-electric systems use linear motor technology to eliminate the need for ball/lead-screws, and enable slow-speed static tests through to high-frequency dynamic tests at over 100 Hz.

Kenneth O’Connor, Coatings Engineer, Goddard Space Flight Center, Greenbelt, MD

Kenneth O’Connor has worked with NASA Goddard engineers to develop a nanotextured coating with hydrophobic properties. The technology minimizes dust, liquid, and ice accumulation on its surface, similar to a leaf on the lotus plant. See below for details on a live webinar this month.

Wireless Occupancy Sensors

Dialight (Farmingdale, NJ) has unveiled its new wireless occupancy sensor, a battery-powered plug-and-play sensor designed to integrate seamlessly with any Dialight smart lighting system. Using Pyroelectric InfraRed (PIR) technology, each sensor can instantly switch a single light or a group of lights from off to on or from a dimmed state to on when motion is detected for full visibility and brightness only when needed. Each low-profile sensor is just under 2 ½ inches in height and 5 inches in diameter, weighs only 10 oz. and has an operating range of -40°F to +149°F.

Networked Lighting Controls

Hubbell Building Automation (Austin, TX) NXTM networked lighting controls now have added daylighting capability. The NXDS daylight sensor auto-configures with the NX Room Controller. The NXDS daylight sensor is designed for open loop operation, measuring natural light coming in through a window. It communicates with the recently-launched NXRC series Room Controller, which directs switching or dimming of the lighting. The NX system advantage includes controlling multiple zones of lighting within a space. The devices connect via standard CAT5 cables. Both indoor and outdoor versions of the NXDS sensor are available.

LED Driver

Innovations in Optics, Inc. (Woburn, MA) has introduced the Model 5000A-100 LED Driver/Controller for powering its patented and patent-pending High Power LED Light Engines. The 5000A-100 LED Driver provides constant current in continuous, pulsed or pulsed width modulation (PWM) modes. An embedded system adds network control with 10/100Mbps Ethernet connectivity. The Model 5000A- 100 is intended for OEM applications. Drive current in continuous mode is selectable from 7.5 to 75A at 0.6 to 5.5VDC output. The output current setting is adjustable either locally or remotely from 100% down to 10% using analog adjustment and as low as 1% with PWM.

Intelligent Lighting System

The BrainLight series by EVT (Karlsruhe, Germany) is an intelligent lighting system that allows the user to control both color and brightness, as well as create and save individual lighting patterns. At present the BrainLight series consists of a back light (BrainLight QC) and a ring light (BrainLight R). The back light has separately controllable rows of red, green, blue and white LEDs. There is a diffuser glass in front so the light spreads evenly over the object. All in all there are 48 LEDs, arranged in a grid. The size is 30 x 40 mm, but extra rows of LEDs can be added. The ring light has a RS232 or TTL UART interface and a +5V or 12-24V input voltage. The LEDs are separated into 8 segments each with 3 LEDs.
