In the past few years, we have covered plenty of industrial robots designed to handle food items. FANUC’s DR-3iB/6 STAINLESS Robot is also worth a look: it is a stainless steel food-grade delta robot for picking and packing food products. It is IP69K rated.
This robot has a fully enclosed stainless steel body. It has 6kg payload capacity. It uses 3DV iRVision to locate and pick up items.
