Ahold USA is currently trialing a robot in a Giant Food Store. Its job is to detect dangers and then ask for assistance. He can also point out empty shelves and check prices.
The robot called Marty freely moves throughout the store. He will keep an eye on the floor, to make sure nothing is spilled or that there are no other dangers. If that is the case, he will stop and ask for assistance from one of the employees so that they can fix the issue.
He also keeps an eye on the shelves and when a particular product is no longer available, he will pass that on. If it is still in stock, he will create a report informing employees which items to resupply. He will also look at all the prices and compare those with the prices in the cash register system. If there are discrepancies, he will generate another report so that employees can fix the problem.
