Aldebaran Robotics' Nao

NAO is equipped with bells and whistles. It has limbs with 25 degrees of freedom, operable hands, stereo vision, voice recognition and synthesis and it’s driven by a programmable Linux operating system. You can progam NAO in either a graphical environment or code environment (Urbi scripting language, considered pretty easy to learn).

The programming environments of this bot are made to suit all ranges of skill. Of course, for average users they will definitely choose to program it in GUI mode. For those geeky ones, will want to try the coding environment. You can also program it via WiFi.

Besides being able to add software and behaviors via the bot’s programmable OS, you can also have little customization for the hardware, such as swapping its head out. The Nao is expected to hit the market in end of 2009, and as mentioned, the price shall be between $15,000 and $16,000. The Nao robot is only 23-inch tall, but he should be a pretty amusing one, since he carries all the bells and whistles. We have a video to show the Nao bot in action.

NATO to police Libya no-fly, compromises on command

NATO to police Libya no-fly, compromises on command

By Maria Golovnina and Michael Georgy

TRIPOLI (Reuters) – NATO said it would enforce a Libya no-fly zone but stopped short of taking full command of U.N.-backed military operations to protect civilians from forces loyal to Libyan leader Muammar Gaddafi.
Coalition jets pounded targets in southern Libya on Thursday but failed to prevent government tanks re-entering the western city of Misrata, whose main hospital was besieged by armor and government snipers.
Western commanders hope rebel forces in eastern Libya will overthrow Gaddafi, but the return of tanks to Misrata under cover of darkness highlighted the difficulties they face in trying to force the Libyan leader to cease fire.
Rebels, who have set up an alternative government in their eastern stronghold in Benghazi, say they needed more ammunition and anti-tank weapons if they are to end Gaddafi's 41-year rule.
"We need arms and ammunition. This is our only problem," rebel military spokesman Colonel Ahmed Bani told a briefing.
France, Britain and the United States have spearheaded enforcement of the Libya no-fly zone imposed last week by the U.N. Security Council, which authorized "all necessary measures" to protect Libyan civilians against Gaddafi's forces.
But differences over the scope the U.N. resolution gave for military action against Gaddafi's army led to days of heated arguments within NATO about its role in the operation.
Turkey had wanted to be able to use its NATO veto to limit military operations against Libyan infrastructure and avoid casualties among Muslim civilians from air raids.
France argued NATO's command structure should run day-to-day military operations, leaving political control with an ad hoc steering group of coalition members, including the Arab League.
France believes having NATO in full charge would erode Arab support because of U.S. unpopularity in the Arab world. After four days of argument, NATO ambassadors in Brussels reached a deal of sorts.
"At this moment, there will still be a coalition operation and a NATO operation," NATO Secretary-General Anders Fogh Rasmussen told reporters. The alliance's mandate did not extend beyond enforcing the U.N. arms embargo and no-fly zone, he said.
NATO officials said a decision was expected on Sunday on whether to broaden the mandate to allow the organization to take command of all military operations and attack ground targets in the oil-producing country, in order to protect civilian areas threatened by Gaddafi's forces.
Earlier, Turkish Foreign Minister Ahmet Davutoglu had told reporters: "The operation will be transferred completely to NATO and there will be a single command and control."
The United States, embroiled in Iraq and Afghanistan, is keen to step back and play a supporting role in Libya, preserve alliance unity and maintain the support of Muslim countries for the U.N.-mandated intervention.
U.S. Secretary of State Hillary Clinton said military planners had been authorized to take on the "broader civilian protection mission" and NATO was well suited to do so.
The number of U.S. aircraft flying missions had dropped significantly as other nations increased their role, she said.
U.N. Secretary General Ban Ki-moon, for his part, told the Security Council there was no evidence Tripoli was complying with U.N. resolutions. His special envoy to Libya had warned Gaddafi's government of possible "additional measures" if Libya failed to comply with the ceasefire demand.
AIR STRIKES
The Libyan government denies its army is conducting any offensive operations and says troops are only defending themselves when they come under attack.
State television said Western jets struck military and residential areas of the capital Tripoli for a sixth straight night on Thursday, prompting bursts of anti-aircraft fire.
Libya said the civilian death toll from five days of coalition air strikes had reached almost 100 and accused Western governments of fighting on the side of the rebels. The toll could not be independently verified.
Western air strikes had earlier on Thursday destroyed government tanks outside Misrata, some 200 km (130 miles) east of Tripoli, but other tanks inside the city were not hit, a resident said.
Gaddafi's tanks slipped back into the city on Thursday and shelled the area near the hospital, residents and rebels said.
Government spokesman Mussa Ibrahim said Libyan forces were in control of the city of 300,000 people, with only a hard core of rebels holding out.
But opposition spokesman Abdulbasset Abu Mzereiq said by telephone that rebels were still fighting there, and had killed 30 snipers who had been picking off civilians from rooftops in the town. Government warships had left the port.
Rebels and besieging government forces continued to clash around the eastern frontline town of Ajdabiyah, said Abu Musab, who left the town by car with his family of 10.

