When robot Nao laughs, he does so with his whole body: slapping his knees, shaking his head. But the adorable android, made by SoftBank Robotics, is not merely good at expressing mirth; he can correctly identify as much as 65 percent of happy laughter outbursts in humans, according to a study presented in 2015 at a nonverbal language workshop in the Netherlands. Once robots like Nao master human laughter, they will make far more likable and realistic companions. Nao's creators and other scientists are studying the minutiae of human laughter--acoustics, breath, body movements and vibrations--to translate them into algorithms that robots and avatars can learn. And that includes learning how to be funny. In 2016 researchers in South Korea and Singapore showed that Nao is already quite good at telling jokes.

Can you recognise when someone is unwell just by studying their face? Understanding expressions can help doctors improve their diagnoses, but it's a difficult skill to practise. So a group of engineers have made a tool for training clinicians: a robot that can express pain. Many doctors already use robotic patient simulators in their training to practise procedures and test their diagnostic abilities. "These robots can bleed, breathe and react to medication," says Laurel Riek at the University of California, San Diego.

Demonstration materials can take the research and industry presentations, project demonstrations, (Path planning, animation / camera control, tactical / strategic form of a recorded demonstration session, an executable version interactive poster sessions, and product exhibits.
