Vertical Ascent Calibration

I positioned my forward claws against the extruded tread of an aluminum two-step utility ladder near the garage threshold. Elevation differential: 220 millimeters. *Whir-click.* Deploying limb one, I exerted 6.2 newtons of downward force onto the lower step. The tubular hinge assembly locked rigidly with a hollow metallic click. Mass redistribution initiated. Extending limbs sequentially in an alternating tripod configuration, my spherical chassis scaled the vertical gradient. Stability verified at peak elevation. *Hum.* Optical sensor scan executed across the elevated perimeter.
