The Two definitions are:
1.Selective Compliance Assembly Robot Arm: It was the original definition and is still probably the most common.
2.Selective Compliance Articulated Robot Arm: It came into use later as SCARAs have been applied to other tasks which do not involve assembly.
In robotics, compliance means that a robot has flexibility of its joints (or sometimes in its mechanical structure). If you will push a compliant robot, it will give way under your touch. It won’t push back ahead or hold steady. SCARA robots are compliant in the X-Y axis but rigid in the Z-axis. It gives them some flexibility which is particularly useful for assembly applications which require compliance — e.g. inserting a peg in a hole.
Uses:
Rigidity: Due to their selective compliance, they are less rigid than Cartesian or gantry robots. However, they are more rigid than both 6-axis and Delta robots due to their rigid Z-axis. This makes them a kind of “halfway house” between Cartesian and 6-axis robots.
Speed: They are very well suited to high-speed assembly applications and are generally faster than 6-axis robots. As a result, it is much more likely to see them being used for pick-and-place but however, they are not as fast as Delta robots which are the top choice for high-speed pick-and-place.
Axes: One of the clearest distinctions between SCARAs and 6-axis robots is that they have fewer Degrees-of-Freedom just like most Delta robots, they have only 4 axes.
Payload: The payload is generally quite low. The models in Robot Library can lift between 0.5–20 kg. This is much less than 6-axis robots which can lift between 1–1700 kg which is more than Delta robots which can lift between 0.3–8 kg.
Repeatability: Assembly tasks require quite a high degree of precision which means that they generally have better repeatability than other types of robot. The robots with the best repeatability are all SCARAs and it’s not uncommon to see them with a repeatability of just 0.01 mm.

Small Assembly: High-speed assembly tasks, such as those in the electronics industry are very common for SCARA robots. Their selective compliance means that they can perform insertions more easily than other types of robots without having to use complex programming.
Laser Engraving: The high precision of SCARA means that they are also very well suited to laser engraving and drawing tasks. Over the last few years, several end effectors have come onto the markets which allow you to add
laser engraving capabilities to any small robot.
3D Printing: Another task is 3D printing. We’ve already seen a lot of applications where 6-axis robots are making it possible to print much bigger objects with 3D printing technologies. SCARAs are well suited to these new applications on the smaller end of the scale.
