Micromanipulation (e.g., human/plant cell handling) often demands expensive, calibrated equipment and controlled environment. This project delivered a portable, calibration‑less workflow: detect–focus–track–servo that works on low‑cost microscopes and compact microstages. Reported outcomes include sub‑pixel tool‑tip localisation, 95.3% autonomous refocusing toward the focal plane after intentional blur, <1‑pixel average visual‑servo error, and 97.7% cell detection accuracy, proving that high‑precision automation can travel beyond traditional labs.
To keep target tracking uninterrupted in uncertain environments (partial occlusions, lighting changes, busy backgrounds), the solution added confidence‑based hybrid tracking that fuses motion‑cue feature detection with template matching; the fusion maintained sub‑pixel mean error where a single template tracker degraded to 1.53-2.08 pixels under the same conditions. A self‑initialisation and recovery mechanism then automatically re‑localises the tool when interaction or occlusion disrupts tracking and adapts the template to the tool’s new appearance, improving localisation from >50% to <10% of specimen size and sustaining uninterrupted tracking without manual intervention. Together, these improvements have the potential to prevent control dropouts that cause failed manipulations.
A calibration-less portable system resilient in uncertainty in industry settings often means fewer failed attempts, higher tracking accuracy, and shorter setup/training, reducing preparation time and technician effort. The approach enables plug‑and‑play micromanipulation for field studies, point‑of‑care diagnostics, and teaching labs, with clear potential to be packaged as commercial toolkits that save time and cost while widening access to precise microscopic work.
