Universal_Robots_ROS_Driver VS PX4-Autopilot

They have a section for developer about ROS UR ROS

This is the Ros driver for ur-e series robot. You can simply follow the readme to setup a simulation involving a rviz model and some.basic planning and associated visualisation.

That’s not windows. It uses ROS

Oh no, really? I'm following the directions of this GitHub page which includes features such as "Realtime-enabled communication structure to robustly cope with the 2ms cycle time of the e-Series. " and then says, "To make sure that robot control isn't affected by system latencies, it is highly recommended to use a real-time kernel with the system."

They are widely used in narrow circles :)

Two of (arguably the best) open source RC aircraft flight controllers (ArduPilot and PX4) are using extended Kalman filters in their state estimators (essentially sensor fusion that provides attitude/position estimate):

I'm not that familiar with cleanflight/betaflight/inav scene to know what the FPV racer flight controllers use.

Actually, even the General Aviation pilots who actually manually manage their own load-shedding during a mission would quite like automated power distribution and management systems... and if you felt like taking on that sort of work as a hobby project to cut your teeth, I bet the guys at the (open-source) PX4 project would bite your hand off...

As a flight pilot engineer you have to find a sweet spot and balance logging too much and too little. Writing logs to an SD card has huge costs that come with it, that's why you don't want to log too much. Logging too little and you can't debug issues later on properly.

PX4 also has lots of "topics" logged at around 1/10, e.g. hover thrust estimate every 100ms:

Okay, but nowadays most people talk about “Pixhawk” as an open-standard hardware platform and PX4 as the software. The source code is at https://github.com/PX4/PX4-Autopilot and they call themselves “PX4 Autopilot Software”.

As an example, PX4 is a popular open source drone autopilot software: https://github.com/PX4/PX4-Autopilot

I am working as a Remote Embedded Software developer for quite a while now and there is no obstacle in Remote work. If I am missing anything, parts are arriving in under the week. That said, I never had a better work-life balance in the last 10 years. Anyone who said Embedded is not possible to do remotely just check any open source flight controller project (in my case PX4).
