00:00:00,400  -->  00:00:06,360
in order to make the turtle robot the first
step is to install the ROS  robot operating

00:00:06,360  -->  00:00:12,880
system into your ubuntu machine so if you
have ubuntu 20.04 then you will need to install

3

00:00:12,880  -->  00:00:22,400
ROS 2 foxy but if you have 22.04 ubuntu version
Then you will have to install ROS 2 humble
