What feature distinguishes SCARA robots from other types?

SCARA robots are specifically designed with a distinctive feature called selective compliance, which is primarily observed in their horizontal movements. This means that while they can effectively work in a lateral plane and handle variations in the X and Y axes, they maintain stiffness in the vertical axis. This selective compliance allows SCARA robots to excel in applications that require precision assembly, pick and place tasks, and other operations where horizontal movement is crucial while minimizing the influence of gravitational forces.

Unlike other types of robots, such as Cartesian or articulated robots, SCARA's design enables it to pivot and maneuver with high speed and accuracy in a horizontal plane, making it particularly suited for tasks that require repetitive cycles and precise positioning. This unique mechanical design effectively enhances productivity in environments such as assembly lines and manufacturing, setting SCARA robots apart from other robotic systems that may not emphasize the same level of compliance control in horizontal movement.
