Kinematic Coupling

Imagine two rigid objects with specially shaped surfaces that allow them to fit together in only one specific position and orientation. This type of connection is known as a kinematic coupling. It relies solely on the geometry of the surfaces to constrain movement, without requiring any additional locking mechanisms.

Our baseplate and toolchanger use this mechanism.

• Notes from this site: https://practicalprecision.com/kinematic-constraint/

There are also pseudo kinematic couplings, and surely many other kinds you can learn about.
