This paper concerns the issue of mechanism design of a simplified 6-DOF 6-RUS parallel manipulator. The design of robotic mechanisms, especially for 6-DOF parallel manipulators, is an important and challenging problem in the field of robotics. This paper presents a design method for robotic mechanisms, which is based on the physical model of the solution space. The physical model of the solution space, which can transfer a multi-dimensional problem to a two or three-dimensional one, is a useful tool to obtain all kinds of performance atlases. In this paper, the physical model of the solution space for spatial 6-RUS (R stands for revolute joint, U universal joint and S spherical joint) parallel manipulators is established. The atlases of performances, such as workspace and global conditioning index, are plotted in the physical model of the solution space. The atlases are useful for the mechanism design of the 6-RUS parallel manipulators. The technique used in this paper can be applied to the design of other robots.

Origami structures morph between 2D and 3D conformations along predetermined fold lines that efficiently program the form of the structure and show potential for many engineering applications. However, the enormity of the design space and the complex relationship between origami-based geometries and engineering metrics place a severe limitation on design strategies based on intuition. The presented work proposes a systematic design method using topology optimization to distribute foldline properties within a reference crease pattern, adding or removing folds through optimization, for a mechanism design. Following the work of Schenk and Guest, foldable structures are modeled as pin-joint truss structures with additional constraints on fold, or dihedral, angles. The performance of a designed origami mechanism is evaluated in 3D by applying prescribed forces and finding displacements at set locations. The integration of the concept of origami in mechanism design thus allows for the description of designs in 2D and performance in 3D. Numerical examples indicate that origami mechanisms with desired deformations can be obtained using the proposed method. A constraint on the number of foldlines is used to simplify a design.

The paper provides a simple, fast and practical method which follows the rule of maximizing minimum transmission angle to design crank-rocker mechanism. The method which uses the optimal design method is based on the research of papers[1]~[3] . Through the analysis and calculation, the paper gives the conclusion and drawing of k-φ-d-(γmin) max and k-d-a-b.

In this paper, the auction of divisible goods is investigated and a mechanism design method for optimal auction of divisible goods is presented. First, the definitions of feasible allocations and divisible goods auctions are given based on several important assumptions of divisible goods auction. Second, an optimal auction mechanism of divisible goods is designed, and a method of how to use the uniform price auction to implement the optimal auctions is discussed under the background of allocating the total permitted pollution discharge capacity (TPPDC). Lastly, this method is applied to the environmental planning of Wuhan City Circle in Hubei Province, China.

The measurement of pose and position is the key technology for Explosive Ordnance Disposal (EOD) robots intelligence level. This paper presents a mechanism which using a laser distance sensor (LDS) to measure a cylinder-like objects pose and position. The mechanisms structure, constitution and measure principle are described in details. Calculation method and formulas are also given. Only two points position is needed to measure an ammunitions pose and position synchronously by the given mechanism and algorithm. Satisfied precision could be achieved by applying the mechanism and stereo vision to Explosive Ordnance Disposal robot to recognize ammunitions pose and position. The measure data can be used to guide the robot arms route planning and autonomously movement.

The paper deals with the structural synthesis and kinematic analysis of bi-mobile mechanisms used in robotics and other industrial equipment when a suitable curve is necessary to be described in a manufacturing process. The design method is illustrated step by step for a bi-mobile mechanism design. The parameters obtained through the analysis of the inverse model may be used for the system command and control.
