Research On Robot Olfactory Perception And Localization Under Bionic Mechanism

Inspired by the animal olfactory function, more and more scholars begin toresearch the robot olfaction, the toxic gas leakage source localization has become one ofthe research focus. Gas leakage source location technology is also known as the robotactive olfaction technology, which can be used to plant inspection, fire rescue and so on,with emphasis on social security nowadays, robot active olfaction technology hasattracted more and more attention. In this paper, the odor source localization has mainlydone the following research:Analysis the commonly used gas diffusion model, and use Matlab to simulateGauss gas diffusion simulation model, and analysis the influence of the wind speed ongas diffusion. Using Fluent to do the simulation of indoor smoke plume diffusion.Through the analysis of domestic and foreign odor source tracking algorithm,designed the robot gas leakage source localization algorithm that combined with Zshape search strategy and evolutionary gradient algorithm, we simulated the leakage ofgas algorithm in Matlab software and proved the feasibility of the algorithm.To build a mobile robot system and equip with wireless positioning suite on themobile smell robot at the same time, so that it can transmit the position information tothe PC terminal.Design the experiment of indoor mobile robot localization, then the mobile robotcan conduct odor source localization in a simple indoor environments and transmit theodor source coordinates to the PC.The main job of this paper is to design the odor source location strategy based on Zsearch algorithm and evolutionary gradient search algorithm. Inspired by the animalolfactory function. Meanwhile, the gas leakage source positioning robot is installed inthe wireless position system, which can obtain the coordinates of the source of the gasleakage.
