An initial performance experiment has taken place in Berkshire, England, with the purpose of testing and recognizing intelligent thinking tendencies at robots. During the experiment, five robots have maintained free conversations for several minutes.
Researchers from Reading University have tested five machines in order to find out whether they would be able to pass for humans in the context of a basic conversation. The program was drafted in 1950 by British mathematician Alan Turing, who affirms that, if a machine may not be distinguished from a human being at this level, it can be considered capable of thinking.
Of five testes robots, only Elba has approached the minimum necessary level, attaining five points beneath the differential limit. However, none of the robots has passed the Turing test, which demanded that the robot should try and cheat on 30% of his human interlocutors in the context of a conversation.

Assisted by a new artificial intelligence system, a robotic helicopter is able to teach itself to fly and perform stunts, by watching and simulating these maneuvers done by other helicopters.
This autonomous helicopter relies on observation and registration rather than on software. Its observation model is an expert in what the Stanford University team calls “apprenticeship learning”, a 4-foot model helicopter flown by radio-control pilot Garret Oku, known to fly amazing acrobatics on any helicopter.
The study conducted by the Stanford University team, made up from professor Andrew Ng and his research graduate students proves that computers can acquire the same skill. Therefore, the artificial intelligence helicopter can do rolls, loops, traveling flips, stall-turns with pirouettes – “ by far the most difficult acrobatic maneuvers flown by any computer-controlled helicopter”, according to the Stanford professor.
The machine is also remarkable through its underlying technology: aftermarket instrumentation such as accelerometers, gyroscopes and magnetometers, since controlling a helicopter is known to be difficult – “ it always wants to just tip over and crash” , says Oku.

The world’s first Android DER 01 was developed by Japanese research group. The Intelligent Robotics Lab, directed by Hiroshi Ishiguro at Osaka University and Kokoro Co., Ltd. have demonstrated the Actroid at Expo 2005 in Aichi Prefecture, Japan. In 2006, Kokoro Co. developed a new DER 2 android. The height of the human body part of DER2 is 165 cm. There are 47 mobile points. DER2 can not only change its expression but also move its hands and feet and twist its body. The “air servosystem” which Kokoro Co. developed originally is used for the actuator. As a result of having an actuator controlled precisely with air pressure via a servosystem, the movement is very fluent and there is very little noise. DER2 realized a slimmer body than that of the former version by using a smaller cylinder. Outwardly DER2 has a more beautiful proportion. Compared to the previous model, DER2 has thinner arms and a wider repertoire of expressions. The smoothness of her movement has also been improved, making it now even more likely for the uninitiated to confuse her with an actual human being. Once programmed, she is able to choreograph her motions and gestures with her voice.
