At the facility outside Berlin, inside a fenced-off room larger than a football field, robots have long been used to fetch large boxes from shelves several stories high.Warehouses are already highly automated.Engineers can program a robot to perform the same motion over and over again.The boxes are uniform and a robot can pick them up with the same motion every time.Programming a robotic arm to deal with every situation, one rule at a time was impossible before.
However, Covariant, which is working with Knapp, built software that could learn through trial and error.The robot could continue to learn as it sorted through items it had never seen before.
Therefore, inside a warehouse on the outskirts of Berlin, a long line of bluecratesmoved down aconveyorbelt, carrying light switches,socketsand other electrical parts.As they came to a stop, a robot used three suction cups at the end of its long arm sift through parts with surprising speed and accuracy.The robot can pick and sort more than 10,000 different items, and it does this with more than 99% accuracy.
Because the online retail business is growing so quickly and most companies will be slow to adopt the latest robotic technologies, economists believe the advances will not cut into the overall number of jobs anytime soon.But the engineers building these technologies admit that at some point most warehouse tasks will be done by machines.Human workers will need to find other things to do.
