Problems solved by technology
The existing industrial robot pose testing device is mainly a laser tracker. Although it has the advantages of high measurement accuracy and fast speed, this instrument also has limitations on the site and space required for measurement, which is not conducive to the on-site operation and measurement of industrial robots. , and the instrument cost is higher and the operation is more complicated
Moreover, the existing traditional low-cost industrial robot reliability test devices are all tested under the condition of no load, which cannot be called a real industrial robot reliability test.
In the case of a load, it does not conform to the test results of the pose accuracy test method, and the test results of such a traditional test method cannot accurately characterize the working accuracy of industrial robots.
