Based on the naming of the device port it looks like you are using the Rover Zero. If that is the case then you will want to use rr_rover_zero_driver rather than rr_openrover_driver. You will want to launch using roslaunch rr_rover_zero_driver example.launch. This just launches the driver.

Here is a tutorial on our website to setup the rover-zero: Tutorial
