Senior Operations LLC Metal Bellows (Sharon, MA) offers the DELTA P high-pressure bellows seal for use in injection valve applications. It is capable of withstanding high external system pressures, while maintaining low differential pressure across the edge-welded bellows. This feature enables the bellows to be designed with thinner...

In order to perform human-like movement, an actuator is placed at each degree of freedom (DOF) in a humanoid robot. Additionally, these actuators must be packaged in an arrangement that approximates human structure and appearance. In this innovation, a rotary actuator assembly incorporates a brushless DC motor, a gear...

The first step in implementing the capability to test sensitive launch vehicle instruments in a combined environment has been completed. The test environment consists of specific vibration spectra induced under sustained Gs, using NASTAR’s ATFS-400 centrifuge. Fixtures allow mounting...

As NASA moves towards developing technologies needed to implement its new Exploration program, studies conducted for Apollo in the 1960s to understand the rollover stability of capsules landing are being revisited. Although rigid body kinematics analyses of the rollover behavior of...

Advancement in space exploration necessitates deep throttling of liquid cryogenic rocket engines. Both lunar and Martian robotic and human exploration require engines that can be deep throttled,can start and restart, have a long life, and require minimal maintenance. An engine that is capable of deep throttling at low...

This innovation consists of an analog controller, diamond-shaped patch actuator, and point sensors (such as accelerometers). The actuator is designed to couple to the flexural response of the structure in the same manner as a group of point sensors. This results in a co-located transducer pair. The signals...

Three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006. These satellites provide a test bed for development and research, each having its own power, propulsion,...

Researchers at MIT and Cornell University will provide photographers with squadrons of small, light-equipped autonomous robots that automatically assume the right positions for photographic lighting. With the new system, the photographer indicates the direction from which the rim light should...

Graduate students from the University of Colorado Boulder are designing robots to work in a deep-space habitat, tending gardens and growing food for astronaut explorers.The team's entry in the eXploration HABitat (X-Hab) Academic Innovation Challenge is called "Plants Anywhere: Plants Growing in Free...

Purdue University researchers have developed a technique to embed a liquid-alloy pattern inside a rubber-like polymer to form a network of sensors. The approach may be used to produce "soft machines" made of elastic materials and liquid metals.Such an elastic technology could be used to create robots with...
