飞行的社会昆虫可以提供模型系统的计算受限的空中机器人群在飞行中的相互作用。飞行昆虫中的社会相互作用可以通过最近的测量进展进行化学调制和量化，能够同时精确测量昆虫的翅膀和身体运动。本文介绍了第一次在飞行中定量测量暴露于乙醇的蜜蜂身体和翅膀的运动学档案文献。采用4台高速摄像机（9000帧/秒）记录蜜蜂（Apis mellifera）的翅膀和身体运动，通过数据关联、船体重构和分割，自动分析提取蜜蜂翅膀和身体运动的9000帧/秒测量值。使用统计分析工具研究了由暴露于从0%至5%的递增乙醇浓度引起的运动学变化。分析考虑了试验方式的平均值和最大值以及总的翼击参数，并使用Welch t检验和Cohen d检验来检验统计显著性的偏差。结果表明，在最大的标题和俯仰率的机构，并在高浓度（5%）的滚转率的影响减少。根据大量的翼击分析，翼击效应包括在浓度为2.5%或更高时，翼击频率降低和翼击幅度增加，翼击倾角逐渐增加至浓度为2.5%，并且随着浓度的增加，翼击更加平坦。这些乙醇暴露的影响提供了一个基础，以分离乙醇暴露和邻居的化学介导的相互作用的研究。
Flying social insects can provide model systems for in-flight interactions in computationally-constrained aerial robot swarms. The social interactions in flying insects may be chemically modulated and quantified via recent measurement advancements able to simultaneously make precise measurements of insect wing and body motions. This paper presents the first in-flight quantitative measurements of ethanol-exposed honey bee body and wing kinematics in archival literature. Four high-speed cameras (9000 frames/sec) were used to record the wing and body motions of flying insects (Apis mellifera) and automated analysis was used to extract 9000 frame/sec measurements of honey bees’ wing and body motions through data association, hull reconstruction, and segmentation. The kinematic changes induced by exposure to incremental ethanol concentrations from 0% to 5% were studied using statistical analysis tools. Analysis considered trial-wise mean and maximum values and gross wingstroke parameters, and tested deviations for statistical significance using Welch’s t-test and Cohen’s d test. The results indicate a decrease in maximal heading and pitch rates of the body, and that roll rate is affected at high concentrations (5%). The wingstroke effects include a stroke frequency decrease and stroke amplitude increase for 2.5% or greater concentrations, gradual stroke inclination angle increase up to 2.5% concentration, and a more planar wingstroke with increasing concentration according to bulk wingstroke analysis. These ethanol-exposure effects provide a basis to separate ethanol exposure and neighbor effects in chemically mediated interaction studies.
