Japan has a serious focus on robots in the home and care for the elderly. This post is an example::
Gearlog : RI-MAN Humanoid Robot Cares for the Elderly: "Now, there's the 5-foot RI-MAN Humanoid Robot, created by the Japanese research team Riken, that can see, hear, smell, and even carry human beings--particularly those that are elderly. RI-MAN is equipped with sensors that show it a body's weight and position. So, I guess this takes the 'I've fallen and I can't get up' idea to new levels.
So why a robot that can carry the elderly? Apparently, Japan is expecting a major increase in elderly care due to people living longer, so the RI-MAN would aid in carrying a person to the bathroom, to bed, or wherever they need to go."
