From Eat Me Daily: Humans used to stack the pancakes by hand, but in a bid to reduce labor costs, HoneyTop Pancakes switched to a robot solution from ABB Robotics. In their machine, pancakes on a conveyor belt are fed into an enclosure where the insect-like Flexpicker robots grab and stack the pancakes at a truly astonishing speed, at over 400 per minute! Using high-resolution cameras, the robots can recognize overlapping pancakes, and their crazy AI programming includes a "buffer system" in which the robots can save some pancakes for later on a shelf to keep up with all of them whizzing by. Has to be seen to be believed.
Apparently, the Flexpicker is the world's fastest industrial robot, and it's not limited to pancakes — it's used to sort all kinds of foodstuffs like sausages, muffins, and croissants.
