US army in 2020

U.S. technologists have revealed that the country’s military has plans to have about 30 per cent of the Army comprised of robotic forces by approximately 2020.

Doug Few and Bill Smart of Washington University in St. Louis say that robots are increasingly taking over more soldier duties in Iraq and Afghanistan, and that the U.

S. Army wants to make further additions to its robotic fleet.
They, however, also point out that the machines still need the human touch.
“When the military says ‘robot’ they mean everything from self-driving trucks up to what you would conventionally think of as a robot. You would more accurately call them autonomous systems rather than robots,” says Smart, assistant professor of computer science and engineering.

All of the Army’s robots are teleoperated, meaning there is someone operating the robot from a remote location, perhaps often with a joystick and a computer screen.

While this may seem like a caveat in plans to add robots to the military, it is actually very important to keep humans involved in the robotic operations.

“It’s a chain of command thing. You don’t want to give autonomy to a weapons delivery system. You want to have a human hit the button. You don’t want the robot to make the wrong decision. You want to have a human to make all of the important decisions,” says Smart.

The technologist duo says that researchers are not necessarily looking for intelligent decision-making in their robots. Instead, they are working to develop an improved, “intelligent” functioning of the robot.

“It’s oftentimes like the difference between the adverb and noun. You can act intelligently or you can be intelligent. I’m much more interested in the adverb for my robots,” says Few, a Ph.D. student who is interested in the delicate relationship between robot and human.

He says that there are many issues that may require “a graceful intervention” by humans, and these need to be thought of from the ground up.

“When I envision the future of robots, I always think of the Jetsons. George Jetson never sat down at a computer to task Rosie to clean the house. Somehow, they had this local exchange of information. So what we’ve been working on is how we can use the local environment rather than a computer as a tasking medium to the robot,” he says.

Few has incorporated a toy into robotic programming, and with the aid of a Wii controller, he capitalizes on natural human movements to communicate with the robot.

According to the researchers, focussing on a joystick and screen rather than carting around a heavy laptop would help soldiers in battle to stay alert, and engage in their surroundings while performing operations with the robot.

“We forget that when we’re controlling robots in the lab it’s really pretty safe and no one’s trying to kill us. But if you are in a war zone and you’re hunched over a laptop, that’s not a good place to be. You want to be able to use your eyes in one place and use your hand to control the robot without tying up all of your attention,” says Smart.

Devices like unmanned aerial vehicles, ground robots for explosives detection, and Packbots have already been inducted in the military.

“When I stood there and looked at that Packbot, I realized that if that robot hadn’t been there, it would have been some kid,” says Few. (ANI)

Bagaimana dunia di masa yang akan datang ? terutama teknologi militer menggunakan robot.

NASA's LRO takes extreme close-up of eclipse

NASA's LRO takes extreme close-up of eclipse

Orbiting about 31 miles above the lunar surface, NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft will get a "front-row seat" to the total lunar eclipse on June 15, says Noah Petro, Associate Project Scientist for LRO at NASA's Goddard Space Flight Center in Greenbelt, Md.
A lunar eclipse happens when the moon passes into Earth's shadow, and a total lunar eclipse occurs when Earth completely blocks the sun, causing the moon to darken and appear to change color. However, the moon doesn't go completely dark because Earth's atmosphere bends (refracts) indirect sunlight toward the moon, giving it dim illumination. Since indirect sunlight must travel through Earth's atmosphere before reaching the moon, any clouds or dust in the atmosphere will block certain colors in the sunlight, causing the moon to seem to change color, frequently turning it yellow, orange, or red. The exact color varies from eclipse to eclipse, depending on the weather at the time.
The June 15 lunar eclipse will be visible, at least in part, from around the world except North and Central America. "However, LRO will be observing, so eventually everyone will get to see a close-up of it," says Petro. The eclipse begins at about 17:24 Universal Time (UT), will be darkest from around 19:22 UT to 21:02 UT, and ends a bit after 23:00 UT. During this eclipse, the moon's orbital path will take it close to the center of the darkest part of Earth's shadow, called the umbra, so the deepest part of the eclipse will last a long time -- just over an hour and 40 minutes. Unlike a solar eclipse, a lunar eclipse is safe to view without special equipment.
LRO's Diviner Lunar Radiometer instrument will record how quickly different areas on the moon's day side cool off during the eclipse. Since large boulders cool more slowly than a fine-grained or dusty surface, Diviner will be able to see what areas are covered with boulders and what regions are blanketed by dust.
"This is an unprecedented opportunity to learn more about the uppermost few millimeters of the moon," says Diviner Principal Investigator David Paige of the University of California, Los Angeles. "Diviner plans to operate continuously during the entire eclipse period, targeting ten specific regions. The ten sites represent a diverse selection of lunar terrains. Some consist of fine dust, others are rocky, and there are a variety of compositions including dark, iron-rich lunar maria and light, iron-poor lunar highlands. Diviner will target these features before, during, and after the eclipse, which will allow us to observe how these different surfaces respond to the sudden drop in temperature."
"The moon turns slowly -- a complete day-night cycle lasts more than 29 Earth days," says Petro. "So lunar dusk and dawn last a long time, and normally the lunar surface cools down and heats up slowly. This eclipse is a special opportunity to see what happens if you 'switch off' the sun relatively quickly. It's like taking a pie out of the oven and throwing it into the freezer without letting it cool down first. We want to see how the moon's surface responds to this abrupt temperature change," said Petro.
The Diviner observations will complement surface roughness measurements from LRO's other instruments because Diviner can get hints at what lies just beneath the surface, according to Petro. "LRO's camera and laser altimeter might see a flat, dusty region, but if Diviner sees that it is cooling unusually slowly, that tells us large blocks of material are hidden beneath a thin layer of dust," said Petro.
The eclipse presents unusual conditions for LRO, according to Petro. LRO runs on solar energy, with battery back-up for power during its approximately hour-long journey over the moon's night side each orbit. LRO's other instruments will be turned off to conserve energy during the long night imposed by the eclipse, and the spacecraft will have to endure a longer period of deep cold.
"It will be like taking my car off-road. It's not really built for that, but it can handle limited excursions," said Petro. This will be the first time LRO operates an instrument during a total lunar eclipse, according to Petro, and it will be the longest eclipse during the mission's expected lifetime.
Paige and his Diviner team will lead the observations, with funding from NASA's Science Mission Directorate, NASA Headquarters, Washington. NASA Goddard assembled and manages LRO.
