本文研究了化学羽流示踪（CPT）性能与气味传感性能之间的关系。化学羽流的跟踪起着重要的作用，因为它有助于识别气味源。传统的研究集中在CPT算法的开发上，而性能气味传感器对CPT性能的影响尚未研究。因此，在这封信中，我们首先比较了具有高CPT性能的昆虫（蚕蛾，家蚕）的嗅觉特性和人工气味传感器的特性。特别是，我们重点关注和比较了两种类型的传感器，这在气味信息的获取中起着重要的作用的恢复时间。结果，确定昆虫嗅觉传感器的恢复时间比人工气味传感器的恢复时间快十倍。我们还通过实验评估了这种差异对CPT性能的影响。利用蚕蛾和机器人进行的CPT实验表明，CPT性能与传感器恢复时间之间存在相关性。因此，它被证明是必要的，不仅要改善算法，而且传感器的恢复时间，以提高CPT性能。
In this letter, we investigated the relationship between the performance of chemical plume tracing (CPT) and odor sensing property. Tracking of chemical plumes plays an important role because it facilitates the identification of an odor source. Conventional research has focused on the development of CPT algorithms, whereas the influence of the performance odor sensors on CPT performance has not been investigated. Therefore, in this letter, we first compared the olfactory characteristics of an insect (silkworm moth, Bombyx mori), which has high CPT performance and the characteristics of an artificial odor sensor. In particular, we focused on and compared the recovery times of the two types of sensors, which plays an important role in the acquisition of odor information. As a result, it was determined that the recovery time for the insect olfactory sensor was ten times faster than that of the artificial odor sensor. We also experimentally evaluated the effect of this difference in the recovery time on CPT performance. CPT experiments using silkworm moths and a robot revealed that there was a correlation between the CPT performance and sensor recovery time. As such, it was demonstrated that it is necessary to improve not only the algorithm but also the sensor recovery time to improve the CPT performance.
