Fluidic Actuators with No Moving Parts

Two new fluidic actuator designs were developed to control fluid flow in ways that will ultimately result in improved system performance and fuel efficiency in to improve the aerodynamic performance of a variety of vehicles. These flow control actuators, often referred to as fluidic oscillators or sweeping jet actuators, utilize the Coanda effect to generate spatially oscillating bursts (or jets). They can be embedded directly into a control surface (such as a wing or a turbine blade) to help reduce flow separation, increase lift, reduce drag, enhance mixing, or increase heat transfer. Recent studies show up to a 60% performance enhancement (such as increased lift or reduced drag) with fluidic actuators.

Embedded Servo Drive Boosts Speed of Packaging Lines

Pfankuch Machinery, based in Ahrensburg, Germany, is a leading manufacturer of friction feeder systems for inserting leaflets and products into sales packaging. An embedded smart servo drive from Metronix (part of the Apex Tool Group in Sparks, MD) has allowed Pfankuch to increase the speed of its latest friction feeder — the SmartFeeder — by 50% while also doubling the positioning accuracy. This offers a massive gain in productivity for the many users of this type of packaging equipment in markets including pharmaceutical, and food and beverage processing. At the same time, the new embedded drive minimizes the hardware costs of the upgrade for Pfankuch, because the drive was adapted for the application, providing a stripped-down product suitable for OEM integration that eliminates numerous expensive components.

Autonomous Robotic Manipulation (ARM)

This sensor-driven, model-based approach can be applied to small-batch manufacturing processes and explosive ordnance disposal. NASA’s Jet Propulsion Laboratory, Pasadena, California Autonomous robotic manipulators have the potential to increase manufacturing efficiency, provide in-home care, and reduce the risk to humans in hazardous situations. The current challenge in autonomous robotic manipulation is to approach the capabilities of dedicated, one-off manipulators in known environments with versatile, inexpensive, and ubiquitous manipulator systems that can operate in a range of environments with only high-level human input.

Sliding Gait for ATHLETE Mobility

A new concept was developed for a walking-driving hybrid in which wheels are repositioned by sliding them along the ground. ATHLETE (All-Terrain Hex-Limbed Extra-Terrestrial Explorer) is a multipurpose mobility platform for planetary surfaces. It is a cross between a wheeled rover and a walking robot, and travels using powered wheels mounted on the end of each of six robotic limbs. Each limb is a fully articulated robotic manipulator with six or seven degrees of freedom.

Motors Power NASA’s Interactive Humanoid Tour Guide

RoboThespian is a programmable, interactive humanoid robot designed to communicate, interact, and entertain. First developed in 2006 by Cornish company Engineered Arts, RoboThespian stands 5'9", with a full range of upper-body movement and human-like eyes. NASA will employ the robot’s third generation as a figurehead — meeting and greeting over 1.5 million visitors per year at its futuristic Cape Canaveral base.
