Many linkage mechanisms can be broken into components consisting of planar two-revolute (2R) and three-revolute (3R) serial chains, such as the five-, six-, and eight-bar mechanisms. In this study, a new method for the dimensional synthesis of the planar 3R serial chain for motion generation based on CGA is presented. The proposed method provides a new meaning for the motion synthesis of planar serial chains and can be applied to many other types of planar mechanisms.

Aiming at the complex control system of a quadruped robot, a leg structure of a quadruped robot was designed based on mechanism synthesis. The innovativeness of this robot is that it can achieve a special gait driven only by a single motor. Simulation and experimental analysis prove that the mechanism is reasonable, reliable and can meet the requirements of linear walking and climbing. The conclusions of this research will be useful for application in field of single actuated quadruped robots.

A systematic methodology for the type synthesis of a compliant parallel mechanism (CPM) with a suitable constrained branch is introduced. The whole type synthesis principle is built upon the rigid-body-replacement method and the freedom and constraint topology approaches. A series of 2R1T motion CPMs with a suitable constraint branch are proposed. These synthesized compliant mechanisms have potential applications to posture adjustments for the space optical load in the aerospace field.

A method is developed for planar four-bar linkages to cope with the mixed synthesis of motion and path-generation problems. The developed method selects an optimal combination by using the conic filtering algorithm, which is based on the similar characteristics of the value and direction between the conic and coupler curves in a certain neighborhood. The selected combination is substituted into an equation system of motion synthesis to solve the parameters of the planar four-bar linkages.

The temperature distribution of a machine tool spindle is affected by its air gap. The more serious the air gap eccentricity is, the more uneven the temperature field of the spindle is. In the process of machine tool processing, the instability of the spindle temperature field leads to the decline of parts processing quality and unqualified products, which not only wastes materials, but also affects the processing process.

Thickness-utilizing deployable hard stops (ThUDS) block the motion of a mechanism at a desired position. Designed to reside within the thickness of a design, they can be planar or spatial in nature. Various analyses and design techniques were developed and demonstrated using physical prototypes. ThUDS are able to successfully constrain motion, are able to carry loads, and are useable in various folding applications, including origami-based engineering.

This paper proposes a novel type of bistable mechanism with linear negative stiffness and large in-plane lateral stiffness. Then, by connecting the negative-stiffness mechanism in parallel with a positive-stiffness mechanism, a novel quasi-zero stiffness compliant mechanism is developed. It has better axial guidance capability and in-plane lateral anti-interference capability compare to the conventional mechanism. Such mechanism can be used as constant-force mechanism and vibration isolator.

Valve mechanisms are needed to control the intake and exhaust processes of today's engines. The valves in this valve mechanism are actuated by machine parts called camshafts. The cams on the camshaft have specially designed profiles for the movement of the valves. Different cam profiles must be created for each engine size and characteristic. In this study, the camshaft design parameters were dimensioned and thus a new design approach that can be used in all cam designs was presented.

We sometimes meet the problem of linkage synthesis for 4 specified orientations. For example, we need to design an automobile seat based on spherical 4R linkage to move the driver to the ground. According to the traditional Burmester theory, most of the linkage solutions have motion defects, which lead to low computational efficiency. In this paper, a program package was developed under Matlab, which can quickly locate the feasible linkage solution under the guidance of solutions map.

Origami is a powerful and elegant tool that can be used by engineers to overcome challenges. The shape of the origami is essential to this. We categorize the shapes (fold states) of origami into seven classifications. This categorization method is supported by analyzing 69 origami-based devices for correlations between the classification and the types of functions they perform. These correlations can be used to design and select origami fold states.

We present a solution-region-based synthesis approach for selecting optimal four-bar linkages with a Ball-Burmester point. We discuss both general and special cases of the Burmester point that coincide with the Ball point at the pole of the inflection circle.

It is proposed a novel design method for large stroke XY compliant mechanisms. An important feature of the design lies in it restricts the parasitic rotation by reducing the moment of force instead of increasing the rotational stiffness widely utilized in the literature. It is presented a millimeter stroke XY nanomanipulator with the proposed design based redundant constraint in a case study. The proposed design provides an alternative to reduce the parasitic rotation of XY compliant mechanism.

Therefore, this paper presents design equations for the calculation of the rotational stiffness, maximal angular elastic deflection and rotational precision of various notch flexure hinges in dependence of the hinge parameters and the load. Four flexure hinge contours are investigated, the semi-circular, the corner-filleted, the elliptical, and the recently introduced bi-quadratic polynomial contour.

We propose a novel mechanism synthesis approach for a 1-degree-of-freedom (DOF) rehabilitation robot, based on chord angle descriptor (CAD) and error tolerance expansion, to generate a pool of mechanism solutions from which mathematically and practically optimal solutions can be selected. A design example of a 1-DOF rehabilitation robot for upper-limb training is provided to demonstrate the efficacy of our novel approach.
