Autonomous Flying Vehicles

MIT’s intelligent aircraft fly, cooperate autonomously

Each UAV is networked with a PC. The setup allows a single operator to command the entire system, flying multiple UAVs simultaneously. Moreover, it requires no piloting skills; software flies the vehicles from takeoff to landing.

The vehicles in MIT’s test platform are inexpensive, off-the-shelf gadgets; they can be easily repaired or replaced with a new vehicle, just as might happen in a real-world scenario involving numerous small UAVs on a long-term mission. The researchers can thus experiment constantly without concern for mishaps with expensive equipment.
…
In addition, the team recently achieved a milestone in autonomous flight: landing on a moving surface. Using “monocular vision,” one of the quadrotors successfully landed on a moving vehicle — a remote-controlled lab cart. A video camera fastened to the UAV uses a visual “target” to determine in real time the vehicle’s distance relative to the landing platform. The ground station then uses this information to compute commands that allow the UAV to land on the moving platform. This technology could enable UAVs to land on ships at sea or on Humvees moving across terrain.

Gel Stops Bleeding in Seconds

Self-assembling gel stops bleeding in seconds by Robert Adler:

Swab a clear liquid onto a gaping wound and watch the bleeding stop in seconds. An international team of researchers has accomplished just that in animals, using a solution of protein molecules that self-organise on the nanoscale into a biodegradable gel that stops bleeding.
…
Their work exploits the way certain peptide sequences can be made to self-assemble into mesh-like sheets of “nanofibres” when immersed in salt solutions.
…
Still, they caution that extensive clinical trials are needed to make sure the materials work properly and are safe. The MIT researchers hope to see those crucial human trials within three to five years.

Data on Grad Students

Diversity Up for Grad Students provides some interesting stats. Among the most interesting is that Engineering grad students in the USA are 52% USA citizens and permanent residents while overall 84% of grad students are (other fields, for example, health sciences 92%, business 83%, biological sciences 83%).

Innovative Science and Engineering Higher Education

CMU student with small robot

Popular Mechanics provides glimpses of 10 cutting-edge science and engineering programs in: 10 Radically Innovative College Programs. Of course Olin College is highlighted again, as they should be: Olin Engineering Education Experiment. They also spotlight: University of California, Irvine; Florida State University, Panama City; Rocky Mountain College of Art + Design; Tufts University; MIT, The Ohio State University; Louisiana State University; Art Center College of Design; and Carnegie Mellon University:

CMU’s Robotics Institute in Pittsburgh is the world’s biggest academic robotics research center. Undergrads minoring in the subject take courses such as Introduction to Robotics, in which the weekly homework assignment is to build LEGO robots demonstrating that week’s concepts. “If the robot works, they get their A,” says Howie Choset, who teaches the course. But the real fun happens in the research labs, where students work on projects such as a slithering snake robot for search-and-rescue missions.

Students also participate in a dazzling array of competitions, such as the RoboCup, which pits teams of Sony AIBO robot dogs against each other in soccer. The highlight of the year is probably the Mobot Races at the CMU Spring Carnival. “Mobot is more important than the football team,” Choset says.

Tour the Carnegie Mellon Robotics Lab. One theme I see is the focus on projects – versus learning things for a test. A good thing. I would imagine some might worry it is too fun and not enough reading books ðŸ™‚ I think students will learn far more from a well crafted experiential education system. But it is a challenge to put that together well. We will all benefit from those that attempt to do so now.

Science and Engineering Degrees – Career Success

Fortune magazine has selected the 50 most powerful women in business and selected 4 rising stars. It is another example (granted just an anecdote) illustrating that science and engineering degrees can pave the way to career success (also see: Top degree for S&P 500 CEOs? Engineering).

Shona Brown, Senior Vice President, Business Operations, Google, has a bachelor of computer systems engineering degree from Carleton University in Canada and a master’s degree in economics and philosophy from Oxford University as a Rhodes Scholar. She received her Ph.D. and Post-Doctorate from Stanford University’s Department of Industrial Engineering and Engineering Management. Our management blog mentioned her last month: Chaos Management (by design) at Google – and her book, Competing on the Edge: Strategy as Structured Chaos.

Adriane Brown, President and CEO, Transportation Systems, Honeywell. Degree: environmental health from Old Dominion University.

Padmasree Warrior, EVP, Chief Technology Officer, Motorola – “received a M.S. degree in chemical engineering from Cornell University, and a B.S. degree in chemical engineering from the Indian Institute of Technology (IIT) in New Delhi, India.”

Engineers Save Energy

Dr. Rosenfield - Fermi Award Winner

Arthur Rosenfeld the 2005 Enrico Fermi Award Winner which is the “government’s oldest award for scientific achievement” according to the Department of Energy. I question that, and on another page they say “one of the oldest…”

“Dr. Rosenfeld is one of the ‘founding fathers’ of energy efficiency, and the legacy of his research and policy work is an entire new energy efficiency sector of our economy, which now yields an astounding annual savings of around $100 billion, and growing.”
…
Rosenfeld received his Ph.D. at the University of Chicago in 1954 and was Nobel Laureate Enrico Fermi’s last graduate student.
…
In 1973, when OPEC embargoed oil sales to the West, Dr. Rosenfeld redirected his career. He recognized the potential for energy savings in the building sector, which uses one third of U.S. primary energy and two-thirds of our electricity. In 1975, he founded a program which grew into the Center for Building Science at DOE’s Lawrence Berkeley National Laboratory.
…
The U.S. National Research Council (NRC) has estimated that energy efficiency improvements developed solely at DOE’s National Laboratories, saved the U.S. $30 billion between 1978 and 2000

Great stuff. Another great example of how much good scientists and engineers can do. And also a good reminder of the economic benefits that are less obvious – such as increasing energy efficiency.

RI FIRST

Ocean State to enlist all high schools in robotics challenge

tarting next year, state officials say, students at all 67 of Rhode Island’s public, charter and career and technical high schools will have a chance to participate in the FIRST Vex Challenge, a robot-building competition. The announcement last week makes the Ocean State the first to involve all its public high schools in the challenge, which involves building a robot able to complete a specific set of tasks.
…
Throughout the challenge, students must maintain an engineering notebook to track their progress, successes and challenges. During the build period, teams work as a group to brainstorm solutions, design a robot to do various tasks, and build and test their designs. The projects culminate in competitions designed to be fun, high-energy, sports-like events with judges and awards.

FIRST is an exciting program we have mentioned before: For Inspiration and Recognition of Science and Technology (FIRST). Dean Kaman (R&D Magazine’s 2006 Innovator of the Year) founded the program and it continues to do a great job of capturing the natural desire for people to learn and create. Learn about regional events this school year.

UK Young Engineers Competitions

Young Engineers is a organization in the United Kingdom that supports engineering events and competitions. Established in 1984, in 2005 there were 1,100 active clubs with over 18,000 club members (36% female).

The site is packed with information on events and especially photos. See the Young Engineer for Britain Galleries and Robotic Games.
