Design and Automated Control of the Electron Microscopy Proteomic Organellar Preparation Robot
Bibliographic record
Abstract
The Electron Microscopy Proteomic Organellar Preparation (EMPOP) robot is a tool for high-throughput preparation of subcellular fraction samples for electron microscopic identification. It provides a means of validating subcellular sample purity and confirming protein localization needed for organellar proteomics. The device handles all chemical and mechanical manipulations required to prepare organelles for electron microscopic examination. It has a modular, integrated design that supports automated filtration, chemical processing, delivery, and embedding of up to 96 subcellular fraction samples in parallel. Subcellular fraction specimens are extremely fragile. Consequently, the system was designed as a single unit to minimize mechanical stress on the samples by integrating a core mechanism, composed of four modular plates, and five support subsystems: (1) a cooling platform, (2) an automated fluid handling subsystem, (3) an electromagnetic arm, (4) a plate transfer platform, and (5) a 5-axis motion control system (X, Y, Z, θ, ø). System control is fully automated to provide standardized, reproducible subcellular fraction sample processing while maintaining flexibility for adjustment and recall of instrumentation and process operational parameters. To achieve this, the control software was built on two coordinated levels: (1) a user interface for system testing, calibration, setup, and process monitoring and (2) low-level real-time control routines. The EMPOP robot provides, for the first time, massive, parallel electron microscopic screening and quantitative analysis of subcellular and protein targets necessary for high-throughput proteomics.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
