ros2 launch nav2_bringup rviz_launch.py

Run Teleop on PC

ros2 run teleop_twist_keyboard teleop_twist_keyboard

Drive the robot around to create map

To load in map and navigate:

ros2 launch nav2_bringup bringup_launch.py use_sim_time:=False autostart:=True map:=/home/user/ws/src/navigation2/nav2_bringup/bringup/maps/map.yaml

Set the robot's pose. Select a target goal on the map and the robot will autonomously navigate there.
