Short summary
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.

In order to allow healing from severe fractures cases, a new mechanism is proposed for bone reduction surgery. This hybrid architecture is made of a double triangular planar mechanism and a tripod mechanism. Its kinematic and velocity model are computed while considering the compensation of parasitic motions. Kinematic data obtained from medical image of real case are used for simulations. When compared with the standard Steward mechanism, the present mechanism shows larger workspace.

The optimum design mentioned in the paper was to choose optimum mechanism from the infinite number of mechanism solutions. By imposing constraints, the optimum mechanism solution was straightforwardly identified by the designers. The design data have been obtained and converted into a series of design graphs by the computer program which can be used to synthesize easily four-bar linkages yielding desired straight-line outputs of predetermined position.

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.

In this paper, the preoperative planning algorithm is proposed, which makes the laparoscope provide a reasonable initial visual field. The algorithm offers significant improvements in planning time and quality for robot-assisted laparoscopic surgery. The improved method which combines the preoperative planning algorithm with deep reinforcement learning algorithm is applied to laparoscope arm automatic positioning. The algorithm provides a basis for the robot-assisted laparoscopic surgery.

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. We generate different mechanism property charts by developing mechanism software that enables users to intuitively identify relevant linkage information and select the optimal linkage.

In this study, a compliant wiper mechanism is presented which can be used in land, air, and sea vehicles, particularly the automotive industry. The wiper mechanism is essentially a partially compliant four-bar mechanism. To the best of our knowledge, this is the first compliant wiper mechanism in the literature. After the theoretical calculations, a prototype is manufactured and an experiment is set up. The data obtained from the experimental setup are compared with the theoretical results.

The paper presents a solution region synthesis methodology for RCCC linkages. First, we couple the RC and CC dyads for obtaining all synthesis equations. Then using the solution region theory and Bertini software, all solutions for RCCC linkages can be obtained. The key contribution of this paper is that all solutions of RCCC linkages for four specific poses are obtained. Only one RCCC linkage can be synthesized by the methods published before;

This article proposes a novel monolithic compliant spatial parallel XY stage (SPXYS). An important feature of the SPXYS lies in that it can deliver centimeter travel range and sustain large out-of-plane payload while possessing a compact structure, which makes the SPXYS suitable for some special applications such as Ultra-Violet Nanoimprint Lithography and soft-contact lithography.

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.

This paper investigates a special cube-connected toy that can be reconfigured into several different structures by hand operation. The reconfiguration of the toy is formulated by using an exclusive mathematic modeling through which the physical reconfiguration of the toy can be expressed and manipulated in an algebraic consideration. This research is an example of how mathematics can be applied to study the reconfiguration of mechanisms and mechanical structures.

A new joint mechanism design is presented in this study which has a potential use in robotics, particularly in humanoid robot designs, because of its variable stiffness characteristics, lightweight and remotely-actuated structure. A helical spring inside the mechanism brings compliance which increases the safety. The spring is analyzed with a method proposed in the paper and verified by FEM. The kinematic and the dynamic models are obtained and experimentally validated.

Notch flexure hinges are often used as revolute joints in high-precise compliant mechanisms. 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.

The offset panel technique (OPT) is a method which accommodates for the use of thick materials in origami models and preserves both the range of motion and the kinematics. This work explores new possibilities for origami-based product applications presented by the OPT. Examples are included to illustrate some of the capabilities of the OPT, including the use of various materials in a design and manipulation of panel geometry resulting in increased stiffness and strength in the design.

The paper introduces a comprehensive symbolic matrix representation for characterizing the topology of a metamorphic mechanism using general information concerning links and joints. Operations on the matrices of the adjacent configuration mechanisms are defined to construct an origin matrix and joint variation matrices. The representation of the configurations and evolution of metamorphic Mechanisms provides a foundation for the analysis and synthesis of novel metamorphic mechanisms.
