Using Vicon Data from ROS and feed it to the Mambo Parrot Drone Flight Control System in Simulink

1 visualizzazione (ultimi 30 giorni)
Hi there,
I am trying to interface the Mambo Parrot Drone with a Vicon Motion Capture System. I am accessing the Vicon data through ROS on my Ubuntu laptop. I also have Matlab 2018b & Simulink installed on the same laptop. I want to feed the pose estimate of the Mambo Drone that is captured by Vicon to the Mambo Flight Control System in Simulink. Could you please advise how this can be done?
Thank you.

Hello Ben,
If you have the Vicon pose estimate coming in over your ROS network, you can access it directly in Simulink through the use of the Subscribe block.
If the information coming in over ROS from Vicon needs processing to translate it into a usable pose estimate, that can still be accomplished. If the processing is done out of MATLAB, you can simply have the code re-publish on a different ROS topic, and have Simulink listening for that. If the processing is done in MATLAB, you can do that too, but there are better alternatives. The most efficient would probably be to add the processing to the Simulink model as native blocks. An alternative would be to put your MATLAB code that does the translation in as a MATLAB Function Block.

Hello Ben,
Yes, you will need to make the custom messages available to MATLAB in order to use them within Simulink. Please see the documentation on how to do so.
