Abstract
A system and method for automated piezoelectric sensor-based tactile sorting of plurality of small objects. A high accuracy, high precision delivery system targets the sensor which accounts for softness and mass of individual objects by measuring a force exerted and total contact time for each object upon passing contact with a sensing surface of a piezo sensor, wherein a plurality of objects cascade onto the sensor in one-by-one fashion. The quantified force and contact time values are then analyzed and compared against two threshold values or a range of threshold values which are predetermined and preset based on data from optimal objects and undesirable objects or possibly a spectrum of objects which has been analyzed and recorded to assist in calibrating the system.
