(FOX 13) - Move over, R2-D2. Robots are coming to Walmart.
Dozens of stores already have robots roaming the aisles, doing everything from retrieving items and scanning shelves to cleaning the floor.
At Walmart, they're known as Smart Sidekicks for employees.
The robots can reportedly scan grocery shelves three times as fast as people can. And they can check for out-of-stock items, mislabeled shelf tags, and incorrect prices.
Walmart is planning an aggressive expansion of robotic technology this year, including more than 1,200 unloaders that'll automatically scan and sort items from trucks.
They say the new technology can free employees up to focus more on selling merchandise and serving customers.
