Fleet scheduling for a 12-robot replenishment system
Twelve AMRs, one narrow-aisle warehouse and a WMS that could not be replaced. We made them agree.
The challenge
- The existing WMS had no robot interface and could not be modified by the vendor.
- Narrow aisles caused frequent deadlocks during peak replenishment windows.
- Wi-Fi coverage had gaps that stopped the entire fleet instead of one robot.
What we built
- An integration gateway between WMS and fleet manager, using the WMS's existing database views.
- Zone-based traffic control with reservation and a deadlock-breaking priority rule.
- Per-robot autonomy: a disconnected robot parks safely and rejoins without stopping the fleet.
- Line-side call buttons and a simple status board for warehouse staff.
