Mixture Compatibility System

The system both formulates samples and analyses them to test the cross compatibility of chemical mixtures. The system is split into two distinct robots: preparation and analysis.

An operator generates a list of recipes and loads this onto the system. The preparation robot follows the recipe, dispensing liquids and powders into each sample. If any foam buildup is detected, the system adds an anti-foam to the sample. Prepared samples are finally mixed in a wrist action shaker before being sent to the analysis robot. In the analysis robot, samples are poured through sieves with different mesh sizes to determine good chemical cross compatibility. Good samples pass through all sieve sizes, whereas bad samples clog up the sieves and are flagged as failures. Shaking is also performed to re-mix the sample before pouring through sieves (if required).
