How to read acceleration from APM using mavlink (c++)?

Started this discussion. Last reply by Fernando Lima Saraiva Filho Apr 25. 19 Replies

Hello all,Recently I started working with APM and mavlink. I'm trying to get attitude and acceleration data from APM via USB. So far I was able to receive RPY data correctly but I can't seem to be…Continue

UAV control using Novint Falcon haptic device

In the last two months I was exploring an idea of using a haptic device to control a multirotor. Here is the video I made showing the system working in simulation:The setupFor the simulation I used Px4 SITL running with jMAVSim. For interfacing with Px4 I'm using mavos + two custom ROS nodes. If you are interested in trying it yourself then you can find all source code in the following repo: …See More
