As an important part supporting the weight of aircraft and absorbing the impact energy

landing gear is faced with the special requirements of narrow assembly space and high assembly precision in the process of assembly and test. Therefore

it is urgent to develop a flexible assembly platform with movable and multi-degree of freedom adjustment functions. Through analysis of gear assembly requirements

the 6-DOF assembly robot was designed based on Mecanum wheel omni-directional mobile and 3–RPS parallel mechanism. The structure and control method were introduced in detail. By analyzing robot kinematics characteristics

a kinematics model was obtained

and the kinematic parameters and accuracy are analyzed. Finally

through the landing gear assembly test

the function and performance of the robot can meet the operational requirements.
