There are plenty of devices that let you keep an eye on your pet at home. Video cameras have certain limitations though. Petbe is a social robot that aims to solve this. It is based on your pet that combines with a smartphone app to provide you with status updates.
Petbe has different motions reflecting your pet’s status. It tilts its head when you touch its screen. The data is gathered using Bluetooth beacons and Raspberry Pi units.[HT]
