Abstract

The invention relates to a method and system for determining the degree of freedom of the spine of a robot mouse. The method comprises: according to the video of the rat to be tested moving under the X-ray, 33 joint points of the vertebrae of the rat to be tested are marked to obtain the relationship between the position and time of each joint point; The absolute value of the difference between the angle change value and the angle change value of each joint point at adjacent moments; obtain the first constraint and the second constraint; according to the joint point of the first constraint and the second constraint The absolute value of the angle change value of the adjacent joint points and the difference between the angle change values ​​of each joint point at adjacent moments is screened to determine the set of reserved joint points; respectively, the set of retained joint points is extracted by principal component analysis , determine the extracted joint point set; determine the degree of freedom of the spine of the robotic mouse according to the extracted joint point set. The invention can accurately determine the degree of freedom of the spine of the robot mouse, thereby improving the bionic precision of the robot mouse.

Description

technical field [0001] The invention relates to the field of bionic mechanism design, in particular to a method and system for determining the degree of freedom of the spine of a robotic mouse. Background technique [0002] In the existing bionic mechanism design, more attention is paid to the large biological joints with obvious configuration and easy to analyze, such as the main joints of the legs such as hip joints, knee joints, and ankle joints. The number of main joints in the leg is small, the motion analysis is simple, and the degrees of freedom are easy to extract. In the design of bionic mechanism, the selection and design of degrees of freedom are very important, and a reasonable design method of degrees of freedom can provide guidance for the design of bionic mechanisms. [0003] Among them, for the degree of freedom design of the mouse legs and feet, reference can be made to other bionic quadruped robots. However, the method for designing the degree of freedom ...
