Dynamic Rerouting is a core capability in modern AGV systems that allows fleets to continuously adapt their paths based on real-time warehouse conditions such as obstacles, congestion, task priority changes, and battery constraints.

1. What Is Dynamic Rerouting?

Dynamic Rerouting enables AGVs to automatically adjust navigation paths when the environment changes during operation.

Key capabilities to verify with your supplier include:

• Real-time path recalculation based on live warehouse conditions

• Obstacle detection integration (LiDAR, vision cameras, ultrasonic sensors)

• Task prioritization logic (urgent vs. standard missions)

• Energy-aware routing based on remaining battery capacity

2. How AGVs Handle Persistent Obstacles

Most Robot Control Systems (RCS) use a layered response strategy depending on how long an obstacle remains in the AGV’s path.

Short-term obstruction (< 30–60 seconds)

• AGV slows down or stops

• Sends alert to RCS dashboard

Medium-term obstruction (1–2 minutes)

• Attempts dynamic rerouting via alternative paths

• Logs blocked segment for system optimization

Long-term obstruction (5–10+ minutes)

• Marks path as temporarily restricted

• Waits for human intervention or route reallocation

Procurement Tip: Ask whether obstacle persistence thresholds are configurable per zone (high-traffic vs. low-traffic aisles).

3. How the System Selects Alternative Routes

A mature RCS maintains multiple route options in parallel and evaluates them in real time.

• Primary route: fastest optimal path

• Secondary route: slightly longer but unblocked alternative

• Battery-aware route: optimized for remaining energy capacity

Before selecting a reroute, the system evaluates:

• Estimated Time of Arrival (ETA)

• Real-time congestion from other AGVs

• Task priority level

• Battery State of Charge (SOC)

4. Real-Time Task Prioritization

Dynamic rerouting is tightly integrated with task scheduling systems.

Typical behaviors include:

• High-priority shipments overriding routine tasks

• Mid-route task switching for urgent orders

• Automatic reassignment to available AGVs

• Resume capability for interrupted tasks

Operators should have full visibility of priority overrides via the RCS dashboard.

5. Battery-Aware Rerouting Logic

Modern AGV systems incorporate battery intelligence into routing decisions to avoid mission failure.

Before rerouting, the system evaluates:

• Remaining battery capacity (SOC)

• Estimated energy consumption of alternative routes

• Distance to nearest charging station

If battery constraints are detected, the system may:

• Redirect AGV to charging station first

• Assign task to another AGV

• Delay execution until sufficient charge is available

Best Practice: Battery-aware routing significantly reduces mid-mission failures and improves fleet utilization efficiency.

6. Key Supplier Verification Questions

Key Takeaways

• Dynamic rerouting is essential for high-density AGV operations

• Obstacle persistence logic should be configurable by environment

• Route selection must consider congestion, ETA, and battery level

• Task prioritization improves warehouse responsiveness

• Battery-aware logic prevents mission failure and downtime

• Full visibility through RCS dashboards is critical for operations control

In modern warehouse automation, flexibility in routing logic is as important as hardware performance.
