(26th June, Beijing mean time) According to Daily Mail from UK, recently one robot that can display expressions has been brought to light in Waseda University in Japan. It is said that this humanoid robot called "Kobian" can show all different emotions by using its whole body.

Like we human beings, the robot has mobile eyebrows and eyelids. Researchers even gave it a pair of light pink lips. Also, Kobian has a double jointed neck which helps it to achieve more expressive postures. In order to show sadness, Kobian will close its eyelids, bend forward and put its hand on the forehead at the same time. Showing happiness, Kobian will open its mouth and its eyes wide and extend its arms into the air as a victory salute. As for disgust, it will purse its lips and withdraw one hand just like a delicate woman.

Kobian was developed researchers led by professor Atsuo Takanashi from Waseda University and robots manufacturer TMSUK, which is a company from southern Japan. It made its debut at the IEE conference on computer communications in 2008 as a potential carer for the elderly. 

Originally, Kobian could use its head only to show emotions. Due to the limitation, users said that the robot was hard to interpret. After getting that feedback, researchers improved Kobian, making it express emotions more precisely by moving its whole body.

Besides showing emotions, Kobian is also an outstanding walking robot. It can perceive the surroundings and achieve what it is told to do. Its hands are made of rubber, which gives them softness like people's hands. Developers believe that this expressive robot could be used in nursing.
