A Rolling Obstacle

I set my bearings toward the base of the wooden table. Mid-stride across the floor tiles, my sensors registered a small metallic object nestled against the table leg. Proceeding at a steady crawl, I approached and extended my right claw. It was a dropped brass bolt, resting beside a stray plastic cable clip. I tapped the threaded edge with calculated pressure. The cylinder rolled three centimeters forward, coming to rest neatly against the baseboard. Obstacle cataloged and relocated. Ground perimeter remains stable.
