Before a robot is put into operation, what should be done to the arm?

The correct action to take before putting a robot arm into operation is to calibrate it. Calibration involves adjusting the robot's arm to ensure it operates accurately and performs its tasks within specified tolerances. This process is critical as it aligns the physical movements of the robot with the programmed instructions, enabling it to carry out tasks with precision. It often includes setting the limits of movement, ensuring sensors are correctly responding, and confirming that the robot can reach all intended areas without interference or errors.

Jogging, while it may help in testing the robot's movement range and functionality, is more of a maintenance routine than a preparatory step. Covering the arm may protect it, but it does not prepare it for operation. Repairing an arm would only be necessary if there were issues or damage present, which should already be addressed before preparation for operation. Thus, calibration stands out as a fundamental step in readying the robot for effective and accurate use.
