What does SCARA stand for?

• A. Selective Compliance Assembly Robotic Arm
• B. Selectively Compliant Assembly Robot Arm
• C. Selective Coordination and Robotic Arm
• D. Systematic Compliance and Robotic Assembly

Answer: (B)

SCARA stands for Selective Compliance Assembly Robot Arm. The key idea is that the design is selective about how flexible it is: it is compliant in the plane of motion so it can accommodate small misalignments during assembly, guiding parts together smoothly, while remaining stiff in directions where precision is critical (such as vertical positioning). This combination lets SCARA robots move quickly in the horizontal plane and perform accurate placements, which is ideal for high-speed assembly tasks. The wording in literature may vary slightly (for example, “Selective Compliance Assembly Robot Arm” is the most common form), but the concept remains the same: selective flexibility paired with solid rigidity for reliable, fast assembly.
