Humanoid robots are getting close to reality

Asked a question, Ameca fixes you with sapphire-blue eyes. Does that face contain a hint of a smile? “Yes, I am a robot,” is the reply. Another Ameca, standing nearby in a group of four, stares across inquisitively and tries to join in. “Currently, it’s the worst-ever party guest,” says Will Jackson, Ameca’s creator. “It butts in on every conversation and never shuts up.”

Mr Jackson, boss of Engineered Arts, a small robotics company in Falmouth, south-west England, is trying to fix that problem. Those eyes contain cameras and the Amecas are being trained to recognise faces and decide who is paying attention or making eye contact during conversations. Teaching manners to robots in this way is another step in the long, complicated process of making humanlike machines that can live and work alongside people—and, importantly, do so safely. As Ameca and other robots show, great strides are being made towards this end.
