A robot, developed by Japanese researchers, that imitates speech and mannerisms sent through the video-phone makes virtual visits by distant callers possible.

A sensor will transmit the caller's sounds and movements of the head, face and arms to a robot near the recipient, the developers said.
In one demonstration, the robot relayed the voice and movements of a grandchild speaking to a grandfather, saying "I'd like to visit your place... but now my private tutor is here to teach me."
In another demonstration, the same robot, transferring a doctor's presence, asked the same old man: "How are you feeling lately?"
The developers expect the robot to be used in real-life situations, for example in homes to provide company to elderly people living alone.
The robot has been made to look similar to a human but without hair, to appear "as both male and female, as both old and young," the developers said.
