Counting stock in a large warehouse, especially on high racking, is slow and needs lifts or ladders. Small drones fly the aisles scanning barcodes and tags, checking what is stored where and flagging discrepancies, often working overnight when the floor is clear.
Automated counting is faster and safer than sending people up high and keeps inventory records accurate, which prevents costly errors. The drones must navigate indoors reliably, manage battery life and avoid obstacles, so they suit suitable layouts and defined routines, but where they fit they turn a tedious periodic chore into a routine automatic check.
