Autonomous robots are able to move and decide by themselves.At a simple level,these can include robot vacuum cleaners that"decide"what to react to human behaviors without human intervention.

The University of the West of England\'s David McGoran takes his Heart Robot on a touchy feely tour,allowing it to come face to face with a spider-like robot built by Matt Denton of Micromagic Systems.Both robots are being displayed at the London Science Museum until July 3Ist.

The heart robot that"enjoys"being hugged and stroked could be among the first robots to signify a new era ofemotional machines"used for medical treatment and enjoyment,according to one of its inventors.

It has a beating heart which rises when the body is shaken,but slows down when treated calmly.In addition,Hearts eyes flutter in response to touch

David McGoran.of the University of the West of England,predicts the parL-puppet,part-ma-chine creation he helped develop is an example of how robots will increasingly adopt human characteristics.Right now we\'re seeing the first implementations in toys,he told BBC News."There are little robotic dinosaurs.There\'s a new robotic toy from the film Wall-E that\'s coming out,and that\'s a very expressive robot."Nevertheless he believes there could be major implications for social care，with research already taking place into giving elderly care homes robots that express emotions.

"This raises really interesting social and ethical questions,"said Mr.McGoran.He added that there could be many benefits,particularly for people taking medical treatment."If scientists can put this natural interface into robots then it would be much easier for us to relate to robots".

The Heart Robot is on display alongs ide a face-tracking insect-like robot.The"ic Hexapod"by Micromagic Systems has been programmed to recognize human facial features and follow people as they move around It tracks human faces an takes photos.Like the Heart Robot,it is billed as example of the increasingly sophisticated ways in which machines are able to recognize and mimic human.
