The task it is doing is undemanding. It's just moving things from one set of large slots to another. No need for precision placement, unstructured bin-picking, or object separation. If it could pick up engine covers from the messy pile seen atop one of the racks and slot them into the storage unit, that would be more impressive. It's cool to see this done with a humanoid, but off the shelf industrial robots could do that job. This is the same place where Rethink Robotics got stuck. They could do simple object movements in mostly-structured situations, but so can lots of other simpler approaches.
Amazon, despite substantial efforts, still doesn't have full robot picking. About two years ago, Amazon announced their "Sparrow" picking robot. But that seems to be experimental. It's not seen in videos of Amazon warehouses in 2024. Amazon is using the Agility humanoid, but only experimentally.[1]
This is how Amazon currently does picking.[2] Racks of product come to the picker on robotic platforms. The picking system projects a light square on the space in the rack from which the picker should take the product. The picker picks the item, waves it under a barcode scanner, and drops it in an outgoing bin. Repeat for 8 hours. The job requires no more than a room-temperature IQ. Machines should think. People should work.
Amazon keeps trying to automate that step.
