How many AMRs do I need for my warehouse?

The required fleet size depends on several parameters:

Calculation Factors:

• Transport Volume: Number of transports per hour/day
• Average Travel Distance: Distance between pick-up and drop-off
• Speed: Typically 1.0-2.0 m/s (loaded), 1.5-2.5 m/s (empty)
• Loading/Unloading Time: 15-60 seconds per stop
• Charging vs. Runtime: Typically 6-8h runtime, 2-4h charging

Rule of Thumb Formula:

Robots = (Transports/h x Cycle Time in Min.) / 60 x 1.3 (safety factor)

Example:

• 40 transports per hour
• Average cycle time: 8 minutes (travel + loading/unloading)
• Calculation: (40 x 8) / 60 x 1.3 = 7 AMRs
• Plus 1-2 reserve for charging cycles = 8-9 AMRs total

Recommendation: Start with a smaller fleet and scale as needed. Most AMR systems are modularly expandable.
