What Is The Difference Between Parallel Positioners And Stacked Serial Kinematics?
9/27/2021
When faced with a multi-axis motion application, many users stack motion stages, and in fact that is a fine approach for assemblies of just a few axes. But as applications become more complex, so do the equivalent stacks-of-stages, and very real and practical considerations begin to come into play.
