The US Patent and Trademark Office have publicized Walmart’s application for patent dubbed as: Systems, Devices, and Methods for In-Field Authenticating of Autonomous Robots.
In the latest patent, Walmart’s system will revolve around the authentication of independent electronic devices to create a drone delivery network. A drone robot will bring an order to the specified location where a second drone will be waiting. Both the first and second drones will send each other authentication signals by means of Blockchain Keys and verify each other’s identity. QR codes, RFID, or ultrasound can be used to help the robots identify each other.
Upon confirmation of identity, the first drone will pass on the goods to the second one. This second drone will then carry the goods onto the next interchange or onto its final destination.
Walmart’s AI/DLT logistics chain solution facilitates a quick and smooth distribution method, from the store to the intended destination, without the need for additional human resources.
Walmart holds a fascination with infusing the applications of blockchain technology to its business processes. In July 2018, the multinational retail company also applied for patent for its DLT managed delivery docking stations.
