We are having trouble getting the claw to work with q ground because the actuator function appears to be removed from blue os
Hi @john2 -
Welcome to the forums!
What do you mean by
?
This post may be helpful in understanding the transition ArduSub made with respect to actuators and servo outputs. Let us know if you keep having issues!
Also, try out Cockpit - we’re preparing to abandon QGround Control! A big documentation update is coming…
hi so the problem i am having is that in your tutorial to set up the newton sub sea gripper you use actuator which appears to have had the name changed and i just need to know what to set it to so the servo min max monetary commands in q ground actually works
Per the linked post:
e.g. if you set an output’s servo channel function to Actuator 1 (184) then you should be able to use the servo_1_* button functions in QGC to control it. In updated software you should be able to use the actuator_1_* button functions instead - they’re the same functions, they just use a new name.
I’m struggling with this as well. My config is as follows:
Flight controller: Pixhawk1
Ardupilot 4.5.7 (STABLE)
BlueOS 1.4.3
For accessories, I have lights, camera, Gripper, Ping360, and DVL. While the lights, camera, Ping360, and DVL all work, I can’t seem to get the Gripper to work. There is no option for Actuator1 in the Parameter Editor, although I think it sees it because it shows Gripper on Aux 1 on the Overview page. I have it plugged into port 11. It also shows Custom: 186 under Output 11?
In cockpit, I’ve tried to set Actuator 1 Max/Min Momentary joystick actions, but nothing happens. Any guidance is appreciated.
The output displays sometimes get cached weirdly in browsers - it may help to try connecting via a different valid access domain (e.g. http://blueos-avahi.local, or a direct IP address), or using a different Chrome profile.
Nice displays aside, per the quoted table 186 corresponds to Actuator 3, which matches the previously hardcoded servo function from older ArduSub versions for output channel 11. If you want to use the actuator 1 button functions you’ll need to change it to 184, otherwise you can just use the actuator 3 button functions - either approach should work 
Thank you Eliot. I used actuator 3 and it’s working again! So much appreciated.
