Here is a robotic drink delivery system that allows customers at bars and restaurants to order drinks from their phone and receive it faster. Once an order is prepared, it is loaded into Bbot’s basket. The robot delivers each order by traveling along the ceiling track. Your customers won’t have to download an app as they can order via a website on their phone.
Bbot can serve over 100 drinks per hour and up to 15 tables. Your ceiling will need to be at least 9 feet tall though.[where to find it]
