Using Rigid-Body Mechanism Topologies to Design Path Generating Compliant Mechanisms
February 2016

This paper shows how the design of path generating compliant mechanisms can be improved in a number of ways.

Three-Position Synthesis of Origami-Evolved, Spherically Constrained Spatial Revolute–Revolute Chains
February 2016

Based on the Miura-ori origami pattern a mechanism family with naturally given slim shape may be evolved. Kinematic synthesis allows task-specific design, which is demonstrated in a car door guidance task. The result is a spatial car door guidance linkage that satisfies particularly given space requirements of the task.

Design and Development of a High-Speed and High-Rotation Robot With Four Identical Arms and a Single Platform
November 2015

A novel parallel kinematic mechanism (PKM) with Schönflies motion has been proposed under 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 Role of the Orthogonal Helicoid in the Generation of the Tooth Flanks of Involute-Gear Pairs With Skew Axes
February 2015

Camus’s theorem provides a universal approach to the synthesis of conjugate profiles when the relative motion program is assigned through the relative centrodes (pitch curves). The main point is to choose the most convenient auxiliary curve, in order to trace the pair of conjugate tooth profiles as trajectories of a point or envelope of a second curve attached to this auxiliary curve. Thus, Camus’ concept of auxiliary surface (AS) is extended to the case of involute gears with skew axes with the aim to provide a unified theory to synthesize any type of gears.

Design of Planar Multi-Degree-of-Freedom Morphing Mechanisms
February 2015

Morphing mechanisms represent a class of machines that can change their shapes to perform critical functions in a variety of fields. This paper considers morphing mechanisms composed of rigid links that can be designed to approximate different shapes defined by planar curves. Such mechanisms may have applications in morphing aircraft wings that increase flight efficiency and morphing dies for manufacturing complex plastic products faster and less expensively than is currently possible.
