Abstract: A parallel-drive bidirectional deflection platform is introduced. The spatial geometry transformation model is established according to the parallel mechanism characteristics and motion form of the platform. The spatial geometry method is used to solve the positive solution of the parallel mechanism. Two parallel drive motor shafts are known. The angle of the two-way deflection of the platform can be obtained from the corner of the upper driving gear. At the same time, the kinematics simulation of the parallel mechanism is carried out, and the theoretical calculation value and simulation value are compared. The correctness of the kinematics positive solution of the parallel mechanism is verified. The results show that the angle of deflection of the moving platform around the X axis is linear with the angle of its input, and the angle of deflection around the Y axis is related to the two motor inputs.
