Package to run 3D SLAM with two 2d Lidars, pixhawk imu and the Cartographer package
3)roslaunch
roslaunch cartographer_ros demo_backpack_2d.launch bag_filename:=${HOME}/Downloads/cartographer_paper_deutsches_museum.bag
roslaunch cartographer_ros demo_backpack_2d.launch bag_filename:=/home/whu/data/cartographer_paper_deutsches_museum.bag
roslaunch cartographer_ros offline_backpack_2d.launch bag_filenames:=/home/whu/data/cartographerdata/cartographer_paper_deutsches_museum.bag
------------------------------------------- 20171022 Cartographer现已经支持Toyota HSR、TurtleBots、PR2、RevoLDS这几个机器人平台。
启动ROS
roscore
- revo_lds 例子 roslaunch cartographer_ros demo_revo_lds.launch bag_filename:=/home/whu/data/cartographer_paper_revo_lds.bag
2）hokuyo 新终端，启动hokuyo UTM-30LX ls -l /dev/ttyACM0 若显示为crw-rw----，则为其加权限使其显示为crw-rw-rw-
sudo chmod a+rw /dev/ttyACM0
roslaunch cartographer_ros demo_hokuyo.launch 3)2 hokuyo+imu
例子 roslaunch cartographer_ros demo_backpack_2d.launch bag_filename:=/home/whu/data/cartographer_paper_deutsches_museum.bag
4）myself 1 hokuyo+imu
sudo chmod a+rw /dev/ttyACM0 /dev/ttyUSBO roslaunch cartographer_ros hokuyo_IMU.launch
4）myself hokuyo
sudo chmod a+rw /dev/ttyACM0 roslaunch lidar_slam demo_hokuyo.launch
