“…The electric handspike 5 and 8 support and drive the lower arm, and the electric handspike 2 supports and drives the upper arm, which form the hybrid mechanism. The structure plays the parallel mechanism's advantages of stiffness, structural stability, large carrying capacity, high precision, and the serial mechanism's advantages of large operating space, flexible movement [3][4][5].…”

The unique design for a novel 3-DOF hybrid mechanism is proposed in this paper. The 3D modeling of the structure is constructed with Pro/E., kinematics and dynamics simulation by ADAMS software, which can provide a theoretical base for the optimal design and application of the mechanism. This novel 3-DOF hybrid mechanism is suitable for the industrial, agriculture and service applications in which the requirements for simple structure, high stiffness, and large workspace.

“…The virtual pair is a generalized pair. When M and J are adjacent, the virtual pair is a real pair; and when they are not adjacent, the virtual pair is a generalized pair, i.e., a generalized kinematic pair [4,5]. Any transmission between two links is performed by a virtual pair.…”

Deficiencies are existed for currently formulas of mobility calculation for planar mechanism. They are not suitable for planar mechanism with virtual constraints and the number of general constraints equal to 4. To solve the problem, the new concepts of virtual loop, virtual-loop constraint and virtual pair are defined to establish a general f ormula for DOF of planar mechanism; the calculation method for virtual-loop constraint and the mobility of link-group are also given. It is proved that the new formula is correct, general, simple and effective through the mobility analysis of several different kinds of planar mechanisms.

First, the branched-chain of parallel mechanism was Classified according to reciprocal screw theory. Then, the introduction of variable topology mechanism theory, with the characteristics of parallel mechanisms themselves, the definition and basic variable topology means of variable topology parallel mechanism were given. With evolutionary theory, the method to design lower-mobility parallel mechanisms of non-asymmetric was proposed based on variable topology mechanism theory .Taking 3-RPS as ideal mechanism and topology synthesis was carried out, besides 2-RPS mechanism were analyzed. The introduction of variable topology mechanism theory provided a theoretical basis and innovative approaches for the synthesis configuration of Lower-mobility parallel mechanisms of non-asymmetric.
