In an ordinary store, the shopper does most of the moving. You push the cart, walk to the shelf, pick the product, and carry it toward checkout. Walmart's patents gradually reverse that assumption.

The cart senses the person and helps with the pushing. An unmanned vehicle follows the shopping process. A robot measures shelf stock. Then the products themselves ride on robots toward the shopper. Outside the store, lockers become mobile and drones carry orders through the air.

The ten patents below are US publications. Walmart has deployed real autonomous shelf scanners and drone delivery, but no one-to-one link to the patents covered here was verified, so both are classified only as related.

Drag to pan when zoomed. Use + / − to zoom, 0 to fit, arrow keys to pan, and Alt + arrow keys for the previous or next FIG.

What is it?

When a shopper grips the cart, sensors in the handle can collect pulse, temperature, grip force, and related signals. Cart speed and pushing force can be added to the stream as the shopping trip continues.

If the changing data suggests that the shopper may need assistance, the server can notify an associate. The cart stops being only a basket on wheels and becomes a point where the store senses how the shopping trip is going.

What is it?

The cart harvests energy from wheel rotation and stores it while monitoring pressure at the handle. Under lighter load it can generate power; when forward pressure rises past a threshold, the motor can assist the wheels.

It brings the logic of an electric-assist bicycle into a cart that gets heavier as products are added. Instead of the shopper supplying all the motion, the cart can return some force.

What is it?

An unmanned vehicle moves through the retail environment near the shopper or cart and detects when products are selected. That information can build a digital basket and feed into a point-of-sale process.

The embodiments can include aerial or ground vehicles, and the disclosure even describes robotic manipulation for taking items from shelves. Rather than placing all automation at the exit, the machine travels through the shopping process itself.

In a normal supermarket, people travel to fixed shelves. Here the merchandise itself moves between storage and the customer, and depleted totes can be replaced automatically.

A brush-like pollen applicator extends from the UAV, collects pollen from one flower, and transfers it to another. Sensors can verify that pollen was applied, and the aircraft can return to a docking station for charging.

Here, Walmart's automation moves beyond the store and into the field. Automation is no longer only about moving finished goods; it reaches into how a future product might be grown.

Instead of solving the last meters of drone delivery only in flight software, the patent redesigns the receiving infrastructure too. Once the store can travel through the air, the destination becomes part of the retail machine.

AFTER THE FIGURES

In this future, the shopper is not the only thing moving

The first two ideas still center on a person pushing a cart, but the cart is no longer passive. It measures the shopper and can add physical assistance. Once unmanned vehicles and shelf scanners arrive, the work of moving through the store and gathering information also shifts toward machines.

In the automated-store patent, totes of products can ride on robots toward shoppers instead of shoppers searching every shelf. Then the edge of the store starts moving too. Drones swap tools, automation reaches back to crop pollination, lockers gain wheels, and a carrier vehicle hands an entire locker to a smaller autonomous vehicle.

The final step is the trip to the store itself. If an order can fly to a protected pickup structure, retail is no longer only a building. Across these drawings, Walmart repeatedly treats the store as a connected movement system made from carts, robots, inventory, containers and aircraft.
