Explain the importance of calculating a robot’s ability to extend its arm

robot's importance

Explanation:

An industrial robot is equipped with many metrological or measurable properties that directly influence the efficiency of the robot during its performance. Repetitiveness and accuracy are the main measurable features. In general, a robot's repetitiveness might be defined as its ability to perform the same task repeatedly. On the other hand, precision is the difference (i.e. the mistake) between the requested task and the achieved task. Its concepts are often confused in robotics when it comes to repeatability and accuracy.Therefore, repeatability is always doing the same thing, while accuracy always reaches your target.

i think the answer is b.
