Hi Gazebo Community!

This week’s meeting was held on 2026-03-09T18:00:00Z and the following is a summary:

• PMC Business:

  • We officially passed the proposal for the
    new Gazebo Release Cadence.
  • We also decided to change our meeting time from 19:00 UTC to 18:00 UTC,
    starting with the 2026-03-09T00:00:00Z meeting.

• New agenda items:

  • GSoC 2026 (Recurring): We’ve been accepted! Proposals are due by 2026-03-13T00:00:00Z. Mentor projects are due by 2026-03-16T00:00:00Z, student applications are due
    by 2026-03-31T00:00:00Z, and rankings by 2026-04-21T00:00:00Z. Please add
    proposals to the project wiki and help triage “Good First Issues” for students.
  • Gazebo-classic transition post-mortem: We reviewed the survey and discussed the reflection question “Big changes”. Topics included the maintenance burden of physics and rendering abstractions, and whether we should keep using shared libraries for systems (plugins) given performance costs. We plan to audit
    which plugins should be built-in versus loaded dynamically.
  • gz-math dependencies: We agreed to use Eigen internally in gz-math and make it a private build dependency to encourage its use for optimized
    data structures. See PR #721.
  • Magnetometer sensor issues: Discussed how to handle magnetometer default units (Gauss vs. Tesla) and coordinate frames (NED vs. ENU). Decided to continue discussion on the relevant pull requests.
    • Add unit and frame enums to Magnetometer protobuf message by bperseghetti · Pull Request #568 · gazebosim/gz-msgs · GitHub
    • Add unit and frame metadata to MagnetometerSensor output by bperseghetti · Pull Request #595 · gazebosim/gz-sensors · GitHub
    • Enable advanced magnetic field navigation simulations with WMMHR 2025 by bperseghetti · Pull Request #3373 · gazebosim/gz-sim · GitHub

• Updates:

  • Buildfarm: We had some issues with disconnected Mac machines, but most
    are back up. mac-five.sonoma is still failing.
  • Working on fixing protobuf warnings, Ogre gl3plus test failures, and msbuild warnings for dartsim.
  • Docs: PR open to add maintainer guidelines and mergify backport utility (#675).
  • Physics: Working on category bitmask support for Bullet-featherstone and Dartsim, and Mujoco integration (GetContactsFromLastStep).
  • Releases: Released new gz-physics packages with Dart 6.16 (announcement).
  • Implementation of gz-rotary packages and utilities is ongoing.

As always, the meeting notes are available at Gazebo PMC meeting weekly agenda - Google Docs.

The next Gazebo PMC meeting will be on 2026-03-16T18:00:00Z (See Open Source Robotics Foundation official events)
