This article gives an overview of the different systems that are out there, what are some of the legal obstacles, and how various countries are investing in the technology. From the article: "The Japanese government has allocated about $23M USD to the core technology market in an effort to develop products for its aging population. Toyota, for example, is focusing on home living assistance robots that will allow those with limited mobility the opportunity to live at home. While Japan might have the largest market in the world of 65+ citizens (over 30 million as of 2014), South Korea is estimated to be allocating nearly $6B USD to their own robotics research. The Koreans are taking a different approach, using robots for mundane tasks of delivering food, allowing humans to provide care."
