Abstract: The motion of certain spatial mechanisms with up to five links and containing at least one ball-and-socket joint can be visualized and analyzed by considering the intersections of three-dimensional ...

Abstract: Spatial mechanisms with up to five links and containing at least one ball joint can be solved by considering the intersection of the three dimensional surfaces which can be generated by ...

Abstract: The motion of a spatial RRGRR mechanism can be determined by considering the intersection of two tori. In this paper the intersections of two offset skew circular tori are found, thus defining ...

Abstract: General kinematic principles are set down for an algorithmically-simple three-fingered robot-attachment intended to grasp and manipulate objects. After proposing a design for a finger-tip that ...
