racebot入门教程-导航-自主导航(teb算法)

说明:

  • 介绍如何通过racebot进行自主导航

相关设备:

步骤:

  • [RaceBot] 启动底盘
$ roslaunch racebot minimal.launch
  • [RaceBot] 启动转换程序
$ roslaunch racebot keyboard-diff.launch 
  • [RaceBot] 启动amcl
$ roslaunch racebot amcl_demo.launch map:=/home/ubuntu/map/gmapping_map.yaml
  • [Remote PC] 启动RVIZ
$ roslaunch racebot nav.launch(新版)
$ roslaunch turtlebot_rviz_launchers view_navigation.launch --screen(旧版)
  • 初始化位姿
  • 设置导航目标点
  • 小车则自动导航到目标点

  • 如果小车没有如期运行,处于抖动状态,可以尝试更改参数配置:

roscd racebot/param/teb 
vim move_base_params.yaml 
  • 修改参数为如下:
base_local_planner: "teb_local_planner/TebLocalPlannerROS"
controller_frequency: 3.5  # a number describing how often the local planner is asked to compute new velocity commands. This also has a high impact on low cpu resources. A value of 10 hz might be a good start.
controller_patience: 2.5
  • 或微调上面的参数值
