Wally Challenge Arena: Fire-Running · Maze Adventure · Speed Duel

🏆 Wally Challenge Arena — Three Competition Tracks

🔥 Track 1: Fire-Running

A 200×80cm corridor full of obstacles (Wally must go from start to finish without touching any). Scoring: time + collisions. Key tech: ultrasonic avoidance + precise steering.

🌀 Track 2: Maze Adventure

Find the exit in a 150×150cm maze. Use the left-hand / right-hand rule, Flood Fill, or A* pathfinding. Key tech: line-following + infrared + path algorithms.

🏎️ Track 3: Speed Duel

Two Wallys race on a U-shaped track back to the finish. Key tech: PID line-following + speed optimization + corner strategy.

"The key to winning is not the highest speed but the most stable strategy. A program that reliably completes 80% of the route is more competitive than one that is occasionally perfect but often fails."
