Implementing Ardupilot's EKF (Inertial_Nav) externally

I have worked with Ardupilot for a long time and I am very impressed with the EKF used there. I did some research and found out it was Paul Riseborough's Inertial Nav EKF. I would like to implement…Continue

"Hi, What are the values you published to "setpoint_velocity" topic to control pitch and roll. Could you please share the code snipet if possible. Thanks"

"Hi Jefferson,      I am trying to control the drone with companion computer using mavros , I want to know how to set the launch file so I can use APM stack, Is it all the same with px4 stack and using qgroundcontrol?"

"Hi  Vinh, In case you are still trying to use OPTICAL control.. Are you trying to use OPTICAL CONTROL with camera on the DRONE or external camera? ON DRONE control can be done using PX4FLOW, a 3DR camera.. Unfortunately this is all I have at…"

"Hi David, were you able to get send velocity commands to make your drone move autonomously with GPS? I am using only optical flow, but I am not sure how to implement it."

"where you able to get it working on c++. Ive done the example from dev.px4.io but I need more information on how exactly to request the FCU for velocity, accel, 3d pos and orientation."

"I cant claim to be much help, but a link to the cloned repository would be a start, if there is one. Anything that helps to simplify and document the code is a good thing in my opinion. "

Implementing Ardupilot's EKF (Inertial_Nav) externally

I have worked with Ardupilot for a long time and I am very impressed with the EKF used there. I did some research and found out it was Paul Riseborough's Inertial Nav EKF. I would like to implement this ekf on another personal project separate from APM, and I seem to be getting close, but the whole thing seems pretty complicated. I have cloned the Inertial_Nav github repository and modified one of the test harnesses until I think it seems to be doing what I want, but it seems a lot of the work…See More

"Yes!  Sorry I never posted when I found more information. I guess when no one else seemed interested I just kinda forgot about it.  If it is in guided mode, setpoint velocity commands do work. I honestly don't remember all of the…"

Offboard Control - MAVROS

I am working on doing external control of an autopilot using an onboard linux computer running MAVROS. I found the topic on mavros entitled "setpoint_velocity," But when I send that to the autopilot in guided mode with ESCs unplugged, nothing happens. It should set the setpoints for velocity, but in looking at the logs, the dvelx and dvely did not change to comply. I know this is possible using the Px4 stack, but I would prefer to avoid the complexity of switching to that and stick with the…See More
