The most efficient solution uses a Depth-First Search (DFS) with backtracking . By treating the room as a graph, the robot explores every reachable branch (cell), marks it as visited in its internal "relative" coordinate system, and backtracks to its previous state once it hits a wall. 2. Real-World Engineering: From DFS to SLAM

While the algorithm uses simple grid logic, real robots like those from Ecovacs or iRobot use . Robot-Room-Cleaner.rar
