Turtlebot3_navigation

[rohanblueboybaijal]

This is an experiment with the navigation stack of turtlebot

tf transforms are required to fix the trees

rosrun tf static_transform_publisher 0 0 0 0 0 0 map world 50
rosrun tf static_transform_publisher 0 0 0 0 0 0 map base_footprint 50
rosrun tf static_transform_publisher 0 0 0 0 0 0 odom base_footprint 50

Add joint_state_publisher to ensure wheel transform error gets resolved. Wheels joint are of type = continuous but we don't need to see the wheels moving.
In any case, add the following line to the launch file which you are running
<node name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher" />

However, there is still an issue with the lidar scan data.
