About this model

This is a compliant mechanism that uses two opposing constant force mechanisms to create extremely low stiffness. It is printed in a high stiffness configuration, but by engaging the bistable mechanisms in the middle of the device, a low stiffness configuration is enabled. This device has been published as a research paper in the journal of mechanisms and robotics title: "Compliant Mechanisms That Use Static Balancing to Achieve Dramatically Different States of Stiffness" If you are interested. It can be found through these links: 1. 2.
