There's a good chance that something you've bought online has been in the hands of a " picker". These are the workers in warehouses (仓库) who pick, pack and ship all those things we ordered.

At Amazon and other companies, they're working side by side with robots. Experts say while the robots are replacing some human workers, the machines aren't quite ready to take over completely.

When a robot finds its storage unit,' it slides underneath, lifts it up and then delivers it to a worker they're called pickers. On a recent day, the computer told a picker to grab what looked like a fantasy board （#t 3#)game. The picker found it, packed it and placed it on the conveyer belt.

"In a traditional fulfillment center where the workers would walk to the different items, it can take hours to fulfill a customer order," Robinson says.

Now, with the help of robots, that task takes minutes and fewer humans.

So is this a sign that we're entering a new industrial revolution?

" It's definitely going to take over a lot of jobs ", says Karen Myers, a scientist at SRI, one of Silicon V alley's oldest research centers.

At the same time, she says, " We're running against the limits of technology. " Take the picker at the Amazon fulfillment center for example. Myers says those skills prove to be uniquely human.

"Our fingers are incredibly flexible and the current generation of robotic operators are getting much, much better," she says. "But they're just not quite there yet."

There's also the robot's brain.

Remember that board game the Amazon worker was looking for? She could barely see the box when it was filled into the storage bin——but she could tell it was a board game. Robots can't do that.

Technologists say that, increasingly, humans will work side by side with robots——instead of robots working alone.

Amazon says robots and humans enabled the Tracy warehouse to fulfill customer orders faster. That means more customers and more human workers.

When we were played basketball yesterday, a quarrel about a ball happens between Li Lei and Li Ming. Thank to the classmates there, the quarrel stopped after it developed into a fight.

We had our P.

Glad to hear from you. I'd like to tell you something about the Qingming Festival.

Best wishes !

Yours ,
