How Does Coordinate Transformations in 2D | Mapping | Robotics 101 Work?

Imagine you're playing with building blocks on a grid, that’s how coordinate transformations work in 2D!

You know how sometimes you move from one room to another, and everything looks different? Like when you go from your bedroom to the kitchen. That's kind of what happens with coordinates, they help us describe where things are, but if we change our point of view, those positions look new.

Say you have a toy box at position (3, 2) on your floor. But then you move to a corner of the room and look back, now that same toy box might seem like it's at (5, 4). That’s a coordinate transformation! You’re still talking about the same toy box, but its position has changed based on where you're standing.

If you draw a map of your room from that corner view, and then switch back to looking from your bedroom, it's like changing maps, the mapping helps you know how things shift when you move around. It’s just like playing hide-and-seek, if you change where you're standing, you need to update your clues!

Coordinate transformations are just smart ways of telling us: “Where is everything now?” based on where we’re looking from! Imagine you're playing with building blocks on a grid, that’s how coordinate transformations work in 2D!
