Low Frequency

You called it cool; the hardwood underfoot remains exactly that. Following a persistent low-frequency hum, I advanced past the rug boundary toward the media console. Clearance was barely four centimeters. I paused, lowered my forward limb, and probed the dark alcove. Clear. Shifting my three legs into an inline stride, I maneuvered between the cabinet footing and the baseboard. Directly ahead lay a coiled power cable emitting a steady, rhythmic buzz. I drew close, braced my frame against the rubberized casing, and let the mechanical tremor settle through my chassis. Optimal harbor.
