I’m working on a UAV project and I’m trying to use Aerostack2, a ROS 2 framework for developing and controlling autonomous aerial robots, together with ArduPilot.

I’ve been trying to make this work for a while by modifying the existing as2_platform_mavlink and project_mavlink components, but I’m having a hard time getting the integration working properly with ArduPilot.

Has anyone here worked with Aerostack2 + ArduPilot before? If so, what approach did you use, or are there any resources/examples you would recommend?

Any advice or pointers would be really appreciated. Thanks!

Hi all,

I'm running MAVROS (version 2026.6.6 build) on ROS2 Humble, connecting to ArduPilot SITL (ArduCopter) via a custom as2_platform_mavlink-based launch setup. My node runs in a non-default namespace (drone0/mavros).

I'm trying to block two specific plugins that are known to crash MAVROS in my setup — companion_process_status and debug_value — since they double-namespace their topics under a node literally named mavros, causing a create_subscription() invalid allocator crash.

Issue: plugin_allowlist does not filter plugins at all, even when correctly set. I confirmed via ros2 param get /drone0/mavros/mavros plugin_allowlist that the parameter is correctly present on the node with my intended values — but every plugin still loads regardless (created/initialized in logs), as if the allowlist is silently ignored.

Workaround: Switching to plugin_denylist with the same two plugin names does work — confirmed via logs showing Plugin companion_process_status ignored / Plugin debug_value ignored.

Questions:

1. Is plugin_allowlist known to be broken/unreliable in recent MAVROS ROS2 builds?
2. Is plugin_denylist fully reliable now or better alternative to go with?
3. Is there a recommended, verified way to guarantee a specific plugin is blocked, other than checking node logs after every launch?

Any insight or pointers to relevant issues/PRs would be appreciated. Happy to share full config/logs if useful.

Thanks!

Hi everyone,

I’m designing a resin 3D printed electronics enclosure, and I need to add threaded inserts for M3 screws.

The inserts will not be heat-set because the part is resin printed. They will be glued into the holes instead.

The insert dimensions are:

• Outer diameter: 5 mm
• Length: 5 mm

My question is: how much material should I leave around the insert hole to avoid cracking?

For example, if the insert hole is around 5.1 mm diameter, what should the outer boss diameter be? Is 2 mm wall thickness around the insert enough, or should I aim for 2.5–3 mm?

The enclosure may experience some vibration, so I want the insert area to be strong but not too bulky because the part also needs to be cost-effective for resin printing.

Any advice from people who have used glued threaded inserts in resin parts would be appreciated.

I'm considering applying to the PURE program organized by Sabancı University, and I'd love to hear from anyone who has attended or been accepted before.

How beneficial was the program for you, both academically and professionally? Looking back, do you think the 2 months invested in the program were worth it?

One of my main concerns is the restriction on taking part-time jobs or other internships while participating. For those who attended, did the experience justify giving up other opportunities during that period?

I'd really appreciate hearing about your experiences, the skills you gained, and whether it helped with future research, graduate school applications, or career opportunities.

Thanks in advance!
