The mathematical model for expressing the spatial relationship is extremely complex and cannot be converted into a mathematical expression of a direct relationship, and many parameters with relatively small influence need to be ignored for practical application. This results in a wide variety of expressions, which greatly affects the accuracy of the detected data, and it can be seen that the calibration of these two parameters is very important.

(3) The locking mechanism of the upper slide rail and the lower slide rail has complex structure, and the processing and assembling cost is increased.
3. The invention patent number of a direct-drive mechanical arm type single-wheel kingpin internal inclination angle and kingpin caster angle calibrating device of Jilin university is as follows: ZL 201510166595.2, the device has the following problems:
