Performance of Pseudo-Elastic Flexure Hinges in Parallel Robots for Micro-Assembly Tasks
TLDR
In this paper, a pseudo-elastic flexure hinge is used for parallel robots for micro-assembly tasks, and the material used for the flexure hinges is a shape memory alloy permitting angular deflections of ± 30°.About:

Constraint-force-based approach of modelling compliant mechanisms: Principle and application
Haiyang Li,Guangbo Hao +1 more
TL;DR: In this paper, a constraint-force-based (CFB) modeling approach is proposed to model compliant mechanisms with a particular emphasis on modelling complex compliant mechanisms, which can be regarded as an improved free-body diagram (FBD) based modelling approach, and can be extended to a development of the screw-theory-based design approach.

Position-Space-Based Design of a Symmetric Spatial Translational Compliant Mechanism for Micro-/Nano-Manipulation
Haiyang Li,Guangbo Hao +1 more
TL;DR: A position-space-based approach to the design of symmetric compliant mechanisms is presented, which shows that a non-symmetric compliant mechanism can be reconfigured into a symmetrical compliant mechanism by rearranging the compliant modules and adding minimal over-constraints.

Parametric Deflection Approximations for End-Loaded, Large-Deflection Beams in Compliant Mechanisms
Larry L. Howell,Ashok Midha +1 more
TL;DR: In this article, a simple method of approximating the deflection path of end-loaded, large-deflection cantilever beams is presented, where the path coordinates are parameterized in a single parameter called the pseudo-rigid-body angle.

Design for precision : current status and trends
Phj Piet Schellekens,N. Rosielle,H. Vermeulen,Mmpa Marc Vermeulen,Sfcl Serge Wetzels,W. Pril +5 more
TL;DR: In this article, the authors review the status quo in precision engineering and conclude that today's precision engineers put repeatability at the top of their list, and that creativity is more important in keeping the cost down by finding other than locally optimised solutions.
