Where future robots should go and should not go

Where future robots should go and should not go and what is an adequate style of collaboration between human and robots? These questions are really interesting for discussing the future direction of robot, especially from the design point of view. While it is really hard to find a general answer for these questions, we try to provide our answers, particularly focusing on manipulation area, by reviewing our former works and exploring a success example of robot business. Our eventual message is that we should cut the function of “manipulation of object within hand” as an end-effector and focus on a hand with single purpose rather than universal hand.
