Abstract
The conventional study of the assist robot had difficult that a lot of active movement established safety by complicated structure. I composed it of passive flexibility and aimed at the development of the assist robot which did not need power bigger than the power of the person. I performed a design and production and the performance experiment of the assist chopsticks using the two-way clutch. It functions by attaching a change lever to a two-way clutch. Chopsticks were fixed by this mechanism and were able to catch a thing. However, a sense of incongruity occurred because the difference of the pivot point of a device and chopsticks occurred when I used it. Therefore I produced the assist chopsticks which I improved. I report them.
