Working closely with the BPost back-end and cloud server team, I developed an Android Things application running on Raspberry Pi's. The goal of the app is to help workers with sorting packages at the chutes. The app has a scanner and projector variant, which is running depending on the configuration. By scanning a package on the scanner app, the projector app will show where to put the package together with extra information. The scanning app also warns for various things, like chutes that are becoming full.
