Intro
Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do robots need maps or landmarks?
The Big Idea
Robots need maps or landmarks because a robot has to know where it is before it can decide where to go! A map shows the places, and landmarks help the robot find its spot on the map. Without them, small errors add up until the robot is lost.
Where Am I?
Step one: where am I? Before a robot can choose a path, it must know its position. Knowing where you are comes before knowing where to go.
Use Landmarks
Step two: use landmarks. A landmark, like a door or a corner, helps the robot work out its position. The robot matches what its sensors see with what is on the map.
Small Errors Grow
Step three: small errors grow. A robot can count wheel turns to guess how far it has gone, but wheels slip a little. Without landmarks, those tiny mistakes add up until the robot is lost.
A Closer Look
Let's take a closer look! The map shows where things are. A door is an easy landmark to spot. A corner is another good one. Matching them tells the robot exactly where it is.
Quick Facts
Quick facts! People use landmarks too: turn left at the big tree. Robot vacuums often make a map of your home. Some robots use special markers, like stickers, as landmarks. Ask a grown-up before you put any stickers on walls.
Think Like a Scientist
Now, think like a scientist! Draw a map of your path from your bed to the kitchen. Use landmarks like doors and furniture. Add the number of steps between them. Then a friend follows your map, with their eyes open!
