You might expect crowds of people to block a sidewalk. But what about robots? In August, several food delivery robots caused a traffic jam on a sidewalk in Illinois. The bots were all sent to the same place by mistake.
Robots do many jobs. They put together cars in factories, clean up spills in stores, and more. There are even robot dentists! But are robots the best workers?
Some people say robots are no match for humans. For one thing, robots aren’t good at solving unexpected problems. They also cost a lot of money to build.
But other people think bots make the best employees. Robots can do the same task for hours without getting tired. They also work faster than many humans.
