London: Lonely souls could now look
forward to a unique company, thanks to European scientists who
have unveiled the world`s first robot which is able to display
and detect human emotions.
The humanoid machine, called Nao, which hunches its
shoulders when it feels sad and raises its arms for a hug when
it`s happy, has been designed to mimic the emotional skills of
a one-year-old child, say the scientists.
Nao is able to detect human emotions through
a series of non-verbal "clues", like body-language and facial
expressions, and becomes more adept at reading a person`s mood
through prolonged interaction.
The robot, which is capable of forming bonds
with people who treat it with kindness, uses video cameras to
detect how close a person comes and sensors to work out how
tactile they are, `The Daily Telegraph` reported.
The wiring of the robot`s "brain", designed to mirror
the neural network of the human mind, allows it to remember
its interactions with different people and memorise the faces.
This understanding, along with a set of basic
rules about what is "good" and "bad" for it, allow the robot
to indicate whether it is "sad" or "happy", the scientists
