==Use the Lidar with ROS==
A dedicated ROS node exists. To use it, a tutorial is available on ROS website. If you are using ROS on a recent environment (Ubuntu version >= 12.10 & ROS version >= Groovy) some changes have to be made.
- For the installation, point 1.1 of the tutorial. You get the hokuyo_node package by the command:
sudo apt-get install ros-groovy-laser-drivers - For viewing the data, point 1.7 of the tutorial. You monitor the data into the rviz tool with these commands:
rosrun rviz rviz -lthen, add a new LaserScan Interface and fill the following informations :
Fixed frame: /laser
Target frame: /laser
Topic: /scan
Now you can see
