question?" repeatedly when people
pointed their cameras at it.
"Right now, it can recognize a child
waving to it, but it's not able to

'Not able to comprehend'
Asimo has been in development since
Speaking to the BBC last year, Prof Chris
Melhuish, director of the British Robotics
Laboratory at Bristol University, said that
interaction with humans was the next big
step for robotics.
"The key thing, and it's what we're
working on at the moment, is safe
human-robot interaction," he said.
"That's not just making the robot
compliant, it's making it have advanced
social intelligence. If a robot is handing
you something hot or sharp, for
example, it needs to know whether it has
Honda's head of robotics, Satoshi
Shigemi, told the AP news agency: "Right
