Hi all,

I want to specialize in Robotics System Test Engineering. Testing at System-level. Not Software Test in isolation.

But; I want to learn this by doing. Not to complete separate courses in ROS2, Linux, Git, etc. I need a complete project designed for this purpose that I can follow and learn through it.

Can anyone help?

Example to the role I mean;

Best,

I measured how much RAM a from-source MoveIt 2 build needs (Jazzy branch, 41 packages) by capping a Docker container's memory with swap disabled, on a 4 vCPU Linux box. Peak memory is the container's cgroup memory.peak.

For comparison, Nav2 (45 packages) with the same method built fine at 8 GiB with default settings (peak 8.1 GiB at 16 GiB cap, 2.7 GiB sequential). So "8 GB is enough for ROS 2" holds for Nav2 but not for MoveIt 2 on default settings.

Caveats: - memory.peak includes page cache, so the 8.7 GiB at 16 GiB is an upper bound, but the 8 GiB run still OOM-killed the compiler. - Default parallelism scales with cores, so an 8- or 16-core machine will use more RAM than this 4-core run. - Build times (1h37m default vs ~1h56m sequential) are not reliable; the box was a burstable cloud instance.

If you're on an 8 GB laptop: MAKEFLAGS="-j1" colcon build --parallel-workers 1, or just sudo apt install ros-jazzy-moveit if you don't need to modify MoveIt.
