global_planner的全局的规划路径、里程计信息以及local_costmap的信息,输出是速度控制指令,作为控制器的输入。base_local_planner 局部规划一般是用base_local_planner包实现的,该包使用Trajectory Rollout和**Dynamic Window approaches(DWA)**算法,根据地图数据,通过算法搜索到达 ...
包base_local_planner提供了进行DWA(Dynamic Window Approach)的局部路径规划的工具和基本功能模块。 所实现的功能就是给定需要跟踪的轨迹和代价地图的情况下,根据当前的机器人和环境状态,计算用于控制机器人运动的速度指令。DWA算法的基本思想是,在机器人的控制空间(线速度、角速度指令)中离散地采样,对于每个样本指令,...

针对你遇到的问题“could not find a package configuration file provided by 'base_local_planner'”,我为你整理了以下几个可能的解决方案: 确认base_local_planner包是否存在: 首先,确保你的ROS系统中已经安装了base_local_planner包。这个包通常是navigation元包的一部分。你可以通过以下命令来安装它(以melodic版...
base_local_planner::TrajectoryPlannerROS是对base_local_planner::TrajectoryPlanner的ROS封装。 它在初始化时确定的ROS命名空间内运行,该接口继承了nav_core包的nav_core::BaseLocalPlanner接口。 如下是base_local_planner::TrajectoryPlannerROS的一个应用案例:...
