SCARA is an
acronym for
Selectively Compliant Articulated Robot Arm. A SCARA has
axes of motion analogous to a person's
shoulder and
elbow, which provide horizontal motion, and perhaps another axis at the
wrist, to provide rotation. Vertical motion may be provided by another axis either in the wrist or in the robot's base.
SCARAs are used in manufacturing assembly and physical therapy, among other places.
