By the Lake, a Flying-Fish Robot Takes Off

A lake is usually a picture of serenity, perhaps the last place you’d expect to find a flying-fish robot launching itself 85 feet in the air.

Microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body have been developed that also can treat tumors in the...

We interviewed an industry expert about the role of inductive position sensors in the IIoT.

Inductive Power Transfer for Spaceflight Systems

NASA Goddard Space Flight Center has developed technology that uses inductive power transfer (IPT) for wireless power interfaces between spaceflight elements (such as the payload, vehicle, and pad). Current spaceflight systems require traditional hardwire connections for power interfaces. This...

The Moon is a treasure chest of science. The lunar samples returned during the Apollo program dramatically changed our view of the solar system, yet they just scratch the...

Employing fluid power to achieve mechanical motion can be implemented via hydraulics using uncompressible liquids or via pneumatics using compressible gasses; typically, air. The latter provides several...

Double-Fed Induction Linear Alternator

This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...

AUVSI XPONENTIAL 2019: Helicopter Drones
Three new unmanned helicopters were unveiled at AUVSI’s XPONENTIAL show in Chicago.
As always, the Air Force Research Laboratory had a huge presence at AUVSI’s XPONENTIAL show in Chicago.
You think riding your Harley Davidson is exciting? Try the ElectraFly.

Mechanical systems such as engines and motors rely on two principal types of motions of stiff components: linear motion, which involves an object moving from one point to another in a straight...

Making electric cars lighter also involves reducing the weight of the motor. One way to do that is by constructing it from fiber-reinforced polymer materials. A new cooling concept...

Recent technical advances have enabled flywheel energy storage systems (FESS) to become more compact and able to support higher-power applications. Due to their proven...

Spinoff is NASA’s annual publication featuring successfully commercialized NASA technology. This commercialization has contributed to the development of products and services in...

An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot — particulate matter consisting...
