TBD: Why is there a warning? (1/18/21) TBD: Today (2/1/21) I have a lot more errors
TELEOP: Teleop using the RC-100B

Optionm 2: Use Keyboard Teleop
This is without the RC-100B for example.
TERMINAL n Run Keyboard Teleop on the Remote PC on some free terminal.
Make sure this terminal is in keyboard focus and teleop using the following key commands.
$ ros2 run turtlebot3_teleop teleop_keyboard
