Abstract
An offset rotary joint unit equipped with a rotation correction mechanism, in which a bending motion can be executed in a two-dimensional plane only by virtue of a rotary mechanism and which can support a high-load weight and is applicable for two-arm mechanisms such as nursing assistant robots. One offset rotary joint unitis composed of a first arm, a rotation correction armrotationally driven around the axial line of the first arm, and a second armrotationally driven around an axial line obliquely intersecting with the rotation correction arm. A rotation correction joint mechanismlinking the first armand the rotation correction armand an offset rotary joint mechanismlinking the rotation correction armand the second armare driven by a single motor, and the rotation correction joint mechanismrotates synchronously and in the reverse direction, following the rotation of the offset rotary joint mechanism, thereby allowing the second armto execute a bending motion in a two-dimensional plane with respect to the first armonly by virtue of rotary mechanisms.
