How Do Robots Know What to Do?

Imagine you're playing with a toy robot. It moves around, avoids obstacles, and even follows you! But how does it know what to do? Well, just like you follow instructions from someone else, robots use instructions called code. They also have special tools called sensors, which help them see, hear, or feel the world around them. When they get information from their sensors, they decide what action to take, like a robot that moves forward when it sees light and stops when it hits something.