Air traffic controller asleep as planes land

Federal aviation officials are reviewing air traffic controller staffing at airports around the United States after two airliners landed at Reagan National Airport without clearance from the airport tower because they were unable to raise anyone there. An aviation official said an air traffic supervisor - the lone controller on duty around midnight local time when the incident occurred - had fallen asleep. The pilots of the two planes were in contact with controllers at a regional Federal Aviation Administration facility about 64km away in Virginia, Peter Knudson, a spokesman for the National Transportation Safety Board, said yesterday.

Tips and Techniques How to strengthen signal WiFi / Wireless

Tips and Techniques How to strengthen signal WiFi / WirelessImprove Wireless Connections

Wireless Router no longer be new, and perhaps most internet users already have this tool at home to share the wireless internet connection (wireless).This time, we will try to discuss the problems / constraints that may often faced by users of the wireless router that is on the signal strength on the wireless router.How to make Wi-Fi signal could reach an optimal or a wider area? Here are a few things to note:1. Place the Wireless Router at the center of the room
Since most wireless routers use a type of omni directional antennas (spread to all directions), a wireless router should be placed in the middle of the room so that it can reach every corner of the room.
2. Note the placement of wireless routers
Do not place the wireless router on the floor, adjacent to the wall or having contact with objects that contain iron (metal) because all these things will reduce the existing signal strength. The closer you put the three things above, will be the weaker signal.
3. Replace existing antennas on the Wireless RouterAs we said in point no. 1 that as a router using Omni Directional antenna types that are spread to all directions. If indeed you often use in the entire room or corner of the antenna of this type is perfect but if you're more likely to use it in one place, perhaps the replacement of the antenna can further strengthen the signal.

One example type of antenna to the problem above is the High Gain Antenna in which the nature of its spread to only one point so that your signal will get better but we suggest you can not often change places.
4. Replace the Wireless network adapter with a betterIf you use a computer (not notebook), you must install the Wireless Network Adapter in it. Make sure that the Network Adapter you are using is good enough and can also replace existing antennas with better quality like the High Gain Antenna above.


5. Add Wireless Repeater if necessaryAlthough the antenna has been replaced with something better does not mean you can reach more distant locations. For that sometimes we need an additional tool called the Wireless Repeater.

Wireless Repeater useful to strengthen and extend the existing WiFi signal so that its reach into broader, eg with regular antenna, signal coverage reaches only 100 m but with this, signal coverage can be 2x longer is 200m or more.But indeed for the addition of a tool like this, we have to spend quite a lot of money.
6. Replacing an existing Wireless ChannelWiFi Signal can run on several channels at once, if you feel that there is less good signal and found a lot of channels in it, you should change to a smaller channel.And no need to worry with this channel because replacement computer / notebook will detect and adjust automatically when there is change channels.
7. Keep Wireless Router from certain electronic devicesWifi signal work in the 2.4 GHz frequency, so you should keep your wireless router from an electronic device that uses the same frequency.


For example telephone cordeless (without cable) which usually also use the same frequency is 2.4 GHz. When this happens, you inevitably have to replace it with a cordless phone that uses different frequencies such as 900 MHz cordless phone or replace a regular telephone, this is a cheaper solution.
8. Always update your firmware for the Wireless RouterUsually every well-known manufacturers such as D-Link, Linksys and others are always released the latest firmware for your router to router performance to be better. Do these firmware upgrades are usually provided on their website.
9. Use the same brand for your wireless networkAlthough the outline, use a different brand for the network devices (routers, adapters) does not have a problem but usually the signal would be better if we use a single brand.For example, your router brand Linksys, Wireless Adapter should be used in the computer also uses the same brand.
10. Upgrading the type of 802.11b WiFi to 802.11gWe're sure most owners Wifi network is already using the format type G but if you are still using 802.11b type then you should replace or at least make all WiFi network using the same format.Sure there 802.11n promises faster transfer speeds and further range, but it should be noted that the format of N is still not certified.
