OBA is a capable and nimble Delivery Robot

OBA is great delivery butler, and very clever too. OBA can deliver food, drinks, medicines, toys and other goodies such as an engagement ring to your fiancee! 

OBA's "head space door" flicks open to allow storage for your goodies. Click it shut to secure it so that no one else but the intended recipient can tamper with it.

OBA will then securely deliver the goodies to where the final customer is, who will then use a personal virtual key to open the top door and retrieve the goodies to enjoy!
