The video by Takefumi Hiraki shows phones on a cute set of wheels push packages, ride away when the snooze button goes off, and inch closer to its owner when an important notification comes in.
The accessory comes with a set of wheels, a circuit board equipped with micro-controllers, a USB-serial converter, motors, motor drivers, and rotary encoders. The wheels and casing, themselves, were manufactured via 3D printing.
