中文摘要：

提出了一种基于动物捕食行为的机器人味源定位策略；该策略融合了气体传感器、风向传感器、超声传感器等传感器信息，考虑了搜寻味源过程中的避障及重复搜索问题，并给出了确认味源的条件．在动态的室内环境下，令机器人搜寻酒精泄漏源，结果表明，这种策略具有较高的搜寻效率和成功率．

英文摘要：

A gas/odor source localization strategy based on animal predatory behavior is presented, which fuses the information from gas sensors, wind direction sensors, ultrasound sensors, etc. Such problems in the gas/odor source searching process as obstacle avoidance and repetitive search are considered, and the conditions for gas/odor source confirmation are pres.ented. Experiments are made for the robot to search a leaking bottle with alcohol in a dynamic indoor environment, and the results validate the high efficiency and validity of the presented localization strategy.
