Hello,
I just finished upgrading my Bluerov to Heavy, and with the navigator card.
I followed the guides, and everything seems to have gone well.
However, when I arm my BlueRov in manual mode, the motors start spinning. I don’t remember this happening before I upgraded to navigator.
Can someone confirm that this is normal before I put it in the water? If not, could you help me fix it?
Thank you in advance for reading and for your help.
Hi @cedricscha
Welcome to the forums!
What mode is your vehicle in when you arm it? If not in Manual, it is expected for the thrusters to spin, as they work to stabilize the vehicle and don’t get a response in air. If you’re in manual and they start going, you may need to calibrate your joystick or verify it has been configured correctly.
Are you using Cockpit or QGround Control? What version of BlueOS are you using? Have you set the motor directions for your two new thrusters correctly?
Hi,
Thank you for taking the time to respond.
I have been continuing my tests since yesterday to try to find out where the problem is coming from.
In any case, I make sure to be in manual mode.
In Groundcontrol, there is no problem. When I arm the motors, they are off and only respond when I move the joystick.
In Cockpit, when I do the same thing, the motors start running immediately.
Cockpit: 1.15.2
BlueOS: 1.4.2
Qground 4.2.8
The motors were configured out of the water using the air blow technique.
For the moment, I have not yet put the ROV back in the water, given the problem with activating the motors when arming.
The joystick seems to be configured correctly, given that the same configuration was done on Qground and it seems to be working.
Thank you again for your help.
Hi @cedricscha -
I would guess Cockpit has not had the joystick axis setup correctly- particularly the vertical thrusters (axis z - 1000 to 0.) Can you share a screenshot of your joystick configuration, table view, at the top where motion axis are mapped? The documentation here may help you resolve this with the correct values.
Hello @tony-white,
Thanks for your help. I ended up doing the following on my setup:
Deleted and reinstalled Cockpit: No effect
Formatted and reinstalled the basic version of BlueOS on my Raspberry: OK, after connecting with Cockpit, everything is fine and it works.
So, I don’t know where the problem was, but at least now it’s OK.
Thanks again for the support.
