The world's most sophisticated humanoid can grin with satisfaction or sneer in disdain. K-bot has 28 facial expressions and is able to mimic the entire array of human emotions. It was shown in public for the first time yesterday in a remarkable demonstration of cybernetic emotions.
The robot's face is covered with a polymer developed with elasticity comparable to human skin. 'The human face has evolved over millions of years to convey information and even newborn babies are capable of perceiving emotion by looking at a face. This is the first robot to use that leading-edge technology.'
K-bot's face was designed by analyzing the movements of the muscles that control the facial movements of humans.
Scientists intend to further develop robots capable of expressing human emotions as an aid for teachers and doctors. This could become an extremely useful tool for medical therapies at some stage.
