The
Selectively Compliant Articulated Robot Arm (SCARA) is usually a 4-axis
industrial robot. The
kinematic[?] is like a human arm, with the first joint been referred to as the shoulder and the second as the elbow. These 2 joints allow to move in the x- and y-
axis. The third joint is a translation joint and moves along Z. The last joint is Theta and gives a rotation around the z-
axis.
SCARA robots offer the best speed for an affordable price. They are faster than cartesian robots[?] (because they move less mass) or 6-axis robots (because they move less joints and because they are usually stiffer).
They are very common in pick-and-place, assembly and packaging applications.
