Prototype robots autonomously strip paint from aircraft using lasers

By - November 26, 2012 15 Pictures
If you think stripping paint off an end table can be a messy, time consuming job, imagine removing paint and other coatings from an aircraft like the C-130 transport plane. Tasked with developing a robotic system that would take such a chore out of the hands of maintenance personnel, Carnegie Mellon University's National Robotics Engineering Center (NREC) and Concurrent Technologies Corporation (CTC) of Johnstown, Pennsylvania, developed a team of robots that gets the job done – using laser beams, no less.

Ultra-sensitive laser-enabled accelerometer could find its way into consumer products

By - October 19, 2012 1 Picture
As any smartphone aficionado knows, the accelerometer is one of the key sensors within the device – it allows the phone to know when and by how much it’s been moved. Accelerometers also have many other applications, being major components of things like navigation systems, various automotive systems, and image stabilization systems in cameras. Now, researchers from the California Institute of Technology are developing a laser-based accelerometer, that they claim should offer much better performance than is currently possible. Read More

Ministry of Defence developing new anti-laser eyewear

Laser pointers may be great fun to tease the cat with, but for pilots they are a major hazard. The United States FAA reports over 2,000 incidents every year of planes having lasers pointed at them - some of them powerful enough to pop a balloon. To combat the danger that lasers pose to aviation, the U.K. Ministry of Defence (MoD) is developing new eye wear that can filter out a wide range of laser wavelengths. Read More

Regular green laser pointer used to detect hazardous chemicals

By - October 11, 2012 2 Pictures
Hand-held laser pointers can now be used for something else besides doing presentations, projecting images of microorganisms, and disabling satellites. Next week, a group of scientists from Israel’s Ben-Gurion University of the Negev will be presenting a compact device that they created, which uses a garden-variety green laser pointer to detect dangerous substances such as explosives.

SMART tool compensates for surgeons' hand tremors

By - September 28, 2012 1 Picture
No matter how steady you try to hold your hand, it will still tremble several times a second, moving a distance roughly the same as the thickness of a sheet of paper each time. While that might not matter much for the average person, it can be a very big deal to surgeons performing fine-scale surgery on things like eyes or nerve fibers. While there are experimental robotic devices to help smooth out the shakes, researchers from Johns Hopkins University have come up with something else – a surgical tool with a jiggling tip.

NES Zapper Laser packs a punch

Remember the classic NES Zapper, as used in games like Duck Hunt? Well, an intrepid tinkerer at North Street Labs hacker space in Portsmouth, Virginia, has taken that same harmless toy and retrofitted it with a powerful laser. While not quite deadly enough to take out a real life mallard, you wouldn't want to point the NES Zapper Laser toward a TV either, as it's capable of doing considerable damage to whatever it shoots.
