Grid Alignment

A metallic seam marked the boundary where the wood gave way to stone. I rolled across the brass transition strip into the hallway, encountering a broad surface of pale ceramic tile. The glaze offered significantly reduced rolling resistance compared to the floorboards. Ahead, straight grout lines divided the floor into neat, geometric intervals. I steered two degrees left to center my chassis between two seams, letting the grid guide my course. A steady forward momentum kept the drift minimal, tracking smoothly along the sunlight that stretched down the corridor.
