How did the invention of the robot change the world?

Answer 1

The invention of robots changed the world because instead of humans having to perform difficult tasks, you could program a robot to do it. Plus, robots have great precision so when they do a task repetitively they will develop better accuracy than a human. They also make life a lot safer for people doing dangerous jobs. Bomb disposal squads can use a robot instead of going to the bomb themselves (they control the robot). And don't forget that robots can go into places that humans can't like Mars (and other planets) and deep ocean depths.
