Test method and system of animal foot-face contact counter force

Abstract

The invention relates to a testing method and a system for the surface-contact counterforce of the foot and surface of an animal. The invention belongs to the technology of force measuring. The method includes the following steps: confirming a sensor, the rate capacity and resolving capability of which meet requirements; demarcating the sensor; designing the arrangement form of a force measuring array; designing an animal movement channel formed by the sensor; conducting the animal to pass through a force measuring sensor channel; using a video image and the counterforce data collected in a sensor system for screening the data of the whole sole of the animal acted on the sensor as the effective data. The system includes a sensor array bracket, the force measuring sensor array arranged on the sensor array bracket; the strain signal of the sensor on the array is connected on a computer by a conditioning amplifier. The system also includes a high speed vidicon which realizes synchronous collection with the force measuring data. The system can simultaneously measure the information like the contact counterforce, the contact time and the moving action between each sole of a large gecko and a spider and an attachment surface when the large gecko and the spider move on a horizontal plane, on a vertical plane and on a ceiling.

Description

technical field [0001] The invention relates to the field of testing of animal kinematics and robot bionics. In particular, it relates to geckos, spiders, beetles and other adhesive animals (referring to animals whose soles can generate adhesive force so that they can move on various surfaces in a 3-dimensional space). Test system for force and real-time image acquisition. And can be used to determine the motion performance of the robot. Background technique [0002] Movement is the basic characteristic of animals and the basis of animal predation, escape, reproduction, migration and other behaviors. The locomotor behavior of animals is the result of the interaction between the animal and the environment under the action of internal force (muscle force). The pods living on the ground realize the driving, stabilizing, maneuvering and other movement behaviors through the force interaction between the soles of the feet and the ground (including walls, ceilings and other surf...

AI Technical Summary

Problems solved by technology

It adopts the semiconductor strain test technology, the stability needs to be improved, and the force measurement range cannot adapt to the measurement of the reaction force of larger animals such as geckos.

The debugging of the sensor array is complicated, and it is difficult to form a variety of array forms with different requirements
