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.

Scientists have created a robot that has a biologically brain that controls it’s movements. The brain is made of rat neurons and, it’s a remarkable bridge between tech and biology. The project was funded by the UK Engineering and Physical Sciences Research Council.
When the robot is near an object, the signals stimulate the brain by means of electrodes allowing the machine to move around without hitting any other objects. The robot has no additional control from a human or a computer, its sole means of control is from its own brain.
