Large-Displacement Linear-Motion Mechanisms
thingiverse
The following three designs are compliant linear-motion large-displacement mechanisms. Linear-motion mechanisms are usually constructed using a support structure that guides a shuttle in linear movement. This movement is wanted, and needed in many mechanisms and is generally created using prismatic joints. Prismatic joints are sliding joints that can restrict linear-motion devices to one degree of freedom; but these joints also present challenges including friction, wear, and difficulty in lubrication. Because of these inherent issues, engineers have developed alternatives to prismatic joints in some linear-motion large-displacement mechanisms.
