An AMR warehouse robot is an autonomous cart that finds its own way around the warehouse. The picker no longer walks kilometers between racks each shift: shelves and boxes come to their station. The person takes the item, the robot takes the shelf back, and picking productivity grows several-fold. No rails or magnetic tape on the floor are needed.
How it works
The robot is a low platform on drive wheels with lidar and cameras. The lidar spins a laser beam and draws a map of walls, racks and columns; sometimes code markers are stuck to the floor, and a camera underneath checks the robot’s position against them. One type of robot drives under a rack, lifts it whole and brings it to a person. Another takes boxes off shelves with a gripper. A third — a small sorter — carries a parcel to the right chute.
The brain of the warehouse is the fleet management system. It receives orders from the warehouse software, decides which shelf goes to which picker and hands out jobs to hundreds of robots at once. Routes are planned so that machines don’t meet head-on at intersections, and robots with low batteries go off to charge while the others work. Fast-moving goods are kept closer to the stations, slow movers in the far rows.
At the picker’s station there is a screen and cell lights: the shelf pulls up, a light shows which cell to take from and how many items, and a scanner confirms the product. The person does not walk or search — they just pick and put into the order box. Sorters work in a similar way: the parcel goes onto the robot, a scanner reads the address, and the robot carries it to the chute for its destination.
Where it already works
- Vietnam: Viettel Post sorts 1.4 million parcels a day with a fleet of about 200 robots.
- Fulfillment operators and 3PL warehouses that work for marketplaces.
- Distributors with thousands of SKUs and seasonal order peaks.
- Factories: in Vietnam, Phenikaa-X builds AMRs for Samsung.
What to consider
- The budget is not just robots: software and integration add 30–60%, service — $1,000–3,000 a year.
- You need a level floor without thresholds or potholes: the fleet’s speed and reliability depend on it.
- Check the link to the warehouse software (WMS): without it, the robots don’t know what to carry.
- Calculate payback for the peak season and growth, not for an average day.
