what if I am using px4? about aclswarm HOT 6 CLOSED

Hi @vxgu86!

Any autopilot can be used as long as you can send velocity commands. The core code is autopilot agnostic. The code that interfaces with the autopilot is in saftey.cpp.

I would suggest writing your own node that subscribes to the /goal topic that comes from safety.cpp (using snapdragon_msgs). Then, use mavros (or whatever) to relay the goal msg to the pixhawk.

@plusk01 I have questions when running simulation.
I could post picture here so I send you a email at gmail, could you help me please?
thanks, it's about global status error with map error

from aclswarm.

@plusk01 I still have not solved this error，could you help please

From @vxgu86:

hi,really nice job. and thanks for sharing
I have got some questions, could you share some idea?

##1 you said the following in the github:
To run a simulation (referred to as a trial) use the following incantation. There must not be a roscore running before you run this step.
$ rosrun aclswarm_sim trials.sh -f swarm6_3d -i

but if I start a roscore first, the command above could not executed due to that: A roscore is already running. Shutdown roscore and try again.

##2 when I click start, the RViz and rqt pop out like in the picture, but I could not see any motors,
there is global status error, nothing show up in the right window. I do not know how to fix this?

##3 you make this great job with Qualcomm Snapdragon Flight, could I say that, the "Qualcomm Snapdragon Flight" is like a mini-computer+pixhawk?
the ros nodes are running on the mini-computer part and send commands like changespeed to the flying control part like pixhawk?
and the "Qualcomm Snapdragon Flight" is a mixer that combine them together?

I am not familiar with pixhawk, not to say the "Qualcomm Snapdragon Flight".

##4 I recall some algorithm called CBBA, also from MIT, do the consensus have something in common with it?

do you have any explaniation or documents that I can learn from for the job, really great job ,and I want to learn from it.

thanks!!!!!!!!!

Thanks for your kind words!

1. The instructions say: "There must not be a roscore running before you run this step."
2. I have added an rviz file that automatically configures the sim visualization in a3d00bb. Pull and run the same steps again.
3. Correct, Snapdragon flight is a mini-computer + pixhawk autopilot. ROS runs on snapdragon flight Linux CPU side, sends motor commands to DSP/low-level microcontroller side.
4. Yes, we utilize CBAA in our distributed task assignment algorithm. See our paper for more details.

Hope this helps!
