Lesson 1 of 3
Signposts you can see
A landmark is something easy to spot: a red post box, a tall slide, a painted mural. When every corner looks alike, landmarks tell you which corner you reached.
Directions can say turn left at the fountain, then forward until the bike rack. The landmark splits a long path into chunks your brain can hold.
Follow the step-flow animation. Watch a route broken into legs separated by landmark pictures.
Lesson 2 of 3
Choosing good landmarks
A good landmark is unique on your route. Do not pick another plain bush if there are twenty bushes. Pick the giant clock or the blue bridge.
Landmarks must stay put. A parked car might leave. A statue usually stays. Programs use fixed markers on grids for the same reason.
If a friend gets lost, ask which landmark they last saw. That one clue narrows where the wrong turn happened.
Lesson 3 of 3
Landmarks on grids
Grid maps use symbols like trees and rocks as landmarks even when they also block paths. They anchor your mental picture.
When you plan in the robot lab, say aloud: after the tree, turn right. It links the picture to the command list.
Next you will plan a full route from start to goal using every skill so far.
