Any RTK GPS should work. The corrections are from L1/L2/L5 base stations. We've tested with the Ublox F9P and Septentrio Mosaic-X5 as rovers.

Just 80/20 aluminum extrusion.

Me too and I don´t understand why. Can anyone help?

It about 60-80Hz

@@arkelectron Thanks! That’s great,it is worth trying. Any suggestions for the Jetson nano selection? My setup: kzfaq.info/get/bejne/bd2jbK1l2LSygKs.htmlsi=xhKxP-SZC_D-IY-V

Same issues, what we can do?

hit L4 and L5 at the same time. Or just L5

With ubuntu 22.04, after cloning PX4-Autopilot repository as described in the tutorial, gazebo garden is installed by default and all models including x500 (gz_x500) is automatically installed. Make sure to run the bash script for the gazebo to be installed as the tutorial says. Also it does run the command make px4_sitl gz_x500, but it is done through the processes.py file in the ros2 offboard package src

This is with stock VLSAM and nvBlox configurations. It is a rosbag recording.

Cool, did you have any issues with the realsense? Specifically the realsense splitter node if that sounds familiar?

@@alexdesaram164 You can find updated work on this here. github.com/ARK-Electronics/isaac_ros-dev

Build and flash the latest main of PX4 for the ARK Flow firmware. Then check out this PR for your flight controller. There were some regressions from when this video was filmed that have been recently resolved. github.com/PX4/PX4-Autopilot/pull/22145

Overall I'm very happy with the enclosure. The side middle vertical supports were needed to mount the gas struts. I like that it's strong enough to use the back top as a shelf.

You need QGround Control open

@@immanuelampomahmensah7909 Can you explain more on how to do that? Thanks!

It appears that the fixed wing position controller supports trajectory setpoints in offboard mode. github.com/PX4/PX4-Autopilot/blob/main/src/modules/fw_pos_control/FixedwingPositionControl.cpp#L2182-L2185

It should

You might be able to. I haven't tested it in wsl2.

I've used Windows 10 and wsl2- the 'make' process on px4_msgs and px4_comm packages wasn't done overnight. For context, I used an 8GB RAM, 2.7GHz 4- cores computer. So, I just ended up switching the OS to Ubuntu 22.04 and it took only 30 minutes as it had in the past on a raspberry pi 4 8GB RAM

This is only for ROS2.

@@arkelectron Can i install ROS2 in parallel to ROS1 setup as the first of having the PX4 from gitbub is the same for both ROS 1 and ROS 2 . please advice....thank you

I have to second this!! I have spent weeks trying to get my Cube Orange to connect to my host computer from the jetson nano with the new uXRCE-DDS the PX docs about the agent are very vague!!

@@wmlong777 Follow the instructions in the docs for building from source. Then on 1.14 or main PX4 set the param UXRCE_DDS_CFG to the port you want to use. On the companion computer run "sudo MicroXRCEAgent serial --dev /dev/AMA0 -b 921600" pointing to the serial port you are using. docs.px4.io/main/en/middleware/uxrce_dds.html#micro-xrce-dds-agent-installation docs.px4.io/main/en/middleware/uxrce_dds.html#starting-the-client

I have been stuck on this for couple of minutes until I realised the connection just needs some time. I followed docs on px4 site (linked above by @arkelectron). Used serial connection and nothing happened (my DDS agent didn't connect and topics were not created). I was searching around and turned out that after I left this setup for some time it finally managed to connect. It may be buggy or my setup was just slow. I used SiK Holybro telemetry radio (can't remember which version) as serial device, and other end of this radio was connected by USB to my laptop where I redirected this USB device to WSL2 instance using usb-ipd. On WSL2 then I started DDS agent and it worked like a charm, I could use ROS2 without cable connected to the flight controller (Pixhawk 6X).

If you are using an ARK Flow, it is coming over CAN. docs.px4.io/main/en/dronecan/ark_flow.html

What is the maximum range in alititude poshold ?

Without GPS, about 10-15m over grass. Around 20-25m over hard surfaces.

Yes you can use it to fly in gps denied environments.

@@arkelectron thank u :))

@@arkelectron hello friend, may I ask one more question that which mode are u in when u takeoff ? I mean I usually takeoff in stabilized mode, if I use the optical flow, it is possible I can take off in position mode ? it seems need has a good position lock first, thank u

@@shuaili5656 With optical flow, you can take off in position mode.

@@arkelectron great thanks !

It's an Ekornes Stressless look-a-like.

It is in the PX4 main branch right now.

Take a look at this video, most of the PX4 side setup should be the same. kzfaq.info/get/bejne/eNibnpOL0tSrl6c.html

I sized the enclosure height to account for the highest possible mounting of the spindle. My enclosure ended up being ~70cm tall from the base of the machine.

Thanks bro! 🦾

Thanks for the tip. I've used it once so far before I had a better fixture solution.

@@arkelectron Nice! The HDM really needs good workholding. I got the SMW fixture plates with mod vises for my HDM and I will not look back. :)
