Move turtlebot3_mecanum_core package to your Arduino folder.
You can draw the map using 'mecanum_teleop_key' code in 'turtlebot3_teleop' package.
Before run 'roslaunch turtlebot3_navigation turtlebot3_navigation.launch map_file:=$HOME/map.yaml', you have to add 'export TURTLEBOT3_MODEL=mecanum' to the your bash file.
You can use the open source package 'follow_waypoints' to set the waypoints in the map.
