On this special episode, we focus on a small, human-like robot developed by a Japanese scientist. Researchers are studying how it can help people who are socially isolated, connect with others. A German researcher explores whether the robot can be used to benefit elderly people living alone. In Japan, a nursing facility is using it as a conversational companion for people with dementia. And in Italy, a robotics engineer and a psychiatrist have been looking at how it can be used as a communication tool for autistic children.
