Opposing constant torque compliant mechanism

This is a compliant mechanism that uses two opposing constant torque 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"
