The ratio of the axial displacement of the output platform to the radius of rotation can be converted to arcsine to obtain the arc of rotation, and the working range of x‒ and y‒ is approximately a triangle
The ratio of the axial displacement of the output platform to the rotation radius is inversely rotated, and the working range graphs of x‒ and y‒ are approximately triangular
The rotation radian can be obtained by inverse sine transformation of the ratio of the axial displacement and the rotation radius of the output platform. The working range of X ‒ and Y ‒ is approximately triangular
