Embodiment 2

[0071] Take flies as the insects to be tested, and use polishing paper with a particle size of 1 μm, 2 μm, 3 μm, 4 μm, and 5 μm to press the Figure 5 The arrangement shown in A is arranged as a sample plate, and the creeping force is tested when the particle size is 1 μm, 2 μm, 3 μm, 4 μm, and 5 μm when moving horizontally on a straight strip-shaped crawlway. The specific steps are:

[0072] Step 1, turn on the computer 84, turn on the side-view photography light source 73, and simultaneously turn on the r stepping motor 61 to drive the experiment box 3 to the horizontal plane, then turn on the x stepping motor 41, the y stepping motor 45, and the z stepping motor 51 to start Switch, drive the test box 2 to reset (the head end of the cantilever beam 11 is located 10 cm above the center of the test box 2), turn off the x stepping motor 41, y stepping motor 45, z stepping motor 51 and r stepping motor 61 start switch;

[0073] Step 2, open the test door 32 and the experiment do...

Embodiment 3

[0079] Take the spider as the insect to be tested, and use the polished paper with a particle size of 5 μm as the sample plate to test the maximum climbing force of the polished paper in the vertical position. The specific steps are as follows:

[0080] Step 1, turn on the computer 84, turn on the side-view photography light source 73, and simultaneously turn on the r stepping motor 61 to drive the experiment box 3 to the horizontal plane, then turn on the x stepping motor 41, the y stepping motor 45, and the z stepping motor 51 to start Switch, drive the test box 2 to reset (the head end of the cantilever beam 11 is located 10 cm above the center of the test box 2), turn off the x stepping motor 41, y stepping motor 45, z stepping motor 51 and r stepping motor 61 start switch;

[0081] Step 2, open the test door 32 and the experiment door 22, take a sample plate 23 to be tested, cut it into a size of 10cm×10cm, and paste it on the inner bottom surface of the experiment box 2 ...

Abstract

The invention provides a device and a method for measuring climbing force of an insect in multiple poses and in different climbing ways. The device comprises a force measuring unit, an experiment box, a test box, an x and y axis moving mechanism, a z-axis moving mechanism, a rotating mechanism and a charge coupled device (CCD) imaging system. The method comprises the following steps of: rotating the test box to a required angle, tying the insect to a head end of a cantilever beam by using a wire, putting the insect on a sample board with different-roughness climbing ways, and matching overlooking shooting with side-looking shooting to measure gaits of the insect and a position of the insect in the space; and measuring vertically downward component force and horizontal component force of the insect through two bridge circuits consisting of y-axis strain gages and z-axis strain gages, which are uniformly arranged at the root of the cantilever beam, thus obtaining the climbing force when the insect climbs or a sample table descends. The device realizes non-interference measurement of the climbing force of the insect in a three-dimensional space, can be used for analyzing the tendency of the insect in the three-dimensional space in the testing process, and has the advantages of simple operation, low testing interference, accurate measurement and the like.

Description

technical field [0001] The invention relates to a crawling force measuring device and method suitable for insects crawling in multiple postures and on different crawlways, and belongs to the technical field of living organisms and surface crawling force measurement. 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). Pods living on the ground realize driving, stabilizing, maneuvering and other motion behaviors through the interaction between the soles of the feet and the ground. In particular, people often see flies, ants, crickets and other insects crawling quickly on smooth surfaces, and even hang upside down from the ceiling. This has attracted the interest of numerous biologists and has led to extensive...
