南京玉すだれの伸縮機構を用いた超伸縮マジックハンド

抄録

This study proposes a novel reach extender using Nankin Tamasudare, a traditional street performance tool. The device can support elderly people and pregnant women who have difficulty standing up. It can quickly and intuitively reach the maximum distance of 3 m; allow users to pick up objects without standing up. The strong point of this mechanism is the ease of design. The segments of the telescopic mechanism are comprised wood and aluminum. It weighs only 393 g including the gripper, which is operated by a small DC motor that works as a trigger. This gripper acts two roles: catch and release depending on the position in it. Experiments confirm its quick and smooth telescopic motions, and easy manipulation. Moreover, we demonstrate the ability to catch an object in a high place; to slide into gaps and catch an object.
