Hi! I am starting a project where i will need to automatize a BlueROV2. For that i need to send basic controller commands via a script, for example up or down, and receive sensor information on the same script. Can anyone tell me where is the best place to start? I am a bit lost in the ardusub/mavl…

I modified the /home/pi/companion/.companion.rc with added one line sudo -H -u pi screen -dm -S zidingyi /home/pi/companion/scripts/zidingyi.sh And I write my code in zidingyi.py [clipboard] with master = mavutil.mavlink_connection(‘udp:192.168.2.2:9001’) master.wait_heartbeat() #buttons = 1 <…

Use 0.0.0.0 for your ip address. The 192.168.2.2 address is not assigned until the computer actually connects to the network.

I think the problem was sovled! Without ethernet connected, I can run the scripts you offered with the modification of ip. I am not very familiar with Rpi and I even think the QGC safety protection disarm the vehicle:sweat: Thank you very much for your help!!:grinning:

Hi,Jacob I am considering using 2 RPIs to work at the same time. I connect the the two RPIs by a switch. The ips of the RPIs are 192.168.2.2, 192.168.2.7 respectively. And 192.168.2.2 is conneccted to my laptop QGroundControl. I can login in the RPI by putty ssh whose ip is 192.168.2.7 and does not…

Hello jacob I have worked on making ROV autonomous recently and I succeed in running python scripts in RPI and control ROV with QGC connected. However, when I shut down my QGC and send a command move backward, def move_backward(speed,timesec): print("movement_action") master = mavutil.mavlink_c…

Hello, The ROV will go backward without stopping Check if the code will exit from this loop, what is the value of timesec that you are using ? Can you send us your full code via github or pastebin ? when QGC connected, the backward motion will last for timesec seconds. Yes, QGC is sending ma…

Hi, Sorry for my late response. I tested your code in my ROV without QGC connecting and I found my ROV works different from yours. Once I run the code in a manual mode, the machine would be active even though the python program had finished. And when I armed the machine in depth hold mode, only …

Please, let’s see the code, and maybe a video too to make it clear the behavior that you are observing.

from pymavlink import mavutil import time #Create the connection master = mavutil.mavlink_connection('udp:0.0.0.0:9000') master.wait_heartbeat() print(master.target_system) buttons = 1 << 6 master.mav.manual_control_send( master.target_system, 0, 0, 0, 0, buttons) print("arme…

[image] ggttkl: The machine should be stopped after the code finished while it isn’t. The machine move forward even though the code have finished. No, you need to tell the machine to stop with your code.
