Multi-Sensor Recycling Sorter

Watch a robotic picker sort a mixed conveyor stream of visually similar materials. Compare vision-only sorting — which confuses look-alike plastics — against multi-sensor NIR spectroscopy, which reads true chemical composition and keeps every bin pure.

A robotic picker arm lifts items off a moving conveyor and sorts them into Plastics, Metal, Paper and Reject bins. Some clear bottles are PET (recyclable plastic) and some are visually identical PVC (a contaminant that must be rejected) — a purely visual classifier cannot tell them apart and misroutes the look-alikes, while a multi-sensor picker fires a quick NIR scan to read each item's real chemical composition before it picks. Toggle between the two sorting methods and watch the per-bin purity and contamination counters diverge.

⚙ Under the hood

Watch a robotic picker arm sort a mixed conveyor stream where some clear plastic bottles are PET and some are visually identical PVC. Toggle vision-only sorting, which can't tell the look-alikes apart and contaminates the plastics bin, against multi-sensor NIR spectroscopy, which reads each item's true chemical composition before it picks, with live per-bin purity and a cumulative contamination-events counter for both methods.
