Turtlebot3多机建图教程-多机测试

说明：

  • 介绍如何执行多机测试

相关设备：

步骤：

  • [Remote PC] 启动rosore
$ roscore
  • [TurtleBot] 启动第一台小车
$ ROS_NAMESPACE=tb3_0 roslaunch turtlebot3_bringup turtlebot3_robot.launch multi_robot_name:="tb3_0" set_lidar_frame_id:="tb3_0/base_scan"
  • [TurtleBot] 启动第二台小车
$ ROS_NAMESPACE=tb3_1 roslaunch turtlebot3_bringup turtlebot3_robot.launch multi_robot_name:="tb3_1" set_lidar_frame_id:="tb3_1/base_scan"
  • 效果如下：
PARAMETERS
 * /rosdistro: kinetic
 * /rosversion: 1.12.14
 * /tb3_0/turtlebot3_core/baud: 115200
 * /tb3_0/turtlebot3_core/port: /dev/ttyACM0
 * /tb3_0/turtlebot3_core/tf_prefix: tb3_0
 * /tb3_0/turtlebot3_lds/frame_id: tb3_0/base_scan
 * /tb3_0/turtlebot3_lds/port: /dev/ttyUSB0
