Embodiment 1

[0021] The embodiment of the present invention provides a modeling method based on the design of a goat leg and foot structure, which includes the following steps:

[0022] S1. Randomly select a sturdy goat and place the goat on a flat road. When the goat is walking, use the camera to capture the image of the goat walking;

[0023] S2. Bring up the scene of the goat walking, and do slow motion processing on the scene, carefully observe the goat’s leg and foot changes in a gait cycle, including observing the several walking states and the raising sequence of the goat’s leg in a gait cycle , The lift height of each leg, the relationship between the angle formed at the joint when each leg is lifted and the lift height;

[0024] 1) Determine the walking state: Decompose the walking state of the goat according to the slow motion picture, carefully observe the several walking states in a gait cycle, divide the different walking state pictures into segments, and make each walking state an i...

Embodiment 2

[0030] The difference between this embodiment and the first embodiment is:

[0031] S1. Randomly select a sturdy goat and place the goat on the uphill road. When the goat is walking, use the camera to capture the image of the goat walking;

[0032] S2. Bring up the scene of the goat walking, and do slow motion processing on the scene, carefully observe the goat’s leg and foot changes in a gait cycle, including observing the several walking states and the raising sequence of the goat’s leg in a gait cycle , The lift height of each leg, the relationship between the angle formed at the joint when each leg is lifted and the lift height;

[0033] S3. Integrate the data recorded in step S2 to establish a three-dimensional coordinate system, which includes several walking states in a gait cycle of the goat, the lifting sequence of the goat’s legs, the lifting height of each leg, and each leg The four data of the relationship between the angle formed at the joints and the height of the lift...

Embodiment 3

[0035] The difference between this embodiment and the first and second embodiments is:

[0036] S1. Randomly select a sturdy goat and place the goat on a downhill road. When the goat is walking, use the camera to capture the image of the goat walking;

[0037] S2. Bring up the scene of the goat walking, and do slow motion processing on the scene, carefully observe the goat’s leg and foot changes in a gait cycle, including observing the several walking states and the raising sequence of the goat’s leg in a gait cycle , The lift height of each leg, the relationship between the angle formed at the joint when each leg is lifted and the lift height;

[0038] S3. Integrate the data recorded in step S2 to establish a three-dimensional coordinate system, which includes several walking states in a gait cycle of the goat, the lifting sequence of the goat’s legs, the lifting height of each leg, and each leg The four data of the relationship between the angle formed at the joints and the height...

Abstract

The invention provides a design and modeling method based on a structure imitating goat legs and feet, and belongs to the technical field of walking gaits. The design and modeling method based on thestructure imitating goat legs and feet comprises the following steps: S1, randomly selecting a well-built goat, and placing the goat on a flat road, and capturing a picture about walking of the goat by a camera when the goat is walking; S2, calling up the captured picture about walking of the goat, playing the picture in slow motion and carefully observing change on legs and feet of the goat in agait cycle, establishing a three-dimensional coordinate system and importing four pieces of data to the three-dimensional coordinate system in order to form a three-dimensional walking trajectory of the goat legs and feet, and then obtaining a dynamic model of the structure imitating the goat legs and feet, thereby completely reflecting the walking state and motion rule of the goat, and allowing the structure imitating the goat legs and feet to work in various fields, so as to further improve mechanical equipment in a plurality of fields to some extent.

Description

Technical field [0001] The invention relates to the technical field of walking gait, in particular to a modeling method based on the design of a goat leg and foot structure. Background technique [0002] Walking gait, as a biological feature most commonly used by animals in nature, is the basis for the study of walking walking mechanisms. In recent years, in order to study the walking state and motion laws of animals, many research institutions have conducted studies on many walking animals on the ground. The study of walking state and movement law, goat body is small, limb bones are firm and strong, its supporting feet discretely touch the ground, it can choose the best foot point autonomously, its movement track is a series of isolated points, with active vibration isolation Ability to move at high speeds on uneven and soft ground, with low energy consumption and long-distance walking; its movement gait is agile and brisk, and it can move freely and flexibly on uneven surfaces ...
