A convenience file is provided to launch Gazebo, RVIZ and Navigation2 using a single command: Where can used to replace any of the default options, for example: Before running the command make sure you are sourcing the ROS2 workspace, setting the path to the Gazebo model and defining the TB3 robot model to use. The nav2_bringup package is an example bringup system for navigation2 applications. By default, Navigation 2 waits for you to give it an approximate starting position. However, providing a map is not required to use Nav2. Overview 2. Dynamically composed bringup is used by default, but can be disabled by using the launch argument use_composition:=False. Were currently having build issues on 16.04. This information is applied to the AMCL algorithm. As a result the centre of the laser scan has changed, too. * Sometimes setting use_sim_time a second time is required for all the nodes to get updated The path of my_map.png in my_map.yaml is relative. For example, a workspace has the following layout: Check if the location of name of your map.pgm in name of your map.yaml is right. To start an empty Gazebo world similar to the rosrun command in the previous tutorial, simply run roslaunch gazebo_ros empty_world.launch roslaunch Arguments You can append the following arguments to the launch files to change the behavior of Gazebo: Click on the approximate point in the map where the TurtleBot3 is located and drag the cursor to indicate the direction where TurtleBot3 faces. * Send the robot a goal using 2D Nav Goal button. The nav2_bringup package is an example bringup system for Nav2 applications. Step 3: Play aroundWhen the robot is on the way to the goal, you can put an obstacle in Gazebo: Launch the simulator. The TurtleBot3 documentation uses the unix command 'export' to set environment variables, instead use the following: set TURTLEBOT3_MODEL= waffle NOTE: The value of %TURTLEBOT3_MODEL% is case-sensitive. Learn 13.
