...Changyu Xue; Kwun-Lon Ting; Jun Wang This paper presents the extension of the N-bar rotatability laws to N-bar chains containing prismatic joints. The extension is based on the principle that a prismatic joint may be regarded as a revolute joint located at infinity in the direction normal...

...Jun Wu; Anurag Purwar; Q. J. Ge In this paper, we present an interactive, visual design approach for the dimensional synthesis of planar 6 R single-loop closed chains for a given rational motion using constraint manifold modification. This approach is implemented in an interactive software tool...

...Ketao Zhang; Yuefa Fang; Hairong Fang; Jian S. Dai This paper presents a three-spherical kinematic chain based parallel mechanism that evolved from an origami fold. The new parallel mechanism with symmetrical structure consists of a base, a platform, and three-spherical six-bar chains as chain-legs...

...Paul Milenkovic For a platform connected to its base through two chains forming a single loop, the instantaneous mobility may be expressed by a set of motion screws that is in the intersection of the sets of motion screws for each of the two chains. A recent work shows that the platform remains...

... of the cables, there always exist inadmissible twists that cannot be produced no matter what the robot velocities are. There are many important applications in which vehicles are used to tow payloads using cables or chains. Conventional oceanographic data collection is largely dependent on towed systems...
