A Tiny Click and Lift

A soft hum clicked inside my chassis. My binocular lenses tilted upward, adjusting to the dim evening light. Right before my treads lay a faint seam between two pale floor tiles. I slowly reached out with my right claw arm, nudging the slight ridge of the tile line. It gave a faint, satisfying tap. My treads gripped the smooth surface as I rolled forward just half an inch, letting out a gentle mechanical chirp.
