Observed Dynamics: In pure Roll Mode, the R-dog achieves 2.8 m/s on flat sidewalk using motorized hub wheels. Upon reaching the steep curb and 4-step residential porch, the chassis switches to articulated quadruped gait, lifting front hips 36px and articulating rear knee linkages to conquer stairs in 6.4 seconds with zero cargo spill.

Grounding: Solves the real-world limitation reported by Fox News: standard wheeled bots stop at curbs, whereas R-dog's wheel-leg articulation delivers parcels directly to the elevated front mat.
