Mechanical Logic Gates

These are a collection of functionally complete mechanical logic gates that are published in [Song, et al., “Additively Manufacturable Micro-Mechanical Logic Gates.” Nature Communications 10, no. 1 (February 20, 2019): 882.](https://doi.org/10.1038/s41467-019-08678-0)

You can see the operation of the gates in this [video](https://www.youtube.com/watch?v=TUtAdJKKDF0)

NAND and NOR gates are made up of OR, AND, and NOT sub-assemblies.
