## TL;DR
AI robots run the world's warehouses -- 750,000+ at Amazon alone, moving goods, picking orders, and sorting packages. From autonomous forklifts to AI-powered bin-picking arms, warehouse robotics transforms fulfillment from labor-intensive to lights-out automation.

## Core Explanation
Warehouse robotics: (1) Transport -- AMRs (Autonomous Mobile Robots) navigate via SLAM + sensor fusion (LiDAR, cameras, IMU). Avoid obstacles, humans, and each other dynamically. Payload: 500-1500kg; (2) Picking -- robotic arms with CV for item identification, grasp planning, and quality checking. Sparrow (Amazon, 2022) handles individual item picking; (3) Storage -- goods-to-person systems (AutoStore) bring inventory bins to pick stations; (4) Sortation -- AI robots sort packages by destination with conveyor-belt integration.

## Detailed Analysis
Amazon Proteus (2022): first fully autonomous Amazon robot designed to work alongside humans. Uses perception + safety-rated sensors. Cardinal (2022): robotic arm for package handling, lifting up to 50lbs. Sparrow (2022): individual item picking from totes -- the hardest robotics problem. Computer vision identifies items in clutter; grasp planner selects approach; suction gripper executes. 65% of Amazon orders now touched by robotics. Locus Robotics: AMRs for order picking. Human pickers stay in zone; robot navigates to next pick location. Covariant AI: universal picking AI for any item. Brain: transformer-based model trained on diverse warehouse item data. AutoStore: cube storage with robots on top grid, digging bins and delivering to ports. 1,400+ installations globally. Key challenge: general-purpose picking. Items vary enormously (size, shape, weight, fragility, packaging). The dream: any item, any grip, first attempt.
