NASA Robot Explores Volcanoes

Carolyn Parcheta, a NASA postdoctoral fellow based at NASA's Jet Propulsion Laboratory in Pasadena, California, and JPL robotics researcher Aaron Parness are developing robots that can explore volcanic fissures."We don't know exactly how volcanoes erupt. We have models but they are all very, very simplified. This project aims to help make those models more realistic," Parcheta said.Parcheta, Parness, and JPL co-advisor Karl Mitchell first explored this idea last year using a two-wheeled robot they call VolcanoBot 1, with a length of 12 inches (30 centimeters) and 6.7-inch (17-centimeter) wheels.VolcanoBot 2, smaller and lighter than its predecessor, will explore Hawaii's Kilauea volcano in March 2015. Parcheta's research endeavors were recently honored in National Geographic’s Expedition Granted campaign.

Coming Soon - How to Select the Right Adhesive for Aerospace Applications

The selection process of an adhesive, coating, or potting compound can pose a few challenges for engineers. Some of these include adhesion, temperature and thermal cycling resistance, and handling and curing time. For certain aerospace applications, compounds may need to pass NASA low outgassing specification ASTM E595 or UL 94V-0 for flame retardancy, for example.

New Vision Algorithm Enables Household Robots

Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory believe that household robots should take advantage of their mobility and their relatively static environments to make object recognition easier, by imaging objects from multiple perspectives before making judgments about their identity.Matching up the objects depicted in the different images, however, poses its own computational challenges.In a paper appearing in a forthcoming issue of the International Journal of Robotics Research, the MIT researchers show that a system using an off-the-shelf algorithm to aggregate different perspectives can recognize four times as many objects as one that uses a single perspective, while reducing the number of misidentifications.The team's new algorithm is 10 times as fast, making it much more practical for real-time deployment with household robots.SourceAlso: See other Software tech briefs.
