The newest Japanese robot has a name and humanoid look. It is 1.70 meters high and can
easily walk on a slippery floor. Not only is it able to operate a tool by its right hand,
leaning forward and bow, but also it can balance it as a human does. The robot can not take
over some human professions, such as low-tech construction workers, dustman and guards as
well. It had the ability to perform human functions. The entire production cost will be
reduced and the problem what Japan is rapidly aging and need a larger work force urgently
can be solved.
