Motion Control

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. NASA’s Jet Propulsion Laboratory, Pasadena, California 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.

Enabling Microliquid Chromatography by Microbead Packing of Microchannels

The microbead packing is the critical element required in the success of onchip microfabrication of critical microfluidic components for in-situ analysis and detection of chiral amino acids. In order for microliquid chromatography to occur, there must be a stationary phase medium within the microchannel that interacts with the analytes present within flowing fluid. The stationary phase media are the microbeads packed by the process discussed in this work. The purpose of the microliquid chromatography is to provide a lightweight, low-volume, and lowpower element to separate amino acids and their chiral partners efficiently to understand better the origin of life.

Heart Pump with Behind-the-Ear Power Connector

One-third of patients with heart pumps develop infection at abdominal connection. Cardiac surgeons and cardiologists at the University of Maryland Heart Center are part of a multi-center clinical trial evaluating the efficacy of powering heart pumps through a skull-based connector behind the ear. The pumps, called left ventricular assist devices (LVADs), support the heart’s main pumping chamber, the left ventricle. LVADs are implanted in the chest and powered with external batteries. Typically, these devices, which are used for patients with severe heart failure, are powered through an electrical cord connected at the abdomen, where potentially deadly infections can develop.

Custom Drive System Helps Mercedes-Benz Reduce Draft in Convertibles

The AIRCAP® automatic draft stop, offered in the Mercedes-Benz E-Class convertibles, is distinctively different from conventional angular wind deflectors. It is entirely embedded into the car body and completely concealed into the windshield frame when deactivated. In its activated state, an aerodynamically shaped wind deflector extends on top of the windshield without disfiguring the automobile’s aesthetic side line.

Linear Stage Brings Speed and Precision to Semiconductor Inspection

With some of the most demanding quality control regimens of any industry, semiconductor manufacturers use a variety of sophisticated metrology instruments to inspect wafers at each production step. All of these instruments have something in common: They simply will not function without precision motion stages.
