A precision task. An inspectable robot run.

Small holes. Real collision geometry. Pick the populated board, align its mounting holes, engage the locating pins, release and inspect.

the task

Precision has to exist in the physics.

The original CAD provides populated components, connectors and open mounting holes. Convex collision pieces preserve those openings instead of filling them with a hull, so the pins can actually engage.

  1. 01
    Pick the populated board

    Lift it from the input nest without disturbing the components.

  2. 02
    Align and engage

    Bring the mounting holes over the round and relieved locating pins and lower the board onto them.

  3. 03
    Release and inspect

    Let go, check the seating from the cameras, then retrieve the board vertically.

  4. 04
    Place in OUTPUT

    Set the board down in the output nest and withdraw.

measured results

Check the outcome.

The published run was measured against independent command replay and the fixture geometry.

Results for one nominal simulated arrangement with rigid parts and estimated contact parameters. Electrical testing and hardware transfer are unvalidated.
