Having placed third in the prestigious DARPA Urban Challenge in 2007, engineering students from Virginia Tech have returned to the forefront of autonomous vehicle development by designing and building four GUSS (Ground Unmanned Support Surrogate) vehicles. Able to carry 1800 lbs and designed to resupply and evacuate troops in the field as well as reduce the load carried by them, the vehicles are due to make their debut at the impending 2010 Rim of the Pacific (RIMPAC)war games in Hawaii.  Read More

Students at Virginia Tech's Unmanned Systems Laboratory are perfecting an autonomous helicopter they hope will never be used for its intended purpose. Roughly six feet long and weighing 200 pounds, the re-engineered aircraft is designed to fly into American cities blasted by a nuclear weapon or dirty bomb. Its main mission would be to assist military investigators in detecting radiation levels, mapping and photographing damage after such an attack.  Read More

Competition is underway in the Department of Energy’s (DoE) Solar Decathlon, in which 20 teams of college and university students compete to design, build, and operate the most attractive, effective, and energy-efficient solar-powered house. The house designs entered in the competition not only capture heat and light from the sun, but also integrate design features to take advantage of cooling breezes and shading. By combining these proven energy efficient designs with the latest off-the-shelf technology, the teams aim to create homes that reduce utility bills and meet all their energy needs, while providing all the comforts of home.  Read More

Current heat treatments for human tumors, such as radiofrequency, have shown promising results over the last couple of decades, even though they apply only a single-point of heat to the tumor. However, a new technique could prove much more effective by using nanotubes to apply heat throughout the tumor. Scientists found that by injecting the man-made, microscopic carbon tubes into tumors and heating them with a quick, 30-second zap of a laser, they were able to effectively kill kidney tumors in nearly 80 percent of mice.  Read More

Recent technological developments are presenting increasing opportunities for blind and vision impaired people to interact with the world in ways not previously possible. However, many everyday acts we take for granted such as driving a car remain out of reach. That’s well on the way to changing thanks to a development by a team of students at the Virginia Tech University, who have designed a car that allows blind and visually impaired people to take the wheel and drive unassisted.  Read More

Researchers at the Robotics and Mechanisms Laboratory at Virginia Tech have designed a series of autonomous serpentine robots that are able to climb poles and inspect structures too dangerous or inaccessible for humans. The robots coil themselves around a beam and roll upward using an oscillating joint motion, gathering important structural data with cameras and sensors.  Read More

March 28, 2007 Brake lights on automobiles are limited in the information they can convey - you're either stopping or you're not. Having some indication of just how hard the driver in front is pressing the pedal would undoubtedly add to road safety, and that's the thinking behind this intelligent brake light system developed by researchers at Virginia Tech’s College of Engineering.  Read More

Gravia uses a slowly sinking weight to charge 10 high-output LEDs, which fire into the acrylic lens and create a diffuse light output of 600-800 lumens, roughly equal to a 40-watt incandescent bulb. The LEDs are activated only a few seconds after the process begins, and the entire operation is silent.  Read More

October 6, 2005 The DARPA Grand Challenge National Qualification Event (NQE) Is finished and 23 robotic vehicles have been selected to compete in the Grand Challenge final event this coming Saturday, October 8, in the Mojave Desert near Primm, Nevada. The finalists will traverse a rugged desert course that features lakebeds, narrow desert roads, tight turns, tunnels, gateways and treacherous mountain passes. The actual course will not be revealed to teams until two hours before the event begins at approximately 6:30 a.m. (PDT). The team whose vehicle traverses the entire course the fastest in under ten hours will win US $2 million. Dan Christian attended the NQE and filed this report. Dan will also be reporting for Gizmag from what promises to be one of the most significant automotive races in history.  Read More
