Click the squares to toggle them from air to wall. After you’ve made the maze, the robot (which has a rather low IQ) will try to get to the yellow square. After the robot has reached the yellow square, this project shows you the path. ============ Disclaimer: The robot will get stuck really easily.
I can’t remember which project it exactly is, but one day I searched “pathfinding ai”. And saw one like this one. You can see a bunch of projects that are way better there. https://scratch.mit.edu/search/projects?q=Path%20finding%20ai
