Well, they are in factories, warehouses, orchards, hospitals and even homes. They may look like large mechanical arms, like the ones in car manufacturing plants, welding, gluing and painting car parts. Or they may look like tiny cameras, like the ones in hospitals, attached to thin hair-like tubes, entering our intestines and arteries to check them out for problems. Some robots look like flat round discs, working in homes and offices, buzzing around and cleaning floors at night when everyone is asleep. Some look like small wheeled vehicles, going into war zones, finding dangerous landmines, or rolling across the surfaces of the moon or Mars, taking pictures and collecting samples to send to

scientists back
