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.<\/span><\/p>\n

The\u00a0SCARA\u00a0acronym stands for\u00a0Selective Compliance Assembly Robot Arm or\u00a0Selectively Compliant\u00a0Articulated Robot Arm<\/span> or Selective Compliance Articulated Robot Actuator.<\/span><\/p>\n

A SCARA robot can perform motions similar to that of a human arm. It has a shoulder and elbow joint, along with a wrist axis and vertical motion. The shoulder and elbow joints rotate around the vertical axes. The SCARA robot configuration provides substantial rigidity for the robot in the vertical direction, as well as flexibility in the horizontal plane. <\/span><\/p>\n

SCARA<\/span><\/h2>\n

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 4-axis SCARA was designed as no other robot arm at the time. <\/span><\/p>\n

SCARA excels in pick and place\/insert operations. 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.<\/span><\/p>\n

However, the SCARA arm has limited motion at the wrist; it can rotate but it cannot tilt. The limited motion of the wrist is advantageous for many types of assembly operations, such as pick-and-place, assembly, and packaging applications.<\/span><\/p>\n

SCARA robots are articulated cylindrical robots having two parallel rotary joints, and provide compliance in one selected plane.<\/span><\/p>\n

SCARA \u00a0robots are ideal for a variety of general-use applications \u00a0requiring:<\/strong><\/h4>\n
    \n
  • Fast, repeatable and articulate point-to-point movements<\/span><\/li>\n
  • Consistent reliable performance,\u00a0repetitive accuracy\u00a0<\/span>and high precision<\/span><\/li>\n
  • Handling \u00a0of heavy workloads and performing in a harsh environment<\/span><\/li>\n
  • Withstanding without problems of unexpected stress and collisions<\/span><\/li>\n
  • Operations involving tight tolerances, such as putting a shaft into a hole<\/span><\/li>\n<\/ul>\n

    The three major applications areas of SCARA robots are assembly, pick and place, and palletization<\/strong>.<\/span><\/p>\n

    Another important area is in applications requiring constant acceleration through circular motions, like dispensing and in-place gasket forming.<\/span><\/p>\n

        Palletizing is a demanding application of stacking boxes, bags, cases, bottles, and cartons onto pallets as the last step in the assembly line before being loaded onto a shipping truck. <\/span><\/p>\n

        SCARA robots<\/span>\u00a0are designed for high-speed, heavy payload, and long-reach palletizing applications.<\/span><\/p>\n
