One shortlisted system moved pucks from a neatly prepared tray and another used our uneven workshop presentation, so I want to agree a common fixture-to-tray task before interpreting the more graceful video as the better purchase.
Our handling review needed the interrupted cases as well as the clean sequence. For your shortlist, compare the same identified pucks, tray preparation, loading and release, with staff assistance stated. Then list the recovery and handover questions the clips do not answer.
The suppliers have received a common task description with our tray and preparation work included; I have kept the existing videos as limited examples, not a ranked comparison, while they respond.
