Moving this comment to its own topic.
I got a motorized armļ¼BluePrintLabļ¼, which has three degrees of freedom. How can I integrate it into Pixhawk?
If anyone has any way to help me, I would be very grateful
thank you
Hi @17665200818,
This post indicates that BluePrint manipulators should be compatible with the BlueROV2 companion computer, and possibly controllable from QGroundControl as well.
I had a look on their website and they donāt seem to post specifics of the API or signals used to control their manipulators, but they do mention they provide āResponsive Integration Supportā, so Iād suggest you contact them directly at info@blueprintlab.com and ask about interfacing with BlueROV electronics. Theyāll no doubt be happy to help you get your manipulator up and running 
It would be interesting and useful if you can post a follow-up here afterwards for others looking to do something similar later on

OK, Iāll have a try in the way you provide, and if thereās any progress, Iāll share it to here again,
Thank you
