Problems solved by technology

[0002] In specific occasions such as research institutes and factories, there are many experimental instruments and products (such as automobiles) that need to be calibrated. These objects to be calibrated include some objects with high quality and high requirements for calibration accuracy. The calibration of some objects to be calibrated has the problem of laborious handling and difficulty in meeting the calibration accuracy requirements. At the same time, unreasonable calibration may have adverse effects on the use of experimental equipment and products.

[0003] In order to adapt to the industrial needs of the new era and solve the above-mentioned problems, a large number of docking installation platforms with six degrees of freedom in space have emerged, and they can all realize docking installations with six degrees of freedom in space, such as the Stewart mechanism proposed by D.Stewart and Eric.Gough. Gough mechanism and other 6‐DOF platforms, but there are many shortcomings, such as complex mechanism, difficult processing and assembly, poor algorithm effect (such as singular point, adjusting pose coupling, etc.), insufficient travel, and difficult trajectory planning Wait
