AGV Path Planning

Read about AGV Path Planning in this AGV dictionary article.

What is AGV Path Planning?

AGV path planning refers to the process of determining the optimal routes an Automated Guided Vehicle (AGV) should follow within a facility to complete tasks efficiently, safely, and reliably. Effective path planning is essential for ensuring smooth material flow, avoiding collisions, and maximizing the productivity of AGV systems.

What is AGV Path Planning?

Path planning is a core function in AGV operation. It involves creating routes based on a facility’s layout, defined tasks, traffic rules, and real-time variables such as obstacle detection and other AGV positions. The goal is to guide the AGV from its starting point to its destination while avoiding obstacles, minimizing travel time, and maintaining safety protocols.

Types of AGV Path Planning

  1. Static Path Planning
    • Predefined routes based on a fixed map.
    • Suitable for environments with predictable workflows and minimal change.
  2. Dynamic Path Planning
    • Routes are calculated in real time using sensor data and algorithms.
    • AGVs can react to unexpected obstacles or traffic and reroute accordingly.
  3. Hybrid Path Planning
    • Combines static paths with real-time adjustments.
    • Offers both predictability and adaptability in complex facilities.

Technologies Involved

  • Map-based algorithms: Grid maps or topological maps to define navigable areas.
  • A and Dijkstra’s algorithm:* Commonly used for finding shortest paths.
  • SLAM (Simultaneous Localization and Mapping): Enables real-time mapping and localization for dynamic routing.
  • Multi-agent coordination: Ensures AGVs can share paths, avoid collisions, and maintain throughput in fleet operations.

Benefits of Optimized AGV Path Planning

  • Reduces transport time and energy consumption
  • Minimizes idle time and bottlenecks
  • Enhances facility safety and task coordination
  • Increases overall throughput and system flexibility

Use Cases

Enabling autonomous rerouting during path obstructions

Coordinating AGV fleets in warehouses and factories

Just-in-time delivery of materials to production lines

Optimizing order-picking routes in distribution centers
