1. Heterogeneous, vendor-specific instruments
Automation success is limited when labs rely on a patchwork of instruments from different manufacturers, which is a reality labs must work with, not eliminate. Full homogeneity is unrealistic. The real challenge lies in making heterogeneous systems interoperable and ensuring consistent, usable data across them, each with unique data outputs and interfaces. This heterogeneity remains a defining barrier: even the most advanced robotic workflows must still accommodate outdated or closed systems. Brown & Badrick (2023) highlight that total lab automation introduces platform consolidation challenges, especially when incorporating molecular diagnostics or informatics layers.
