Barcodes can be hard to find and might be affixed to oddly shaped products, Amazon said in a press release Friday, something robots can't troubleshoot very well.Using pictures of items in Amazon warehouses and training a computer model, the e-commerce giant has developed a camera system that can monitor items flowing one-by-one down conveyor belts to make sure they match their images.Eventually, Amazon's AI experts and roboticists want to combine the technology with robots that identify items while picking them up and turning them around."Solving this problem, so robots can pick up items and process them without needing to find and scan a barcode, is fundamental," said Nontas Antonakos, an applied science manager in Amazon's computer vision group in Berlin.But even infrequent mistakes add up to significant slowdowns when considering just how many items a single warehouse processes in one day."
