What is a Last-Mile Delivery Robot and How Does It Work?

Last-mile delivery robots are autonomous mobile robots (AMRs) designed to autonomously transport goods from warehouses or distribution centers to their final destinations.

With rising labor costs, increasing logistics demands, and growing expectations for fast delivery, more and more companies are deploying last-mile delivery robots to improve operational efficiency.

This guide provides a detailed overview of the definition, core functions, operating principles, and application scenarios of last-mile delivery robots, as well as how companies can evaluate and select the right solution.

What Is a Last-Mile Delivery Robot?

A last-mile delivery robot is an autonomous mobile robot (AMR) that relies on sensors, AI navigation systems, and fleet management software to enable fully automated delivery from the warehouse to the customer. They are primarily used on campuses, in industrial parks, in hospitals, in warehouses, and in residential communities to address the most costly aspect of logistics—last-mile delivery (which accounts for over 50% of total logistics costs).

Core functions of last-mile delivery robots:

• Autonomous Navigation: The robot can navigate independently in complex environments.
• Intelligent Obstacle Avoidance: Real-time detection of pedestrians, vehicles, and obstacles to ensure safe maneuvering.
• Task Scheduling: Optimizes routes and manages the coordination of multiple robots.
• Secure Delivery: Supports contactless delivery to ensure the safety of goods.

How Do Last-Mile Delivery Robots Work?

Last-mile delivery robots combine intelligent software with high-precision hardware to enable automated delivery from the warehouse to the end user. Here is the workflow and technical principles:

Step 1 — Task Generation and Scheduling System

1. System Integration

The robot retrieves order information by integrating in real time with the Warehouse Management System (WMS) or Enterprise Resource Planning (ERP) system.

2. Order Trigger

When a user places an order, the system automatically generates a delivery task and assigns it to an available robot.

3. Task Scheduling

Scheduling algorithms consider distance, robot status, and traffic conditions to plan the optimal route and task priority for each robot.

Leveraging cloud-based scheduling and big data analytics algorithms, the system completes task assignments in the shortest possible time, improving delivery efficiency and response speed.

Step 2 — Autonomous Navigation and Path Planning

1. SLAM Mapping

The robot uses LiDAR, cameras, and other sensors to scan the environment in real time and build indoor and outdoor maps.

2. Dynamic Obstacle Avoidance

The robot can identify pedestrians, vehicles, and obstacles, and automatically adjust its route.

3. Multi-robot Coordination

During peak delivery periods, the system coordinates multiple robots to avoid collisions and path conflicts.

Simultaneous Localization and Mapping (SLAM) algorithms enable robots to navigate autonomously in unknown environments, combined with path planning algorithms such as Dijkstra’s to achieve efficient movement.

Step 3 — Automatic Loading and Transport

1. Automatic Docking

The robot can precisely approach warehouse shipping ports or loading docks to perform automatic loading.

2. Pallet/Box Handling

Robotic arms or track systems safely load goods into the cargo compartment, ensuring safe transport.

3. Technical Principle

Through motor-driven mechanisms and sensor feedback control, the loading process is precise and reliable, minimizing the risk of cargo damage.

Step 4 — Arrival at Destination and Secure Delivery

1. Automatic Door Opening

The robot can enter a residence or office via QR code scanning, Bluetooth, or remote commands.

2. Elevator Integration

In multi-story buildings, the robot communicates with the elevator system to move automatically between floors.

3. Security Verification

During delivery, the recipient’s identity can be verified via facial recognition, a password, or a QR code.

By combining IoT (Internet of Things) communication and multi-factor authentication technologies, we ensure that goods are delivered accurately and securely to the user.

Step 5 — Return to Charge and Standby

1. Automatic Charging

After completing a delivery, the robot automatically returns to the charging station to recharge.

2. Battery Management

The system monitors battery status in real time and intelligently plans the next delivery task.

The Intelligent Battery Management System (BMS) ensures safe charging and discharging, optimizes the robot’s operational cycle, and enhances availability and reliability.

Last-mile Delivery Robot Workflow

Order Generation → Task Dispatch → Autonomous Navigation → Loading and Transport → Delivery to Destination → Return for Charging → Standby

Through this process, last-mile delivery robots have achieved full automation—from order generation to safe delivery, self-maintenance, and charging. This not only improves delivery efficiency but also significantly reduces last-mile delivery costs.
