Step 6A.3: Add a Transforming Mechanism

Summary of this Step

A Transforming Mechanism is the term we use for the Parts we add to the Motion-Part so that we can locate the Power-Source* more conveniently in the machine.

A Transforming Mechanism introduces the concept of Inverse-Kinematics.

*Power Source - the device or element that provides the power to the kinematic-chain. In this case, the Power Source will be the 2D-Cam.

Dyad is a kinematic term for the connection of:

Two Parts

Three Joints

The Dyad is identified by its combinations of Pin-Joints, Slide-Joints and Ball-Joints.

However, Dyads use different terms for these Joints.

Pin-Joint has the term Revolute-Joint. It has the letter R

Slide-Joint has the term Prismatic-Joint. It has the letter P

Ball-Joint has the term Spherical-Joint. It has the letter S

E.g.: An R-R-R Dyad is a dyad that joint two Parts with three Revolute-Joints.

Note 2: In MechDesigner, there are 5 Planar Dyads, and 2 Spatial Dyads.
