Fluid-Filled Frequency-Tunable Mass Damper
Innovators at Marshall Space Flight Center developed the fluid-filled Frequency-Tunable Mass Damper (FTMD) technology that allows for significant distribution of loads while also providing a simple mechanism that allows for the capability to change its frequency of mitigation with negligible impact on the...
Briefs: Imaging
Supersonic flight over land is generally prohibited because sonic booms created by shockwaves disturb people on the ground and can damage property. Armstrong innovators are working to solve...

Lateral Kevlar Suspension Device (LKSD)
The Lateral Kevlar Suspension Device (LKSD) is made up of a support ring that has three spring-loaded tension assemblies equally spaced around the support ring. Connected to these tension assemblies is a band that supports a separate ring capable of holding a cylindrical shaped load.
Briefs: Motion Control
A set of five tiny fundamental parts can be assembled into a wide variety of functional devices including a tiny “walking” motor that can move back and forth across a surface or...

Neural Lander Uses AI to Land Drones Smoothly
Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are often...
Briefs: Motion Control
A smartphone app was developed that allows a user to easily program any robot to perform a mundane activity such as picking up parts from one area and delivering them to another. The app, called VRa, uses...
