Bidirectional gear, method, and applications

A method of making a bidirectional gear set including a male bidirectional gear component having an array of addendum teeth and a female bidirectional gear component having an array of dedendum sockets, wherein bidirectional means gear-driven motion in both a translational state and a rotational state, as well as back and forth in both of these states, further wherein in an intermeshed state, neither the male nor the female component can slide relative to the other regardless of whether the male and female components are arranged in a parallel or perpendicular orientation, comprising at least one of:

• creating the female bidirectional gear component having an array of dedendum sockets, wherein each dedendum socket has a full boundary edge around an open end thereof;
• and
• creating the male bidirectional gear component having an array of addendum teeth.
