针对无法获得可靠羽流流向信息不利于实现羽流追踪的问题,提出了一种基于决策树的羽流追踪移动机器人自主决策方法.该方法通过移动机器人两侧的浓度传感器采集到的浓度信息,利用追踪的行为规则建立决策树模型,获得行为决策信息,使机器人高效地追踪到羽流并精确地定位.由于浓度变化关系蕴含了羽流的流向及流速信息,从而取代了传统方法中流向及流速传感器.在扩散环境下,通过移动机器人羽流追踪实验,实现了良好的源定位效果.%Aiming at the problem that the reliable plume flowing direction information can not acquire, which is not con-ducive to achieve plume tracking, an autonomous decision-making method is proposed that is based on decision tree to solve the plume tracking problem of the mobile robot. In order to obtain behavioral decision information by this method, a decision tree model is established based on the concentration information collected by the concentration sensors on both sides of the robot and the tracked behavior rule, so that the robot can efficiently track the plume and accurately position it. The flow direction and velocity information of plumes are contained in the concentration relation, which replaces the flow direction and velocity sensor in the traditional method. In a diffusion environment, a good source localization effect is achieved by the mobile robot’s plume tracking experiments.
