... in the literature, very few 1-DOF multi-mode PMs have been proposed. This paper deals with the type synthesis of a novel class of 1-DOF multi-mode PMs, which have one 1-DOF translation mode and at least one 1-DOF planar motion mode, using a construction method by leveraging symmetry of mechanisms and merging two...

...Wuxing Pan; Ruiqin Li In type synthesis of mechanisms, isomorphic identification of kinematic chains is a key issue, which has been studied for many years. In this paper, a new topological invariant, a character array of edge is constructed based on a novel model called an equivalent mechanical...

... legged mobile lander type synthesis truss-mechanism transformation parallel mechanism multi-loop chain In the exoplanet exploration project, the mission mainly includes Circling , Landing , Return three missions and Base Construction in the future [ 1 ]. So far, the Circling and Landing...

.... In such problems, a type synthesis approach makes the complex problem easier by using a divide and conquer approach, where building blocks are utilized to create certain motions and forces. Numerous building block methods exist for rigid link mechanisms. However, they fail to describe the intricate behavior...

.... Assoc. Editor: J. M. Selig. 21 06 2014 24 10 2014 06 04 2015 Parallel manipulators (PMs) with multiple operation modes are novel reconfigurable PMs, which use less number of actuators and can be reconfigured without disassembly. This paper deals with the type synthesis of 2-DOF...

... the guidance of a graphical type synthesis method. This PKM is composed of four identical arms and a single platform and has high rotational capability. The single-platform structure used in the proposed PKM can reduce structural complexity, increase dynamic response. In addition, the composite parallelogram...

...) of a parallelogram generates circular translation. This paper deals with the type synthesis of single-DOF single-loop overconstrained mechanisms composed of six R and/or H (helical) joints (6R, 4R2H, 2R4H, and 6H mechanisms in short) for circular translation. These mechanisms provide potential alternatives to planar...

...) planar RCM mechanism type synthesis method is proposed. The basic principle is to construct virtual double parallelogram structure at any instant during the mechanism movements. Different with the existing ones, both of the actuated joints of the obtained RCM mechanism are revolute joints. Combining...

... PMs proposed so far are very limited. The methods for the type synthesis of multimode PMs have their own merits but suffer from certain limitations. The method in Ref. [ 20 ] suffers from the difficulties in finding directly the intersection of high-dimensional manifolds. The method in Ref. [ 21...
