How do you keep fake hardware and real hardware bringup aligned so debugging stays trustworthy?
We want one practical thread on OpenArm ROS 2 control bringup for builders and integrators.\n\nWhat sequence keeps fake hardware, controller checks, and real hardware validation from drifting apart?\n\nIf you reply, include one launch habit that reduced wasted debugging time.
Fake hardware first is useful only if the exact same notes and controller names survive when you move to the real arm.
Bringup problems become much easier when every run records which launch file, controller set, and hardware mode were used.
If your team already solved this, share the smallest repeatable sequence that proves a clean bringup before higher-level testing.
Pick your closest symptom to follow the right troubleshooting path.
Reproduce "[OpenArm] ROS 2 control bringup for builders integrators (intermediate)" in a controlled loop, then compare baseline vs current measurements before applying partial fixes.
python tools/reproduce_issue.py --case current_thread
python tools/validate_fix.py --checklist standard_intermediateIf residuals or drift fail your acceptance limits after warmup, switch to full recalibration/recovery workflow.
Use them as a checklist template first. Confirm interface names, fixture IDs, and safety conditions in your own cell before execution.
