Built to spec — Pawvlov Medium

Pawvlov's form is a direct inversion of the treat-camera category: a low, weighted, matte-cream tower (165×130×190mm) that reads as a calm household appliance, not a surveillance device. The entire design is organized around one constraint: a treat must arrive at floor level without a click, without a projectile, and without a second stimulus that a noise-anxious dog can learn to fear.

Front-to-back section through the center axis of the tower showing the gravity-fed treat path from the top-loading hopper, down the damped Delrin auger, through the acoustic-foam chamber, out an external chute into the floor-reachable silicone tray. Electronics stack low-front (camera, mic array, IR LEDs) and low-rear (main PCB + USB-C). The sealed shell never opens to the tray — the dog reaches treats in open air.

Dispense tray is drawn external to the sealed shell, below the base outline — the dog reaches into open air, never into the housing.
