NASA's Game-Changing Robotics

“Over the years, I’ve asked people, ‘If you had a robot, what would you want it to do for you?’” said Rob Ambrose, principal investigator for NASA’s Game Changing Development Program and chief of the Software, Robotics, and Simulation Division at NASA’s Johnson Space Center. When he asks astronauts, they usually tell him they want the robot to do chores.

Machined Parts Accelerate Design Tests for NASA

Machined aluminum parts and glass-filled nylon parts made with selective laser sintering Proto Labs, Inc. Maple Plain, MN 877-479-3680www.protolabs.com University student Mel Du was searching for a source to manufacture metal parts for a student research challenge project he was working on for NASA. The project centered on designing, building, and testing an asteroid-sample retrieval and containment device for a simulated space mission. As part of the development stage, the team at San Antonio, TX-based Trinity University produced several prototypes on the school’s in-house, production-model, fused deposition modeling (FDM) 3D printer.

Editor’s Choice: July 2016

A device for nondestructive testing of hermetic seals of containers or instrumentation can detect both large and small leaks, as well as the relative leak rate. Its simple design eliminates the need for expensive instrumentation such as a mass spectrometer to analyze leaks and achieve high sensitivity. Low in cost and simple to manufacture, the device has uses in industries from aerospace and automotive, to semiconductors and optical devices, to food and pharmaceutical packaging. Find out more on HERE.

Walk and Roll Robot

A CAD model of the Walk and Roll Robot. To traverse smooth terrain, the most efficient motion is rolling; however, when a wheeled vehicle encounters obstacles, it has to avoid them, if possible, or choose an alternate path. Legged vehicles can traverse these obstacles by stepping over them, but are not energy-efficient on smooth terrain. The Walk and Roll Robot, developed at NASA’s Goddard Space Flight Center, combines walking and rolling for energy- efficient motions. The robot has a compact design in which all of the components are contained within the body, allowing it to be used for applications in harsh environments where robots traditionally have difficulty with debris, moisture, or dust. Other applications include urban search and rescue missions, and military reconnaissance and exploration. Visit http://technology.nasa.gov/patent/TB2016/GSC-TOPS-43

Testing a Robotic Miner

Resource Prospector sits in the vacuum chamber that simulates the thermal environment and low atmospheric pressure and density the rover will experience on the Moon. The Resource Prospector (RP) rover could be the first robot to mine for resources on another world. Targeted for launch in the early 2020s, RP will search for and characterize sub-surface water, hydrogen, and other volatiles on the Moon. But first, NASA needs to test its resilience to the harsh environments of deep space and extremely cold temperatures on the Moon. During testing in a thermal vacuum chamber at Johnson Space Center, NASA simulated the thermal environment and extremely low atmospheric pressure and density that RP would experience. Learn more about Resource Prospector in the feature article HERE.

Extreme Low Frequency Acoustic Measurement System

This system detects and locates atmospheric clear air turbulence and severe weather. Langley Research Center, Hampton, Virginia NASA’s Langley Research Center has developed a system to detect and locate atmospheric clear air turbulence (CAT) by means of a ground-based infrasonic array to serve as an early warning system for aircraft. This system could augment existing systems such as pilot reports (PIREPs), airborne lidar, and airborne radar. The NASA system offers a benefit since the existing electromagnetic methods lack targets at 30,000-40,000 feet and will not detect CAT. Because CAT and severe storms emit infrasound that propagates over vast distances through the Earth’s atmosphere, the Langley system offers an excellent early warning opportunity. The system has been able to detect known events — such as detection of the launch of the Space Shuttle in Florida all the way from Virginia. It also has correlated data with NOAA’s PIREPs information.
