Wireless Ultrasonic Inspection Propulsion System
During inspection of pressure vessels and other large structures, an industry-accepted fixture is used to hold the search unit a predetermined distance from the area of interest under inspection. This fixture is then moved manually around the area of interest so that data can be collected and stored...
NASA Spinoff: Sensors/Data Acquisition
Spinoff is NASA's annual publication featuring successfully commercialized NASA technology. This commercialization has contributed to the development of products and services in the...
Briefs: Mechanical & Fluid Systems
A component-level DC transformer was developed in which no alternating currents or voltages are present. It operates by combining features of a homopolar motor and a homopolar generator, both DC devices, such that the output...
Articles: Aerospace
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,...
Briefs: Robotics, Automation & Control
A novel mechanical control system has been proposed for spherical robots to be used as multifunctioning sensor buoys in areas with ambient forces such as winds or currents....

Hybrid Rotor Compressor for Natural Gas Extraction
Jeremy Pitts and Pedro Santos, OsComp Systems, Boston, MA
Natural gas is a booming industry in the U.S. and represents a bridge energy solution to a...
Briefs: Mechanical & Fluid Systems
One of the major technical problems deep-space optical communication (DSOC) systems need to solve is the isolation of the optical terminal from vibrations produced by the spacecraft...
Briefs: Mechanical & Fluid Systems
The figure depicts selected aspects of a six-legged robot that moves by hopping and that can be steered in the sense that it can be launched into a hop in a controllable direction. This is a prototype of...
Briefs: Mechanical & Fluid Systems
Modular exploratory robotic vehicles that will be able to reconfigure themselves in the field are undergoing development. These vehicles at the initial concept stage were described in...

Converting From DDOR SASF to APF
A computer program called “ddor_sasf2apf” converts delta-door (delta differential one-way range) request from an SASF (spacecraft activity sequence file) format to an APF (apgen plan file) format for use in the Mars Reconnaissance Orbiter (MRO) mission-planning-and- sequencing process. The APF is used as an...

Low-Friction, High-Stiffness Joint for Uniaxial Load Cell
A universal-joint assembly has been devised for transferring axial tension or compression to a load cell. To maximize measurement accuracy, the assembly is required to minimize any moments and non-axial forces on the load cell and to exhibit little or no hysteresis. The requirement to...
Briefs: Photonics/Optics
An improved version of an optoelectronic apparatus for measuring distances of the order of tens of feet with an error no larger than a small fraction of an inch (a few millimeters) has...
Briefs: Motion Control
Linear back-drive differentials have been proposed as alternatives to conventional gear differentials for applications in which there is only limited rotational motion (e.g., oscillation). The finite nature of...
Briefs: Mechanical & Fluid Systems
A family of rugged, modular, reconfigurable, instrumented robotic vehicles has been proposed for use in exploration of the surfaces of Mars and other remote planets. These or similar vehicles could...
Briefs: Robotics, Automation & Control
Robots with multiple-link arms that could reach through narrow openings into hidden cavities are undergoing development. Called "multifunction dexterous boro-robots" (MDBRs), these robots would...
Briefs: Robotics, Automation & Control
Lightweight, inflatable robotic vehicles (rovers) that superficially resemble beach balls and that could be driven by wind and/or electric power are undergoing development. These rovers were conceived...
