With the rapid development of artificial intelligence and robotics technology, service robots have been widely used in various industries. Service robots are able to autonomously complete a variety of service tasks, such as navigation, handling, cleaning, etc. In order to ensure that the service robots are able to accurately and efficiently complete the task, it is crucial to carry out a comprehensive performance test of the service robots, of which the test of the target localization performance is particularly critical.
In the national standard GB/T38124 “Service Robot Performance Test Methods”, when defining the positioning and navigation performance testing program for service robots, it is clearly stated that “the test equipment can be a visual tracking system, a laser tracker and so on.”
As a representative of large-range (maximum measurement radius of 80 meters), high-precision spatial measurement instrument (15um+6um/m), the performance of the laser tracker fully meets the requirements of the test equipment in the test, and the laser tracker has a highly efficient sampling efficiency (1,000 points/second), but also can be used for a number of test items in the standard, such as “5.1.1 Rated Speed The laser tracker has high sampling efficiency (1000 points/second), and can also test a number of test items such as “5.1.1 Rated Speed”, “5.1.4 Maximum Speed on Slope”, “5.2.2 Navigational Ability” in the standard, which is a very important testing equipment in the performance test of service robots.
The specific application process of GTS laser tracker for testing the target localization performance of service robot is as follows.
Set the rated load and rated speed of the robot, control the robot in a single direction in the test area, starting from the starting point A, according to the set speed and trajectory operation, when the robot stops at the termination point B, then complete a motion test cycle. A laser tracker was used to measure and record the parameters of the robot's stopping position at the termination point B. The parameters of the robot's stopping position at the termination point B were repeatedly measured for 30 times.
Through the accurate measurement of the laser tracker, the performance of the robot positioning algorithm can be comprehensively evaluated, potential problems can be found, and a reliable basis for performance optimization can be provided, which will ultimately improve the service level of the robot and promote the healthy development of the service robot industry.
In the field of robot performance testing, Zhongtu Instruments' laser tracking instruments cover industrial robots, medical robots and service robots, providing complete, efficient and accurate testing solutions for the development of the robot industry and promoting the high-quality development of the robot industry.
