物理机器人导航到目标点之后不会停下来
ros2 galactic Ubuntu20.04 阿克曼底盘
采用navigation2导航堆栈中的Hybrid-A*算法插件和teb插件进行单点导航
车子运行到rviz上发布的目标点之后,不会停下来。全局规划器会继续规划一条圆圈形状的路径继续往前走。
如上图,绿色点为rviz上发布的目标点。
如上图,车辆到了目标点之后,会继续往前走。
请问为什么车辆到了目标点不会停下来?有什么解决办法没?谢谢各位大佬!!卡在这好久了,忘大佬们伸伸手帮一下 -

rosdepc无法安装依赖
ros2版本galactic
在导航实物部署中,想使用teb_local_planner算法对dwb算法进行替换,但在teb算法的源码安装中出现编译时缺少libg2o依赖库的问题。于是想使用rosdepc安装libg2o依赖库。
运行命令:rosdepc install -i --from-path src --rosdistro galactic -y
出现错误:欢迎使用国内版rosdep之rosdepc,我是作者小鱼!
欢迎关注公众号《鱼香ROS》加入交流群
小鱼rosdepc正式为您服务
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
teb_local_planner: Cannot locate rosdep definition for [libg2o]rosdepc已进行过init和update
求助怎么解决 -
导航实物部署
在实物机器人上面进行导航部署,已完成建图操作。实物机器人能提供里程计信息。传感器为镭神m10_p激光雷达。但在进行导航实践时出现错误:

nav2进行导航时出现错误,求助!!
根据《动手学ros2》进行fishbot的nav2导航仿真,在执行程序:
ros2 launch fishbot_navigation2 navigation2.launch.py
时终端出现以下错误:

对照github上鱼哥发的源码,发现代码部分不存在问题
当前使用的是ros2-eloquent版本,ubuntu是18.04,源码安装nav2和apt安装nav2都尝试过,均出现以上错误。
卡了好几天,希望大佬帮助一下,感谢!!

RE: 求助,源码安装cartographer出错
@小鱼 ros2版本是eloquent,ubuntu版本是18.04。ros2安装了,rosdepc也装了。根据《动手学ros2》中进行cartographer的源码安装,报错如下:
1.使用rosdepc安装所需依赖:
rosdepc install -r --from-paths src --ignore-src --rosdistro $ROS_DISTRO -y
时出现以下错误:欢迎使用国内版rosdep之rosdepc,我是作者小鱼!

gazebo.launch.py文件中那个urdf_name中的gazebo_base.urdf改成fishbot_base.urdf就可以了,我是这样的 -
求助啊大佬们
在用launch方法生成gazebo启动项和导入urdf文件时出现以下错误:
spawn_entity.py-2] [INFO] [spawn_entity]: Spawn Entity started

launch文件如下:
import os
from launch import LaunchDescription
from launch.actions import ExecuteProcess
from launch_ros.actions import Node
from launch_ros.substitutions import FindPackageSharedef generate_launch_description():
robot_name_in_model = 'fishbot'
package_name = 'fishbot_description'
urdf_name = "fishbot_gazebo.urdf"ld = LaunchDescription() pkg_share = FindPackageShare(package=package_name).find(package_name) urdf_model_path = os.path.join(pkg_share, f'urdf/{urdf_name}') # Start Gazebo server start_gazebo_cmd = ExecuteProcess( cmd=['gazebo', '--verbose','-s', 'libgazebo_ros_init.so', '-s', 'libgazebo_ros_factory.so'], output='screen') # Launch the robot spawn_entity_cmd = Node( package='gazebo_ros', node_executable='spawn_entity.py', arguments=['-entity',robot_name_in_model,'-file',urdf_model_path], output='screen') ld.add_action(start_gazebo_cmd) ld.add_action(spawn_entity_cmd) return ld
结果是:gazebo启动成功,但是未导入文件
