Schoenflies displacement explained

Schoenflies (or Schönflies) displacement (or motion) named after Arthur Moritz Schoenflies is a rigid body motion consisting of linear motion in three dimensional space plus one orientation around an axis with fixed direction.^[1] In robotic manipulation this is a common motion as many pick and place operations require moving an object from one plane and placing it with a different orientation onto another parallel plane (e.g., placement of components on a circuit board). These robots are commonly called Schoenflies-motion generators.^[2]

Because the SCARA manipulator was one of the first manipulators providing similar motion, this is often referred to as SCARA-type motion.^[3] Today, many robotic manipulators, including some with parallel kinematic architecture, are used in industry for applications ranging from the manufacture of electronics to food processing and packaging industry.^{[4] [5] [6]}
