ROS support for BlueROV2

Oh, now i understand! Grateful It will help me for my propose. My misunderstanding was when i “override” to a RC channel i was thinking that this action is a Digital Pin Write function (Arduino). But, if i understand, ArduSub works in some high level abstraction (in a concept of radio modelism), channels controls the “movement” not a digital pin, right?

Yes, exactly, take a look in ArduSub documentation about RC params list.

But, with curiosity, I have already try with mavros without success too:

roslaunch bluerov_ros_playground user_mav.launch

rostopic pub /mavros/rc/override mavros_msgs/OverrideRCIn “channels: [1600, 1500, 1500, 1500, 1500, 1500, 1500, 1500]” -r 10

Why not work?

Like I said before:
/BlueRov2/rc_channel1: Will not work because the frame doesn’t have pitch control.

Probably It’ll do something if you ARM the vehicle and use something like channels: [1500, 1600, 1500, 1500, 1500, 1500, 1500, 1500]
