Abstract
This paper proposes a position-orientation decoupled parallel mechanism with five degrees of freedom, in which rotational motion of the output link around two axes is controlled by two inputs while translational motion of the target point, the center of rotation of the output link, is controlled by the other three inputs. This mechanism is composed of three connecting chains; one for controlling the position of the target point and two for generating rotational output motion. Conditions of kinematic structures of these chains are discussed and a concrete mechanism is shown. Inverse displacement analysis and Jacobian analysis of this mechanism are carried out to confirm its decoupled feature without encountering the singular point.
