gazebo仿真踩坑--rviz中设定机器人的目标位置,move_base后台日志报错

启动仿真环境及各种节点(amcl,move_base,map_server)后,在rviz中设定机器人的目标位置,后台日志报错

[ INFO] [1571974242.864525935, 40.511000000]: Got new plan
[ERROR] [1571974242.964186066, 40.612000000]: Extrapolation Error: Lookup would require extrapolation into the future.  Requested time 40.585000000 but the latest data is at time 40.521000000, when looking up transform from frame [odom] to frame [map]

解决:move_base的包的版本有问题(用的是melodic),用kinetic的版本,重新加到navigation的文件夹下,重新编译即可

问题2:

[WARN]Map update loop missed its desired rate of 10.0000Hz... the loop actually to took 0.1665 seconds

 

解决:修改move_base.launch文件中的频率,使其低于实际的回环的频率即可,这里改为5Hz就可以了

 <node pkg="move_base" type="move_base" respawn="false" name="move_base" output="screen">
    <param name="base_local_planner" value="dwa_local_planner/DWAPlannerROS" />
    <param name="controller_frequency" value="5.0"/>
    <param name="controller_patiente" value="15.0"/>

 

 问题4:

gazebo仿真可以用来建图,但是进行amcl定位的时候,不需要开gazebo仿真环境(重点是很耗内存,电脑风扇一度呼呼直响~~),还必须得开高性能模式,不然根本起不来

 

-----------更新

问题3:

[ WARN] [1571977808.693309245, 5.969000000]: local_costmap: Parameter "plugins" not provided, loading pre-Hydro parameters

 时间比较久,复现不了问题,建议移步下面的链接解决
