David McGoran cradles his baby in his arms and looks down into its big, dark eyes. The baby turns its head towards him and blinks, looking contented as it curls a bony white finger around his hand.
But the "baby" is not human. And it looks more like the evil Gollum from "The Lord Of The Rings" movies except in a hemp romper suit with cloth ears than a gurgly infant.
Meet Heart Robot, a flexible, plastic puppet with robotic features that has been programmed to react to sound, touch and nearby movements.
Heart Robot, so called because its red "heart" is visible on the left side of its body and beats at different rates, is certainly getting more attention than its menacing-looking counterpart, iC Hexapod, nearby.
The six-legged creature, which looks like a giant mechanical tarantula, flexes its spiny metal limbs as a miniature camera where the spider's head would be scrutinises the face of a young girl staring at it curiously.
On a television screen next to iC Hexapod, the girl gets a live, robot's eye view of what the machine is seeing, shifting its head in response to her movement and recoiling if she gets too close.
Both Heart Robot and iC Hexapod are "emotibots" -- robots programmed to react to human emotions -- on display this week at the Antenna Gallery at London's Science Museum.
For McGoran and iC Hexapod's inventor, Matt Denton, creating robots that recognise and respond to basic human emotions is a logical step as people's daily lives become increasingly dependent on technology.
