CAMELLO App is built for the use of OTSAW last-mile delivery robot – Camello for delivering goods/parcels to users. The app enables users to track and collect their parcels from participating providers. Users have to download the app to collect/use the Camello. For example, a defined QR code will be issued to be scanned using the app for the robot compartment to open and users to collect their parcel. Users can also track the estimated delivery time and location of the parcel to be collected through this app.
