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…

Hi @gilpinheiro , You can use ROS (mavros package) or pymavlink . Take a look in Using MAVLinks commands to intepret RC command inputs for use in ArduSub and Simulating Manual Control using Mavros , both can be useful. What exactly do you want to accomplish ?

Thank you for your answer! So the mavros package and pymavlink have the same roll right? It will be something quite simple. We will only use the internal sensors (gyroscope, accelarometer and baromete) and we are planning to run the mission offline (no tether connected). So, the robot will need to…

pymavlink is a python implementation of the MAVLink protocol, actually it’s a submodule of the mavlink package. mavros is a ROS-MAVLink abstraction package, it’ll provide /mavros/* topics for ROS development. Mavros need the mavlink package (that comes with a specific version of pymavlink) to op…

Thanks a lot for your input @patrickelectric ! Unfortunately no, it will be a rather simple project, as me and the rest of the team have a severe lack o time :frowning: I hope to give you news soon!

I am trying to install pymavlink on ubuntu through their installation README, but i get the following error when testing: from pymavlink import mavlinkv10 as mavlink Traceback (most recent call last): File “”, line 1, in from pymavlink import mavlinkv10 as mavlink File “/home/gilp/anaconda3/en…

SITL is a simulator right? No, i am not running it! So, can i test without SITL or the BlueROV2 connected? I completed the README (although not sure if i have done it correctly…) and in the installation i chose the developer option, right? I will try the example you gave me later and give you som…

The best option if you want to start working with this kind of integration is with S.I.T.L (Software In The Loop) , you can run ArduSub with it. As far as I know, you’ll need something to communicate via mavlink with your code, like: BlueRov2, SITL, pixhawk and etc. SITL in the best option for devel…

I will test the simple code you gave me today with the BlueROV and I will give you feedback later! This is the main idea of what we want to do: [Bluerov] But there is still a lot of confusion on how to accomplish it… Our main two doubts reside in these main points: How to receive the sensor da…

Hi @gilpinheiro , How to receive the sensor data in our python program, running in the Odroid? This program will calculate our robot current location using this sensor data received. With pymavlink, you can use my example as a prove of concept. You can get more information about pymavlink api he…

Can you say exactly what are you doing and which step are you in the readme ?
If you want to test pymavlink, you can try this simple udp example, if you’re not running the SITL, please change the localhost to 192.168.2.1
