LET (Lamina Emergent Torsion) Array

LET joints use the bending of individual torsion bars to gain bending and translational motion from previously solid sheets of material. This makes it so we can gain large deflections from materials that do not generally bend, such as wood or acrylic.

###Technical Information

The root concepts of this design were published in Mechanism and Machine Theory in November of 2009.
