PUDA Machine Vision Validation

Goal

Provide one machine-neutral visual safety gate for PUDA-connected machines at BEARS. Validate the current physical scene before motion or execution without assuming every machine has an Opentrons-style deck, slots, labware, or row/column coordinates.

This skill validates visible physical state. It does not replace protocol validation, machine telemetry, calibration, interlocks, homing requirements, or operator approval.

When to Use

Use this skill when a PUDA workflow depends on any visually checkable condition, including:

• deck, stage, tray, pan, holder, fixture, cell, vessel, tool, gripper, or target placement
• required-empty or keep-out regions
• addressable wells, tips, channels, samples, bins, or grid positions
• camera-guided alignment, pickup, placement, or inspection
• user requests for vision validation without execution

Use the machine-specific profile selected from bears-machines. Do not force vision validation onto a machine that has no suitable current image source or whose critical state cannot be established visually.
