Artificial antenna helps ’cockroach robot’ scurry along walls

Student-made device sends obstacle warnings to mechanical bug’s brain

Can a robot learn to navigate like a cockroach? To help researchers find out if a mechanical device can mimic the pesky insect’s behavior, a Johns Hopkins engineering student has built a flexible, sensor-laden antenna. Like a cockroach’s own wriggly appendage, the artificial antenna sends signals to a wheeled robot’s electronic brain, enabling the machine to scurry along walls, turn corners and

Molecular wires & corrosion control boost performance of conductive adhesives

Replacing lead-based solder

Electrically conductive adhesive (ECA) materials offer the electronics industry an alternative to the tin-lead solder now used for connecting display driver chips, memory chips and other devices to circuit boards. But before these materials find broad application in high-end electronic equipment, researchers will have to overcome technical challenges that include low current density.

Using self-assembled monolayers – essentially molecular

Students Create Proximity Sensor System for Wheelchair-Bound Woman

A team of first-year engineering students at Elizabethtown College have created a proximity sensor system that will help a disabled woman better maneuver her power wheelchair.

The Audible Warning Sonic Sensor System, which is mounted to and powered by Melissa Sneath’s wheelchair, produces a warning sound when she is approaching an object or wall. The sound changes as she gets closer to the object, allowing her to correct her course and avoid a collision.

“As a result of h

Duke University engineers join ’Red Team’ robotic vehicle team

Students from Duke University’s Pratt School of Engineering are partnering with Carnegie Mellon University’s “Red Team” in an effort to win a $2 million prize from the Defense Advanced Research Projects Agency (DARPA). All they have to do is complete the toughest ground course ever devised for a self-guided robotic vehicle.

The contest, called the DARPA Grand Challenge, is a race between fully self-guided ground vehicles to be conducted in the Southwestern United States on Oct. 8,

UF-developed detectors help guard against foam flaws in shuttle’s fuel tank

The engineers who built the massive external fuel tank that will power the shuttle Discovery into orbit this spring used sophisticated X-ray detectors developed by UF researchers to reduce the chance of a defect in the foam insulation covering the tank. The detectors, first invented as a new technology to find land mines, can identify tiny gaps, or air-filled voids, in the insulating foam without causing any damage. It is believed that such a gap – possibly located between the foam and the ta

New Lab Delves into Plants for Fuels

A new integrated facility designed to give scientists unprecedented insights into the chemical and biological reactions which can transform renewable plant and waste materials into useful sources of energy was dedicated yesterday at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL).

Called the Biomass Surface Characterization Laboratory (BSCL), the $2.85 million facility features an array of electron and optical microscopes, and other advanced res
