Drones in Distribution: Counting Inventory

We can all imagine drones moving boxes in the distribution center. However, there are a couple of reasons that make it difficult to move boxes today. That being said, another scenario offers even a more compelling advantage: inventory control. Of course, a few technological hurdles need to be overcome for this idea to be really feasible. Today, the payload for a drone is limited. To increase the payload, the drones need more motors and propellers, which increases the size of the drone significantly.

This size increase also its battery efficiency. After installing this many propellers and battery, the flight time on the drone might only be 15 to 20 minutes with a payload of maximum 10 to 15 pounds. In order to keep the drones operating, there have to be recharging stations where the drones have to be sent every 15 minutes. Again fast charging technology will help here, but that technology is not fully ready yet.

So this significantly reduces the feasibility of drone deployment, except in distribution centers that move small items. Electronic components might be one example. Also small electronics products, including smart watches or fitness trackers. Of course, all these in E-commerce customer order fulfillment scenarios.

The second area where drones offer a lot more opportunity and better bang for the buck is for inventory counting. There are two approaches to leveraging drones for inventory count.

The first approach is using radio-frequency identification (RFID tags).  In this scenario, each unit of every SKU would need an RFID tags in it and then also the locations that hold them (any type of location, such as pallet reserve, case reserve, case pick, active, etc.). The drone would take a flight path that covers all the locations, which would mean that the drone would have to fly at different altitudes to cover all levels of racking and then read the tags that are in that vicinity including the parent RFID tags associated with the locations.

Further, the methodology followed for counting would need to be slightly different because of the use of RFID tags for counting. The distribution center needs to be divided into zones and inventory needs to be associated to the zone and then compared on a weekly basis or a daily basis at this zone level rather than counting at the bin level. This approach is slightly different compared to the most popular warehouse management systems (WMS) that are used today, which count the inventory at the bin or at location level.

The second approach would be to scan the warehouse locations using a camera and then convert the images into inventory count. This approach would work for pallet reserve, single SKU case reserve and even for case pick locations. It would not work for active locations because the units within the active location need to be moved around during counting to see all the units. This means the number of tiers for a pallet and the number of cases within a tier will need to be established at the item master level and also the pallets and cases will have to be built following those standards. Also the algorithm needs to be sophisticated to translate the rectangular boxes that appear in the images to actual box count.

In Command Wearable is one another technology that can be integrated with the drones. this ruggedized consumer electronic device for use in enterprise environments as an alternative to the rugged wearable computers like Motorola WT4000 and Honeywell LXE HX2. In Command Wearable has a consumer electronic device, a proprietary ergonomic rugged enclosure, and intuitive set of apps to enable the consumer device to be used in warehouse and distribution environments. The first generation of In Command Wearable uses Apple iPod Touch 5 as the core-computing device paired with a Bluetooth ring scanner for data capture. By integrating In Command devices with drones the computation of inventory from images can be done more easily leveraging the sophisticated cameras.

About:
Puga Sankara is the Founder, CEO of Smart Gladiator LLC. Smart Gladiator designs, builds, and delivers market-leading mobile technology for retailers, distributors, and 3PL service providers. So far, Smart Gladiator LoadProof has been used to ship, receive, and scan more than 100 million boxes. SG LoadProof is a patent pending Centralized Enterprise Photo/Video Document System on Cloud for Supply Chain. SG LP is built on the fact that photos & videos are vital docs as important as POs/SOs/Legal Contracts/Fulfillment Orders that reside in ERP/WMS/TMS systems, that serve as compelling, conclusive, unequivocal proof of crucial, critical, vital operations executed in Supply Chain within/across orgs when fulfilling customer orders as well as meeting contractual obligations between orgs as merchandise is transferred between different parties that partake in Supply Chain functions & operations. And these photos/videos data should not be stored in someone’s Smartphone or Email Inbox or in their personal/work Computer, but should be stored in a Centralized Enterprise system, where such data can be pushed into super-fast, stored securely, accessible to all stake holders (CFO/Sales Reps/Customer Support/AR/AP) in an org, as well as facilitates super-fast retrieval/sharing. LP is an Enterprise System of record for Photo/Video docs & is as important as an ERP which is an enterprise system of record for POs, SOs, Legal Contracts between parties etc. that have huge legal ramifications, also as important as a WMS (Warehouse Management System) that hold indispensable shipment & fulfillment data on orders. Like how Instagram, Facebook, Snapchat etc. have evolved into social media platforms/systems that enable individuals to showcase their beauty/pretty clothes/lovely cosmetics/hep coolness etc., LoadProof is an Enterprise system that holds similar photos/videos, but for a different reason, not for show off, but to serve as compelling, conclusive, unequivocal & indisputable system of record and proof that can be presented even in the court of law, when there is a dispute between parties while they execute many facets of the Supply Chain functions & operations. SG LoadProof is also an Enterprise System of Record for Photos, videos and any other digital documents for your Supply Chain Network. A system of record (SOR) or source system of record (SSoR) is a data management term for an information storage system (commonly implemented on a computer system running a database management system) that is the authoritative data source for a given data element or piece of information. The need to identify systems of record can become acute in organizations where management information systems have been built by taking output data from multiple source systems, re-processing this data, and then re-presenting the result for new business use. In these cases, multiple information systems may disagree about the same piece of information. These disagreements may stem from semantic differences, differences in opinion, use of different sources, and differences in the timing of the extract, transform, and load processes that create the data they report against, or may simply be the result of bugs. The integrity and validity of any data set is open to question when there is no traceable connection to a good source, such as a known System of Record. Where the integrity of the data is vital, if there is an agreed system of record, the data element must either be linked to, or extracted directly from it. In other cases, the provenance and estimated data quality should be documented. The “system of record” approach is a good fit for environments where both: 1. there is a single authority over all data consumers, and 2. all consumers have similar needs Here, LoadProof is the System of Record for pictures and videos for all the entities in Supply chain who uses pictures and videos to track using any Supply Chain System infrastructure. 1. LoadProof provides accurate, thorough, complete, and latest information in pictures and videos related to any entity in the Supply chain that is tracked. 2. LoadProof is the single authority on pictures and videos related to any entity in the Supply Chain that is tracked 3. LoadProof doesn’t let any external system to copy the records being stored in it, which eliminates the data being duplicated in multiple places to preserve the data integrity and credibility. 4. LoadProof has a secured login procedure which lets only users with select level access to view the data and modify the records which helps in maintaining LoadProof is becoming the Industry Standard System for Photo & Video Docs for Supply Chain Smart Gladiator is located in ATDC - Advanced Tech Dev Center (tech Incubator) in Georgia Institute of Tech.
