NAO , French robot that is ahead of the Japanese



 Developed by Aldebaran Robotics , the company of the French Bruno Maisonnier ,
 NAO humanoid robot is 58 cm high , to be a companion
 benevolent in your homes . Since its birth in 2006, he has continued to EVO-
 luer to one day become your friend.
NAO is a small character which is a unique combination of
 the Hardware and Software. It consists of sensors , motors
 and software controlled by its operating system dedicated NAOqi .
 Walking NAO uses a simple dynamic model and pro-
 quadratic programming . It is stabilized from information
 sent back by the joints of the sensors. This makes the
 running strong and resistant to small perturbations and allows
 to absorb the oscillations of the torso in the frontal and lateral planes .
 NAO can walk on different surfaces such as carpets or
 carpet , tiles or wood floors and can also make the transition
 tion between these types of surfaces during operation .

NAO movement module is based on the inverse kinematics
 widespread . This means that when you ask NAO to extend
 the arm , it will look as the joints of his arms and legs
 are taken into account . The fall Manager protects NAO .
 Once a fall is detected, all motion tasks are
 killed and , according to management, the NAO arm take a position
 tion protection.
 NAO has two 1220P cameras capable of capturing up to 30
 fps. They allow it to monitor , store and
 recognize images and faces. He can recognize the personal
 not talking to him or find a ball or even more complex objects.
 The first camera , located in the front NAO , scans the horizon for
 the second , located at the mouth , scans the environment
 immediately.
 One of the main goals of humanoid robots is to interact with
people. Sound localization allows a robot to identify the direction
 sounds. When a nearby source emits a sound , each of the four mid
 crophones NAO receives sound waves at times slightly different
 ent . For example, if someone talks to NAO on the left , the sound wave
 corresponding first arrives on the left microphone, then the
 front and rear microphones few milliseconds later , and finally
 on the right microphone.

In addition to cameras and microphones , NAO has capacitive sensors
 arranged on the top of his head in three sections as well as its
 hands. You can give NAO information through to the touch
 expensive. Pressing told him to stop, for example, but the sensors can
 wind also be used as a series of buttons to trigger
 associated actions . The system is equipped with LEDs which indicate the
 contact type. NAO is also equipped with two sonar channels , two
 transmitters and two receivers . They allow NAO estimate distances
 obstacles in its environment. The detection range is from 1 cm
 3 meters.
 NAO currently support Wi-Fi and Ethernet. It can be used on
 WPA and WEP networks, which allows it to connect to most re-
 domestic and corporate networks . You can manage and program
 Sea NAO using any network computer. Here are some
 Examples of applications created by the NAO users :
 - From its IP address , NAO can know where it is and you Don-
 ner personalized weather report .
 - Ask a question about NAO to a topic, it connects to Wikipé-
 dia and you read the article.
 - Connect NAO to an audio stream and you can stream a radio station.
 Using infrared, NAO can communicate with others and NAO
 other devices operating with infrared. It can for example turn
 TV, video game console or DVD / Blu -ray player.
 With its experience in developing embedded systems
 robotic platforms , Aldebaran Robotics wants to share his tools
 multi-platform construction, its communication library centers
 tral and other essential modules with researchers, developers and
 emerging projects in humanoid robotics . In more than 70 countries, it is
 installed in the computer classes or science , from primary to
 university. Through it , students learn programming ma-
 playful and applied manner . They plan to do the walk , reach back
 per small items , or for dancing . He then conquered
 developer communities who see him as a powerful support and
 incredibly expressive for creating applications. Imagine
 all that is possible to do NAO . It's a new world
 Applications that opens to them ... for the next step which is its
 marketing to the general public .
