If you can get to South Ken., check out David McGoran's Heart Robot, which just wants to be hugged, cuddled and stroked. From the Beeb:
It has a beating heart which rises when the body is shaken, but slows down when treated calmly. In addition, Heart's eyes flutter in response to touch. ... [McGoran] believes there could be major implications for social care, with research already taking place into giving elderly care homes robots that express emotions.
The way it flings its palm out to shake hands is cute and quite startling. Question: why sheep?
