Wake-Up Robot Does It Gently

A robot that detects whether you are awake and gently taps you if not.

For hundreds of years, people have fallen asleep while reading in bed late at night. These days it’s worse, what with us taking phones to the face instead when we start to nod off. At least they don’t have pointy corners like books. While you may not want to share your bedroom with a robot, this wake-up robot by [Norbert Zare] may be just the thing to keep you awake.

Here’s how it works: a Raspberry Pi camera on a servo wanders around at eye level, and the Pi it’s attached to uses OpenCV to determine whether those eyes are open or starting to get heavy. The bot can also speak — it uses eSpeak to introduce itself as a bot designed not to let you sleep. Then when it catches you snoozing, it repeatedly intones ‘wake up’ in a bored British accent.

We were sure that the thing was designed to slap [Norbert] in the face a la [Simone Giertz]’s robot alarm clock, but no, that long-fingered hand just slowly swings down and gently taps [Norbert] on the arm (or whatever is in the path of the slappy hand). Check out the short demo and build video after the break.

Do you want to be awoken even more gently? Try a sunlight lamp. We’ve got dozens in stock, but this one gradually gets about as bright as the sun.
