Optionally, a possible preset mapping method is: here, the right arm is taken as an example for illustration, as shown in Figure 1C, with the joint of the arm as the center of the circle, the vertical position of the action generation module is placed with the horizontal plane The vertical line is used as the y-axis, and the horizontal line passing through the center of the circle is used as the x-axis, abstracting the surface where the action generation module is located as a plane, and the xoy plane coincides with the abstract plane.
