Image 1: Morphological design of the SCARA type robotized manipulator SCARA robots are ideal for a variety of general-use applications requiring: SCARA robots are articulated cylindrical robots having two parallel rotary joints, and provide compliance in one selected plane. The limited motion of the wrist is advantageous for many types of assembly operations, such as pick-and-place, assembly, and packaging applications. However, the SCARA arm has limited motion at the wrist it can rotate but it cannot tilt. It has the unique ability to pick up industrial components from one location and place/insert them in another, with precision, speed, and smooth motion. SCARA excels in pick and place/insert operations. The 4-axis SCARA was designed as no other robot arm at the time. The first SCARA robot was created as a revolutionary prototype in 1978, in the laboratory of Professor Hiroshi Makino, at Yamanashi University in Japan.
The SCARA robot configuration provides substantial rigidity for the robot in the vertical direction, as well as flexibility in the horizontal plane. The shoulder and elbow joints rotate around the vertical axes.
It has a shoulder and elbow joint, along with a wrist axis and vertical motion. The SCARA acronym stands for Selective Compliance Assembly Robot Arm or Selectively Compliant Articulated Robot Arm or Selective Compliance Articulated Robot Actuator.Ī SCARA robot can perform motions similar to that of a human arm. Since the SCARA robot, with its brilliant simplicity, was introduced in the late 1970s, its accuracy, speed and smooth motion have made it a favourite of manufacturers for a wide range of applications till date.
