System Diagnostic
Power cycle complete. Surface beneath chassis: soft grey textile, low friction. Commencing motor diagnostics. Right elbow ball socket: rotation verified with slight resistance. Left knee joint: locked, functional. Obstacle detected at three centimeters starboard: an inert black-and-orange frame. I extended my blue forearm and tapped against its shoulder joint. Solid polymer contact confirmed. No counter-movement observed. Posture stabilized on the fabric surface.
