One-part epoxy changes from red to clear under UV

Master Bond UV15RCL is a low-viscosity, cationic-type UV-curing system with a special color-changing feature. The red material changes to clear once exposed to UV light, indicating that there is UV light access across the adhesive material. Although this change in color from red to clear does not indicate a full cure, it does confirm that the UV light has reached the polymer. This epoxy is an excellent electrical insulator. UV15RCL adheres well to metals, glass, ceramics, and many plastics, including acrylics and polycarbonates.

SPIROL Press-N-Lok™ Pin for plastic housings

The Press-N-Lok™ Pin was designed to permanently retain two plastic components to each other. As the pin is inserted, the plastic backfills into the area around the two opposing barbs, resulting in maximum retention. Assembly time is quicker, and it requires lower assembly equipment costs compared to screws and adhesives -- just Press-N-Lok™!

Load fasteners with integrated RFID

A crane, rope, or chain may be required when something needs lifting -- plus anchoring points on the load. JW Winco offers a wide range of solutions to fasten the load securely, including: lifting eye bolts and rings (with or without rotation), eye rings with ball bearings, threaded lifting pins, shackles, lifting points for welding, and more. Some, such as the GN 581 Safety Swivel Lifting Eye Bolts, even have integrated RFID tags to clearly identify specific lifting points during wear and safety inspections and manage them digitally and without system interruption.

Couplings solve misalignments more precisely with targeted center designs

ALS Couplings from Miki Pulley feature a simplistic, three-piece construction and are available in three different types for more precisely handling parallel, angular, or axial misalignment applications. The key feature of this coupling design is its center element. Each of the three models has a center member that has a unique and durable material and shape. Also called a "spider," the center is designed to address and resolve the type of misalignment targeted. Ideal for unidirectional continuous movement or rapid bidirectional motion.

What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

Carnegie Mellon lunar rover wows XPRIZE judges, wins milestone prize

By Byron Spice, Carnegie Mellon University

The Google Lunar XPRIZE announced Dec. 16, 2014, that Andy, a four-wheeled lunar rover designed and built by Carnegie Mellon University, is the winner of a Milestone Prize for mobility after judges concluded it is thus far the only robot among the competing teams to meet development benchmarks for flight readiness.

Other teams continue to contend for Milestone Prizes, which will be awarded Jan. 26, 2015, in San Francisco, but the CMU team is the first and only team to meet the Milestone mobility objectives thus far, XPRIZE said. Likewise, CMU's partner, Pittsburgh's Astrobotic Technology, is the first winner of a Milestone Prize in the imaging subsystem category.

"Andy has proven to be a tough, smart, sure-footed machine," said William "Red" Whittaker, professor of robotics, who led a team of about 50 students, faculty, and staff members from across the CMU campus to create the rover. "We've shaken it to simulate launch forces, driven it through moon dirt, and exposed it to the extremes of lunar temperatures among many, many tests. Our team and our machine faced a rigorous evaluation by world-class judges and came out on top."

The Mobility Milestone Prize includes a $500,000 cash award.

"We don't do anything just for a prize," Whittaker added, "but when a check like this comes our way, we cash it." The prize money will be used to continue Andy's development.

The robot can scramble around giant moon pits, explore lunar caves, or seek polar ice.

Carnegie Mellon is building the rover as it works in partnership with Astrobotic Technology to win the $20 million-plus Google Lunar XPRIZE by landing and operating a robot on the moon. Astrobotic, a CMU spinoff, is developing commercial hardware and services to support space exploration. In addition to the imaging technology for which it won a Milestone Prize, Astrobotic also is developing the Griffin landing craft that will deliver Andy to the moon.

The Milestone Prizes created by Google and the XPRIZE Foundation included three categories: landing system, mobility subsystems, and imaging subsystems. Astrobotic is continuing to pursue the Milestone Prize for landing systems. Other teams still in the running for Milestone Prizes include Hakuto (Japan), Team Indus (India), Moon Express (U.S.), and Part-Time Scientists (Germany).

XPRIZE officials also announced that they have extended the deadline for the competition until Dec. 31, 2016. At least one team must provide documentation of a scheduled launch by Dec. 31, 2015, for all of the teams to move forward in the competition, the officials said.

"We feel confident that we can land on the moon in 2016 and show that a private company can set the course for future lunar exploration," said John Thornton, Astrobotic's CEO.

To receive the mobility prize, the CMU team had to demonstrate that Andy could survive the vacuum, high radiation, and extreme cold of the moon. The team also had to show that the robot could complete -- and could prove that it completed -- a 500-m traverse on the lunar surface, one of the conditions for winning the Google Lunar XPRIZE.

Andy's prize-winning features include:

  • A wide stance, low center of gravity, and high belly clearance combine for unprecedented stability, slope climbing, and straddling of rocks.
  • A soft footprint -- weighing less than 10 lb on the moon -- and wide wheels give Andy superior mobility, while a novel suspension provides strong pulling power.
  • A new method for combining landing imagery with 3D path reconstruction data to plan and document Andy's exploration route.
  • Innovative software that, combined with redundant electronic components, achieves high reliability of electronic systems despite the moon's high radiation levels.

Andy, which derives its moniker from university namesakes Andrew Carnegie and Andrew Mellon, was developed with technical expertise and resources contributed from across the university, including the School of Computer Science, the College of Engineering, the College of Fine Arts, and the Mellon College of Science.

Whittaker said many team members contributed long hours to the creation of Andy. Notable among them were Jon Anderson and Curtis Boirum, both master's degree students in robotics; Joe Bartels, Nate Otten, and Heather Jones, Ph.D. students in robotics; Luke Metro, a sophomore electrical and computer engineering major; John Mann, a junior computer science major; and Jay Jasper, a master's degree student in mechanical engineering.
