Schoenflies (or Schönflies) displacement (or motion) named after
Arthur Moritz Schoenflies
Arthur Moritz Schoenflies (; 17 April 1853 – 27 May 1928), sometimes written as Schönflies, was a German mathematician, known for his contributions to the application of group theory to crystallography, and for work in topology.

is a rigid body motion consisting of linear motion in three dimensional space plus one orientation around an axis with fixed direction. 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.
Because the
SCARA manipulator was one of the first manipulators providing similar motion, this is often referred to as SCARA-type motion. Today, many
