The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “With the advancement of industrial technology, a wide variety of automatic devices have been extensively developed for use in l ives and industries. Generally, a robotic arm is an important component of an au tomation device. Although the processing stability of the robotic arm is much hi gher than the manual processing stability, there are still some drawbacks. For e xample, the robotic arm has many joints. Because of the accumulation and transmi ssion of multiple errors, the precision of the robotic arm is not high. For incr easing the precision of the robotic arm, a measuring device is used to calibrate the robotic arm before the robotic arm performs the processing task. At present , the commonly measuring devices include laser interferometers and laser tracker s. Generally, the laser interferometer can measure one axis of errors at a time. For measuring the errors of different items, it is necessary to change the lens groups. Consequently, the operation of the laser interferometer is time-consumi ng. The use of the laser tracker can quickly acquire the detection result at hig h precision. However, the laser tracker is not cost-effective.
