This paper presents a novel six degrees-of-freedom (DOF) compliant parallel mechanism (CPM) with decoupled output motions, large workspace of ≥6 mm for translations and ≥12° rotations, optimized stiffness, dynamic properties. The working range the motion decoupling capability six-DOF CPM are experimentally verified, mechanical properties shown to be predictable. proposed is synthesized by apply...

There are many patients with inflammatory acne vulgaris who are not compliant or eligible to consume acne medications, such as oral antibiotics or isotretinoin. PubMed and Medline databases were searched for all related articles. All finding were summarized and chronologically presented in the tables. Nonmedical device-based therapies largely improve the treatment of active inflammatory acne vu...

This paper suggests a simple yet efficient experimental method to record the displacement of the shaft in a revolute joint with clearance. Two light and compliant cantilevers have been mounted on the rocker, each being instrumented with two strain gauges which can measure bending. These cantilevers are mounted in an orthogonal fashion, near the axis of the revolute joint, each touching the shaf...

In chapter 3, the compliant mechanism has been designed by topology optimization with rectangular geometry as the basic geometry. In chapter 4, the work has been extended to taper and hexogonal basic geometries. In these studies, for the given input conditions, maximizing the GA and MA have been kept as the objectives. However, in many real life application, we need to obtain a specified output...

This paper investigates the in-hand manipulation capabilities of a compliant, underactuated planar robotic hand by treating the system as a simple, symmetric, 6-bar linkage mechanism with compliant joints. Although underactuated hands are generally not considered to be adept at dexterous tasks, we have found through past work that an underactuated manipulator can control n degrees of freedom wi...

A novel method is proposed in this paper to address the cutting-edge problem of topology optimization of distributed compliant mechanisms, which requires the design to possess both large output displacements and evenly distributed compliance simultaneously. The design is represented by a level-set model that precisely specifies the distinct material regions and their sharp interfaces as well as...
