Positioning Assemblies

UniSlide assemblies from Velmex (Bloomfield, NY) deliver movement in one, two, or three dimensions with linear motion. The systems also can be customized for specific requirements. They are compact, and the design allows for construction of multi-axis systems. They are available in an array of standard manual or motor-driven models and sizes, including linear assemblies, elevating tables, and XY tables. They can be customized with rapid/fine motion, thumbscrew locks, special finishes, way covers, revolution counters, position encoders, or other options. The assemblies are constructed of a hard aluminum alloy and PTFE bearings. Linear UniSlides have a maximum load capacity up to 400 pounds horizontally, and 100 pounds vertically. Straight-line accuracy with precision lead screws is 0.0015" per 10" or better of the screw motion. The elevating tables and XY tables can lift up to 100 pounds.

Carolyn Parcheta, NASA Postdoctoral Fellow, Jet Propulsion Laboratory, Pasadena, CA

     A geologist by training, Carolyn Parcheta had an idea in July of 2013 to develop a robot that explores and measures the shape of volcanic fissures. She worked with engineering teams at JPL to develop the VolcanoBot. In May 2014, the robot explored Mauna Ulu on Kilauea’s East Rift Zone in Hawaii. A smaller, more compact version, VolcanoBot 2, will return early this month.

Products of Tomorrow: March 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Smart-Grid-Ready Instrumentation

The term “smart grid” is an umbrella term used to refer to new technologies that aim to address today’s electrical power grid challenges. At a high level, these technologies address challenges associated with grid reliability and reactive maintenance, renewables integration, and disturbance detection. One way to help address these challenges is to push decision-making and intelligence closer to the grid, embedded within flexible instrumentation to achieve faster response times, better bandwidth utilization, and functionality field upgrades that will keep field instruments up-to-date with the latest algorithms and methodologies to monitor and protect the grid.
