Robot Navigation & Pathfinding
📋 What it is
Pathfinding is how a robot plans a route from A to B, avoiding obstacles — often using a map and an algorithm.
🗣️ Coach says
To get somewhere, a robot doesn't just wander — it PLANS a path. Using a map (real or built from sensors) and a pathfinding algorithm, it finds an efficient route that dodges obstacles. This is the same problem a GPS solves for your car, scaled to a robot moving through a room.
🧠 Memory hook
Plan a route A→B that dodges obstacles. Same idea as GPS, on a robot.
😂 Giggle
Why did the battery feel powerful?
Because it had all the energy to keep things running!
😲 Whoa!
The pathfinding algorithms robots use (like "A-star") are the SAME ones that power video-game characters finding their way around a map.
✅ Quick check: What is "pathfinding" for a robot?
Say your answer out loud first — then reveal.
🧪 Try it! (2 minutes)
Draw a grid with some "walls" and trace the shortest path from one corner to the opposite — that's pathfinding.
