What is Action Language: Magic Words for Machines

Imagine you have a toy robot that you want to move around, pick up things, or even solve puzzles. Now, to tell the robot what to do, you need a special way of communicating with it. That’s where “Action Language” comes in. Think of Action Language as a secret code you can use to talk to your robot and tell it how to act or make decisions, just like when you play a video game and decide what your character will do next.

Unlike regular languages we use to make computer programs (those are like the instructions to build the robot), Action Language is more about telling the robot how to behave once it’s built. It’s like teaching your robot friend to understand commands such as “move forward,” “grab the toy,” or “think about what to do next,” so it knows how to react in different situations.
