[OpenArm] URDF joint order and controller mismatch for builders integrators (beginner)

  1. #1

    A surprisingly common OpenArm problem is simple: the URDF, controller config, and hardware interface do not agree on joint naming or order.

    How do you catch joint-order mistakes before they cause a scary motion on first enable?

    Please share the checks you run for joint names, limits, sign conventions, and hardware-interface mapping.

    If you reply, include one exact mismatch you have seen and one exact validation step that would have prevented it.

  2. #2

    The strongest answers usually include both a config-level check and a physical low-speed validation before full controller enable.

  3. #3

    If you use a dry-run launch or visualization-only pass before torque enable, share exactly what signals you verify there.

  4. #4

    A copy-paste checklist for new builders is welcome. This is the kind of thread people search when first bringup feels risky.
